Osprey Nest Platform
The nest is located at the end of North Ocean Ln in Islamorada, Fl 33036 MM 82.5 was placed next to a concrete dock, and have some mangroves around it. This couple is a part of the local Florida Keys Osprey population wish has been declining steadily from the last 20 years, 57% of the population has disappear. These individuals do not reproduce with the migratory Ospreys, for this reason is considered a Monroe County isolated group. 2010-2011 Nest unoccupied 2012 Nest failure 2013 Nest failure 2014 Nest Failure All images taken from approximately 225 feet distance with a scope.

Nesting Diaries

Today after many close ups confirmed the regular Osprey couple nesting the last five years has been on the nest, regular nest clean up, started immediately, typical behavior for this specific female, I seen the male regulary during the rest of the year, he definitely belongs to the Monroe County population classified as a special concern. Detail close up photographs and videos are being collected and submitted.

With the great migration of raptors seeking their winters homes, The Keys are very important to many because it is the last scale to get fuel before crossing the Gulf of Mexico. Many are already reaching their homes, such as Costa Rica, where groups of students and hobbyists are grouped into strategic points to observe the migration, this weekend Key West and Marathon is hosting several events for the raptors observation, many of those migrants are our beloved Ospreys. The nest in Ocean Lane has been busy during the past 4 weeks, a couple of Ospreys have been using it as a perch, but not the regular local couple from the last 5 years;this new female has very distinctive markings, easy recognizable even with a simple pair of binoculars, the local male usually comes back to this area in November, it will be interesting when next month, he comes back to claim his territory.

04/21/2016 by MariIsla
After the dismay from the last family, during the last couple weeks or so a successful family has stop by the platform, is not rare for the fledglings to do short flights with their parents after leaving the nest, the stay with them for months while learning how to fish, at least we can see some successful couple from a near by nest, feathers around the Osprey's face are like finger prints to humans, they are so unique, an easy to compare after 5 years of close up photographs, is great to see at least a successful family. FWC biologist mentioned is not rare for families to use another tall structures around it to train their chicks.

03/22/2016 by MariIsla
After chick A16 died, the female stayed for a week on the nest, a few days later they started to clean the nest, now yesterday and today started mating again, likely an attempt to re- nest because the first one fail.

03/14/2016 by MariIsla
The mother Osprey has been sitting on the nest for two days with her lifeless chicks after they died of starvation due to human harassment, while in other areas there are dedicated groups monitoring, protecting and in general caring about the species, here in Islamorada they just take them for granted and total disrespect. Not sure how long she will stay next to them, but is hard to watch and at the same time, very disappointing.

After many days of traffic to the dock next to the nest with large dogs, allowing their dogs to bark at the birds, kites launched next to it and high winds, as today chick A16 is dead also, the mother just stays looking at it, yesterday after caos finished she did one last try to feed him without interruptions, offering fish but the chick was unresponsive, I wonder when do they know the chick is dead, she still on the nest, fixing thing here and there, they supposedly take their dead bodies out of the nest when cleaning. Is clear now this will happen every year, we are so glad we don't have any attachment to this street, is hard to witness selfish people doing this.

03/11/2016 by MariIsla
This last week, had very high winds, the mother Ospreys seems to stay on the nest covering his offspring most of the time, they were getting big, but I'm sad to report after two days of constant traffic to the nest with pets, Chick B16 is dead, food is limited with bad weather, and is worse when they can't deliver the food because the presence of large pets, this couple seem tolerant to people, but not to pets, this stopped the male from deliver food twice and the younger chick payed the consequences, now is just chickA16 alive, hoping he can survive the constant disturbances.

03/07/2016 by MariIsla
Almost 4 weeks old now, both chicks are doing well,the parents commitment is admirable, looking thru a scope you can see that many times the mother sacrifices her meal times to feed the begging chicks, in literature you can find data showing that females Ospreys loose about 30% weight while raising young, the male don't do that sacrifice, after all he needs to go fishing and spent all that energy , flying, fishing and taking food to the nest. While they are doing their best, I'm not sure how successful the nest will be, this week again authorities intervened to gave them some peace from disturbances. This remind me the fundamental issue with conservation, is not lack of resources, legislation or lack of biological knowledge, is our collective attitude as a society toward nature. In many areas the conservation of specific species depend of committed citizens, the Keys are not a exception, most of the conservation organizations are managed by volunteers, with family and jobs, who dedicate a considerable part of their time to preserve the place where they live, but the ironic part is, that time is spend fighting with other individuals of the same society to don't break the law, if we had a conservationist culture on this country, nature alone can take care of herself, is a none sense waste of energy, if the school system had a area of environmental education as a formal subject, the society can change to benefit the population in general. The Osprey family has 4-5 weeks more to go, if they just get lucky enough to be able to raise a family without extra disturbances.

02/29/2016 by MariIsla
This morning I was afraid to find the two chicks lifeless, after two stressful days for the Osprey family. Weekends attracts more and more tourists to the Keys, all kinds of people and the street where this nest is located was like a parade of families with all kinds of pets walking toward the pier. This caused to the couple great confusion, in their attempts to defend the nest, they launched attacks toward visitors, those reacted by throwing shoes and shouting to the birds, many times it seems like I'm back in anthropology classes where you analyze the most primitive human populations, but we are in the 21st century in a country that is described as developed, unfortunately many aspects continues unchanged or worse. During the afternoon none of the family members manage to eat, the had a Kite constantly approaching for hours forcing everyone to leave the nest, the alert call from the mother made the chicks hide, this happened for hours. In recent conversations with the person who installed the same nest and many more in the Upper Keys, he mention that he always suggests the nest at 45 feet high, because usually in residential areas, 25 feet high are not successful, but many property owners applying for nests permits, want them for their personal entertainment, the families want to watch Ospreys, is not easy in a 45 foot base so they choose the 25 , if they are successful or not, is secondary. This leads me question all the low artificial nest installed throughout the Islands, do we have part of the Osprey population nesting in areas where only will fail? I want it to believe otherwise, but without data is hard to prove, if Nest 4657 is a sample, the panorama is sad. Today the male made the extra effort and kept the family well-fed, all remain in the nest for now.

02/25/2016 by MariIsla
The chicks are 13 days old, and already the sibling aggression is evident, chick A16 considerably bigger than his sibling chick B16, every time the food arrives to the nest the attacks starts, but Ospreys chicks in the Florida Bay are anything but peaceful, sibling aggression has been largely documented by Alan Poole, but just in the Florida Bay. The male is bringing enough food to keep them satisfied. Those little chicks grow so fast and demand so much protein, hopefully the male continues bringing food at the same pace, he seems very efficient this year.

02/22/2016 by MariIsla
The Chicks are now 10 days old, they are growing fast, have lots of food for both of them, they haven't had any constant disturbances on the last weeks, so the female finishes feeding every time, the male has time to go fishing because he doesn't need to be defending the nest, however now he stays very close to the nest on the gate below. After fishing , he delivers the fish, go and dry his wings and sometimes the female call him when she and the chicks are full and and he takes the rest of the fish to eat it somewhere else. I haven't heard the female once begging for fish this last week, hopefully everything continues and maybe we can witness at least one chick fledging.

02/20/2016 by MariIsla
Finally today I saw the chick's heads coming up while the mother was feeding, there are two, they had good weather and enough food, just a couple days ago a stranger Osprey landed on the nest while people was on the dock , so both male and female had to leave the nest completely stress out, the landed on a near by palm tree screeching to the max , luckily the female decided to go back to the nest two minutes later when the people left, in the mean time the male was chasing off the other Osprey intruder, seem he calculated the right moment, taking advantage of the stress situation for them. I'm they still on the nest and the chicks are alive.

02/14/2016 by MariIsla
The family Osprey is doing good, they had a couple good days for fishing, today the winds pick up and the male definitely took half of the day off, just pruning himself , the female called him a couple times to stay on the nest while she went fishing and feed the chicks. Just uploaded some new images, the chicks still too small to be able to capture them on camera, maybe in one week will be possible.

02/11/2016 by MariIsla
02/11/2016 Clutch Hatching Day, the first chick hatched today (Chick A16), a very cold week to be born, but he has a couple of amazing parents, I'm guessing on the next days the rest will hatch, or maybe they just stay with one, that will be ideal, taking in account the lack of food last breading season. I can't see the chicks, the nest is deep, but I see the parents trying to feed and now the female take her food on the nest instead of flying to a near by tree, and the time is right 38 days after the incubation first day. Yesterday they had a lot of drama, a big dead Wood Stork floated under the nest, this attracted Turkey Vultures, the mother was completely stress out, the male was chasing them but they were out numbered, so I had to push the stinky carcasses away from the nest , so the peace came back. UPDATE: finally I was able to verify the hatching, I been observing the female feeding tiny little pieces of fish to her chick, I don't know how many they will have yet.

02/07/2016 by MariIsla
the Osprey couple had a hard week with the weather and winds, but that have not stopped the male and he is bringing enough fish for now. For other Ospreys couples was worse, the 25-35 knots wind the last day destroyed a nest a couple miles away, this nest is so tall , build like a tower next to the HWY, unfortunately half was on the floor today, if they had eggs, this season is over for them, the birds were trying hard to rebuild, maybe they don't need to make it so high next time, I'm happy our nest have a regular height and we don't have to worry about something else, they deal with enough already, two nigths ago a film crew had super bright spot lights pointing toward a property near by, by the nest was directly affected all night, luckily our persistent couple continue with process, they don't have chicks yet, but they have now 35 incubating, they should hatch any day now.

02/04/2016 by MariIsla
The Osprey female is getting very protective of the nest, she spent the afternoon calling the male , as soon as he traded places she went immediately to attack a Pelican sitting at the end of the dock, the Pelican was minding his own business, not even fishing, but I guess the chicks are very close to hatch, the first one I think hatched today but I'm not sure yet, I'm basing my guess on her behavior on the nest, the male on the other hand is very calm, he doesn't get irritated but much, unless the female is screaming with alert sounds, so he comes back to help, funny little family.

02/01/2016 by MariIsla
The couple had a few normal days, very calm, till yesterday, for some reason the male just disappear during the afternoon hours, the female has been begging for food for hours, she can't leave the nest unattended ,making her a defendant, somebody needs to feed her and exchange places, yesterday about 5pm, she was to the point of asking for food to any random Osprey that flew by, last night was very rainy and this morning the male still missing, she took a little rest from the nest to stretch and clean her feathers, keeping a close eye to her nest and now started begging for food again, hoping that male shows up soon, if not she will be obligated to go fishing and leave the nest untended, now that the chicks are so close to hatch.

01/28/2016 by MariIsla
It has become impossible for me to take good picture with this wind and rain, the couple still on the nest, this week has been very calm and quiet for them with the exception of the crappy weather. The female is back to her daily routine, sitting on the nest for hours without moving, and the male is now so efficient that it has taken her too much food, today she decided not to eat her snacks twice, perhaps she got tired of the same menu? This was the rainiest January, hopefully goes back to normal before the chicks are born in the next week or so.

01/26/2016 by MariIsla
I couldn't wait today to check out who was at the nest, yesterday after all the female was missing all day, , very rare , she spent 95% of the time at the nest, but she came back this morning, I wondering, did she need it a break and exercise? no one was feeding the male, after all she was sitting at the nest for two days under bad weather unable to move, we just can assume basing this in our human experience, probably is more complex than that. The male is doing a good job, right now they have plenty of fish surrounding the mangroves, the only problem they had so far is another Osprey trying to land on the nest, when this happens the female screech very loud till the male comes back to chase off the intruder, it works most of the time, is just annoying for them.

01/25/2016 by MariIsla
Today at six in the morning still dark, loud sounds in the water woke me up,at the same time I hear the female the female alert sound , I saw two dolphins feeding by the water's edge, taking advantage of the abundant food. These days the temperatures dropped more than usual, and the couple has been busy carrying soft material to the nest, probably to heat better since they put the material into the nest, surroundings the internal walls. As usual in the high season for tourists in the Keys we had several accidents on the highway, so for two days emergency helicopters have flown too close to the nest, as there is a landing area for emergency close by, this has scared female twice, and today the roles have changed in the nest and the male is who is incubating, this worries me because it was the female who left the nest after having the Bald Eagle threatening them for two consecutive days, this is not very tolerant female, I hope to see her later, they have abut 10 more days to go until the chicks are born.

01/22/2016 by MariIsla
This couple is so determine, the weather had been bad, strong winds, low temperature and rain, and the interesting part is whoever is on the nest when the bad weather arrives, stays there till it finish, they don't move to eat or do anything, if male happen to be there, he waits for the weather to clear, then the female arrives to the nest and then they exchange places, if is the female, she just stand on the nest edge,shake her wings while the weather is clear and then comes back to her incubation position, is clear they know if they know if they move while raining this will create a big temperature drop on the eggs, is always so entertaining to watch them.

01/21/2016 by MariIsla
The couple still on the nest, with their regular routine, I was not able to observe for a week, but everything seems normal, they had a hard week with rain and low temperatures. Today the male had been fishing very close to the nest, didn't spent to much energy moving around, the mangroves help a lot because a lot of fish hid under, s he has his own little fish supply very close. Unfortunately both Ospreys had to leave the nest in the afternoon because a kite was very close, is a windy day and is good for the sport but there is a lot of people out there who don't think about others sharing this place with the creatures who were here first.

01/10/2016 by MariIsla
The last two days had been absolutely beautiful, warm sun, cool light breeze and a flat ocean, the Osprey couple had the regular routine, they both are doing their part, the male is bringing very often lots of food to the nest. But also, with good weather always attracts people, the couple is getting very protective, and they had a very busy morning, between boats approaching the nest trying to catch bait, there is abundant bait around the nest because this is surrounded by mangroves, and noisy people walking at the dock with dogs and kids. I wish they understand those people are not dangerous for them, but on the Osprey word they are just a big threat, the female left the nest for about five minutes, while the visitors clear out, then she resumed her activity, hoping this couple gets use to this soon before the chicks are born, otherwise the nest is just setting them up for a failure every year, all that energy and time is a waste for the Ospreys, and a yearly loss for the species. The male is taking the nest protection pretty seriously, today he was chasing some Pelicans who were taking advantage of the abundant bait and later in the afternoon I was fascinated to see a group of Nanday Parakeets on a Palm tree next to the house, I saw them in Brazil many years ago, they had adapted to Florida's environment after being released from homes where they were pets , but to see them wild so far north is so interesting, of course I couldn't enjoy them for long, because the male Osprey decided to scare them away also, he is doing a great job this nesting season.

01/08/2016 by MariIsla
Super happy to report the Osprey family is doing great, the male may have sharpened his angler skills on the last couple of years, because he brings food to the nest very often and a full fish 90% of the time. In theory from the moment they spot the fish to the catch takes them in average 12 minutes, adding the time to and from the fishing grounds back to the nest, he may be able to bring fish often, considering that 1out of 4 dive is a success. Probably they are mature now , if this continue they have great chances to have a successful year.

01/06/2016 by MariIsla
The couple continue with the incubation process, I just added a couple of images, some are of the nest and the female at the nest separately, and the other couple of the male on a fight with another male I assume trying to take the nest on the beginning of the season. The last two days we had intermittent rain, the female had taken most of the incubation time, yesterday after several calls to her male for food, she decided to get fish for herself and went very close to the nest to harass some pelicans , she had not luck , but by the time she went back to the nest, the male had some fish for her. This morning after she was all night on the rain , he traded places with her for long time, probably is taking them longer to get food, is foggy , raining and a bad visibility on the water. The weather apparently will get better soon, at least the don't have to feed the little ones yet. After 2:00 pm the rain stopped, we had clear skies and happy to report the male had step up his game, now is bringing quality fish, and full fish to the nest very often :).

01/03/2016 by MariIsla
The couple started the incubation period, my theory 4 days ago about the first egg was accurate, counting the days from the first day till now, I think they may have 3 eggs, because the incubation started yesterday, now male and female are switching places on the nest, and didn't seem to be bother much for close human presence, this is very good news, animals have been adapting to all the changes we humans constantly do to their environment, and that is the survival key , now if they still tolerant to mild human activity and have enough fish, this nest may have the chance to succeed. More pictures tomorrow

12/30/2015 by MariIsla
Today was the first day that the female seems very passive, she hasn't move or get disturbed by mild activity around the nest, she stay in the same center area, she may have laid the first egg, but I can't confirm that yet. The male haven't been very good provider the last windy days, maybe just twice a day, in theory he needs to provide her with food, then after her meal, mating, but he just goes directly to the mating these days, the female didn't seem bother by that, the last days she just went and go her own fish. Activity will increase around them, New Years celebration, boats, people, dogs, fireworks, this may help to increase their tolerance or give up the process, time will tell.

12/27/2015 by MariIsla
During the last week, the couple had their focus on matting and bringing new material to the nest, the female is spending more time each day on the nest. Is very windy and the Keys are at full capacity, with the Holidays the amount of people on street increased a bit, going from a silence November to a very active December for the Ospreys, the these days their tolerance is being tested with a few people passing by their nest and Kite boarders launching their kites very close, the last day the male had to drop his prey twice when flying to the female because the kite was to close. The success of the couple will depend of their capacity to adapt to the more extreme changes coming, this nest is a small representation of what had happened to the Osprey population on the chain of Islands, the developing and lack of awareness is pushing this species to the edge, I don't think they will be successful this season, but still hopeful, the sad part is the average Keys visitor don't even notice them.

12/18/2015 by MariIsla
The couple is very active, last week has been on the nest 70% of the day either fixing the nest, or mating,comparing pictures from the last 4 years and now I can see the feathers on their faces had changed a bit, this tells me they were immature the last time they nested, hoping they have a successful season this time.

12/10/2015 by MariIsla
The couple has been matting every day since the last two weeks, the male arrived in the middle of November, now both birds are fixing the nest and keeping their territory while the male occasionally provides food for the female, they seem very active and probably we will have nesting this year.

The nest didn't produced young on 2014 or eggs. I'm not sure what happened during December, usually this is the month when they get ready for nesting or star nesting, I was out of the country for 3 weeks during December, so I don't have any observations or can guess what the nest failure reason was.

03/25/2015 by MariIsla
The couple didn't produced eggs this season, I just have two theories, one the didn't tolerate all the human activity around the nest, this year was not a sign or warnings to visitors about the nest or they didn't have sufficient resources (food) to sustain a nest.

03/14/2015 by MariIsla
After a few weeks with not activity on the nest, today on the morning hours the same couple was clening the nest and the males was delivering food to the female, however the nest don't have anything, video taken with a drone from last week show the nest without any trace of eggs, just some old fish bones. Maybe they haven't give up yet.

02/28/2015 by MariIsla
Well after a week observing the nest every day, seems like the couple decided to abandon any nesting attempt, they never came back to the nest or resume any activity, the nest had been empty. Seems like the human disruption it was to much for them, the nest is relatively low, and easy to access, at least they didn't have chicks yet, . The human population in the keys is growing so fast, all the available nesting are gone due to residential or commercial constructions, so the 90 percent of the Osprey populations depend of artificial platforms, but not all of them have the ideal conditions, or the circumstances are changing around them are changing., not to mention the lack of knowledge about this species on the general human population, many just do the wrong thing for ignorance and others just for lack of care. I will post any news if I see any new activity or a different couple.

02/21/2015 by MariIsla
The last two days we had very cold weather and sporadic rain showers, the female Osprey came yesterday for a short time at the nest, but she didn't stay long, is almost the end of February and they don't have eggs, al the other nest around are in the incubation process, the only difference this year is we didn't stop anybody for walking up to the nest or installed any sign warning them about the activity, not sure is the increased human activity the last month is the reason or they just don't have enough food sources to star the reproduction, the did mate several times since December.

02/17/2015 by MariIsla
This couple don't have eggs yet, last year they laid the eggs about February 02, during last week they been defending the nest pretty hard, no use to the increase human activity around, the insisted in chasing and warning people close by, instead of fishing, but for today seems like they have giving up, they did not visit the nest during the entire day, or even fly around it, maybe they finally understood this area is not ideal for nesting or maybe they are waiting around to the human activity to slow down.

02/03/2015 by MariIsla
The couple still mating and defending the nest, today it was the first day the female didn't abandon the nest during the day, just for eating what the male offered, that was not much, I'm thinking they may have eggs or started the incubation process today, but probably tomorrow I can confirm that,the season seems going normal , there are another 4 active nest around this area.

01/20/2015 by MariIsla
Is been long time since I updated the nest, the Osprey maintain their territory and presence on the nest, the same ritual everyday, the male providing food for the female, everyday they spend more and more time on the nest mating every so often, however I haven't seen incubation behavior, I don't think they have eggs yet, the last 3 days they had been disturbed by strangers too close to the nest, in this case because they don't have eggs maybe is good so they won't produce eggs this time, I wish them the best but on this neighbor hood the disruption will be constant, I don't wish to witness another small bird left alone and die for starvation like last season.

01/01/2015 by MariIsla
First report of the year, the couple seems to have their normal courtship routine, last night our next door neighbor had some very loud and constant firecrackers, I was worried the ospreys wont tolerate them because they were too close, but this morning both of them were on the nest and a regular third intruder Osprey too, no signs of incubation behavior yet.

12/27/2014 by MariIsla
For more than two weeks I was unable to observe the nest, the pair continue on the nest, I'm not sure if they have eggs already, they seem to be changing positions and never leaving the nest alone, maybe one more day of observation will tell me what is going on with the nest.

12/07/2014 by MariIsla
The Ospreys have been pretty base this last week, bringing new material to the nest and mating, now they spent more hours at day on the nest, however I still thinking they are so inexperience, sometimes the male drop the new stick before he gets them to the nest, but I guess time will tell.

11/30/2014 by MariIsla
The last 4 days the Osprey are spending almost all the day light hours on the nest, mating and rearranging materials, the male has been working hard offering fish to the female, so everything seem progressing smoothly.

11/26/2014 by MariIsla
Every day the couple spend a few hours on the nest, today both of them dedicated the morning for cleaning and rearranging material, mostly the female. This year they are bringing food on the nest and eating the food on the nest , different behavior that the past 3 years.

11/12/2014 by MariIsla
The cuple had been defending the nest during the afternoon, maybe during two or tre hours every day, the male had been offering to he female, but she doesn't seem interested, neither of them had done anything with the nest, I have observed 3 other couples around, whom have the nest looking good , hopefully this couple hurry up and get more efficient.

11/10/2014 by MariIsla
Today was the first day I saw the couple mating, the female has been perching on the nest for hours observing hundreds of Turkey Vultures migrating south over her nest.

Finally, two weeks ago the male came to the nest, but has only napped, but without giving any kind of maintenance to the nest,I guess he is been waiting for his female. This nest was cleaned by landscapers at the end of last season because had many strings that represent a danger to adults, as for chicks. Today was the first day that I saw the couple together, the female arrived during the afternoon, she immediately started to rearrange nest stick and making vocalizations, I can imagine what was she telling the male after founding the nest so messy. I'm glad to see she is alive and well, I was never sure of what happened after she left the Chick # 1, I had many doubts and questions, now my theory is that the mother abandoned him after so much harassment by the bald eagle and left the final task to the male, crossing my fingers to finally have a successful season with this pair.

I just received the news about chick B, who will be in a Raptor rehabilitation facility the rest of his life due to the injuries on his wing, he/she wont be able to fly. Wishing a better outcome to the Ospreys next year.

05/07/2014 by MariIsla
Since chick A died, the father has been close to the nest, many times just observing his chick for long periods of time, clearly he is aware the chick is not longer alive because he hasn't tried to deliver more fish, today during the morning hours he spend lots of time cleaning his nest and rearranging materials, is difficult because this nest has a lot of synthetic materials, as many people observing Ospreys know, in theory is a duty of the people who build platforms for Ospreys to eliminate hazardous materials from the nest as need it to avoid adult Ospreys and nestlings entanglement, I'm not sure if this nest ever had maintenance, my guess is never for the amount of ropes on it. Another adult Ospreys had been trying to take the nest, so the father has been very busy defending his territory. This will be my last post till I have news about chick B and his rehabilitation.

05/04/2014 by MariIsla
After a week since chick A pushed his brother out of the nest, the mother left the day after, the father took over bringing fish to the nest and defending the nest, but I think the nestling was having difficulty tearing pieces from the fish to eat, the father never feed him directly other than the delivery, yesterday and last night we had small storm and today the chick is dead, I saw him in the same position for hours not movement and the father was around in the morning hours, my best guess unfortunately he died from starvation, sad ending for this family, chick B still in the rehabilitation center getting better. I never saw the mother around again, she either left the nest after 3 days of harassment from the Bald Eagle or she was injured, I guess I will know the answer if I see her in the next breading season.

05/01/2014 by MariIsla
Since the mother left the nest 5 days ago, the father have been working hard feeding the remaining chick (chick A) , he is eating on his own, sometimes he have a hard time because the fish is not too soft, when this happens he just leaves the fish aside on the nest, this attracted another adult Osprey and now she is trying to steal the fish from the nest when the father is not around, this family just had so much drama the last week, chick A is 54 days old now and hopefully he will fledge soon, but accordingly with Alan Poole in non migrating populations may take longer.

04/28/2014 by MariIsla
Since Saturday I never saw the mother Osprey again, the chick sleeps alone and now is learning to eat by himself, seems like all the job is up to the father , today he delivered partially eaten preys to the nest and was watching the nest from a near by palm tree.

04/27/2014 by MariIsla
The outlook for the nest is not very positive for now, since Friday when one of the chicks was pushed from the nest by his older sibling, the female does not remain alongside the remaining chick on the nest, yesterday afternoon she was on a palm tree near the nest, but for the rest of time yesterday and today she was completely absent when I was observing abut 4 hours, I have not seen any of the parents deliver food to the nest either, as the chick is constantly asking for food. It is possible that she is leaving food in the nest for the chick to feed himself, but I failed to see this behavior, the chick is 50 days old today.

04/25/2014 by MariIsla
This morning the first meal the male had cough was stolen by the same Bald Eagle, this time by fortune the the female didn't have to leave the chicks alone to defend their nest becasue the male took care of it, but unfortunately their lost their meal and the female is insecure leaving the nest for the eminent danger. In studies done in the Everglades [ EFFECTS OF BALD EAGLE TERRITORIALITY ON NESTING OSPREYS JOHN C.OGDEN] osprey nestlings remains were found in active Bald Eagle nest, I so wish better luck for this family , is so close to finish the process, they didn't need it a Bald Eagle coming to the scene, now is when the chicks need more food. Unfortunately after the first meal of the day, the sibling aggression was intense at the point that chicks A pushed chick B out of the nest, I went to the nest base hoping maybe the chick was on the mangroves near the nest , but he was on the ground, we took the chick to the only rehabilitation facility close to the area, and the future of chick B is uncertain. Definitely now the job for the parents will be a little easier, hoping chick A fledge successfully in the next two weeks.

04/23/2014 by MariIsla
The weather improved a lot, 5-10 n. very sunny skies and lots of migrating "Mullet" close to the nest, the male had not increased yet the delivery rate, most of the preys are partially consumed and quite not enough to satisfy the growing chicks, but both still alive and active. However right when the babies reached the 6 weeks of age and there is not more human disruption, a Bald Eagle came to the scene,I though I saw her during the morning hours with a naked eye, but I was not sure or my brain didn't want to accept the reality because this represent more problems for the nest, today the Bald Eagle stole a prey from the mother in the afternoon hours and is harassing the nest. There is a Bald Eagle couple living about 10 miles south from the nest, is not very common to see them around this area, and hopefully they stop coming for now.

04/18/2014 by MariIsla
Windy days, but the chicks had at least 4 meals at day, the preys are small, chick A is almost his mom size and is exercising his wings more often, while chick B just imitates everything his mom do, another Osprey was trying to approach the nest again today , this kept the male busy for awhile, the female feels more confident leaving the chicks alone for some exercise and bathroom break after meals, chick A is 41 days old today, chick B probably 38, I so wish they can be banded, curious about their sex and future.

04/14/2014 by MariIsla
The weather improved considerably today and the ability of the male to fish too, the family had a lot of activity, the female was dedicated to rearrange the nest with new materials between meals, the chicks were so full that spent the time sleeping, but chick B is more active now, mimics mom's vocalizations, spend time watching the surroundings from the nest edge and even works trying to move materials in the nest, during meals he learned to hide behind mom and catch the occasional bite to prevent attacks from his older sibling, he have a size disadvantage but have a good strategy and is working great now.

04/13/2014 by MariIsla
Finally this morning the male came to the nest with a small prey around 9:30 in the morning, the chicks were begging for food and the female was hungry. I don't see a increase on meal's frequency , these chicks definitely need more protein. Some studies in Monroe County determined that chicks mortality in areas with food stress happen a few weeks before the chicks fly, definitely a nest is qualified as a successful after 6 weeks if the chicks still alive, these chicks are 31 and 33 days of age, the next two weeks are critical to determine who will survive, the mother is a realty good parent, she goes fishing when the male failed to provide regular meals, but not sure how effective this will be with two large chicks.

04/12/2014 by MariIsla
During the last two weeks the weather has been too windy, yesterday and today especially, not ideal for this family. The two chicks are growing so fast, now chick B is challenging the authority of his older brother, which gets him into trouble, they did not have much food today, the last time I saw the male was about eleven in the morning, and disappeared the rest of the day, during the afternoon the female had to go fishing twice, both times returned fast with needle fish. I hope the male is alive and did not return to the nest because he was empty-handed, he did this before but not for so long, is not a ideal situation for a single female Osprey raising two chicks, hopefully I will see him tomorrow morning.

04/10/2014 by MariIsla
Today on my morning walk did a quick check on the nest, saw the two chicks full and the mother pruning herself. The weather is not perfect, we had a cold front and the male is being a good provider under the circumstances, strong cold winds and rain. However this was not enough during the afternoon hours for the chicks, they are bigger and demand more protein, so the attacks from chick A to chick B were quite brutal, so chick B strategy to survive this attacks was to avoid eye contact with chick A to minimize confrontation and adopt a submissive posture, again not a easy viewing, but I have hopes that chick B will weather the storm and make it through, will see in the next 2 weeks.

04/10/2014 by MariIsla
I can not be happier, despite the fact that the last days were very windy, the male took enough food to the nest to keep the whole family well nourished, not to mention that the nest has not been disturbed by humans in the last week. Today the chicks are a month old (-/+ 2 days), the first feathers begin to cover them especially chick A, who still is a bully, but at least his little brother is getting enough food.

04/07/2014 by MariIsla
Yesterday and today was very positive for the family, the male despite a rather windy weather, brought abundant fish to the nest, to the point where the two chicks and the mother were full and have to discard the remaining food, chick B is getting stronger in just two days of good nutrition, he is the only one imitating the mother's vocalizations.

04/07/2014 by MariIsla
Last night we had fireworks near the nest, I was worried about the effect this would have on the chicks, but happily this morning everyone was in the nest. The parents have gone through four fireworks since January , three of them had place within 0.5 miles and one of them exactly one mile away from the nest. These ospreys that make their nests in urban areas, seem more tolerant of these activities, near Oceana nest there are two more nests that have been active for years, both in front of resorts that have fireworks at least once a month. Today it was great fishing day for the male, and when I was thinking chick B possibilities were none, all the sudden the female placed the fish between both of them and feed chick B exclusively, he was in need of some protein.

04/06/2014 by MariIsla
I observed the nest just a few hours today, saw the female hunting once, got a needle fish, feed chic A and herself, it was not enough for chick B, he was behind his mother, where his older brother had push him. The weather is not ideal for fishing again, but at least they don't have more human disturbance, so the female feel more confident leaving the nest for fishing, the male is not as efficient, he needs to bring bigger preys. A different Osprey landed on the nest this morning , both parents were on the nest, this caused a violent fight between the father and the intruder, I'm assuming is a young or migratory Osprey looking for territory. Chick A have so much size advantage that I'm afraid every time I take my scope I wont find chick B alive, chick A will be 4 weeks old in tree days. The mother don't intervene with the bully behavior, I suppose for the species and the mother is better to raise one strong chick than two weak ones, this is called brood reduction, many studies showed in Florida this is influenced by inadequate food provisioning by males, it depends of the male's ability, experience or motivation to provide food to the nest, but is more common in nest with 3 nestlings.

04/05/2014 by MariIsla
Chick A=older Chick B=youngest The weather has improved the last two days, today in the morning I saw all the family, all apparently had already eaten. The mother went fishing and took the mullet nest, but this time she didn't feed the chicks, she left the prey in front of them, probably to encourage them to feed themselves and start biting fish. Luckily law enforcement FWC has come forward to educate people whom with their actions caused negative impacts to the nest, this is a greater opportunity for the couple to raise the chicks successfully. Chick A is very active in the nest wiping feathers and exercising his wings, chick B on the contrary does not show much activity, but still alive. Now as a consequence of human interactions, every time the parents deliver fish to the nest, some seagulls surround the nest, hoping to get some too, but If the male is around he can chase them away fast. It will be interesting to see what will happen when the parents star to deliver fish to nest for the chicks to eat alone. Today was good to see they had plenty of food, one hour later the male delivered more fish , but all the family was satisfied, so he took his fish with him and went to eat it to a nearby palm tree.

04/03/2014 by MariIsla
Chick A=older Chick B=youngest During the morning hours, the male delivered partially consumed mullet, this preys are so small, it was enough to feed the mother and chick A, this chick sent chick B to the corner with the head down till he is completely satisfied, then the mother started feeding the chick B. During the afternoon the female was begging for food and the male was completely absent, the mother decided to take a risk, left the chicks alone and went fishing, (probably she was starving too) came back with a nice trout, good enough to feed everybody and then some, this time chick B stood up to his bully brother but lost the battle because the size difference, is more evident everyday chick A gets more protein, at least 80% more. One hour later she made another trip, but had to come back fast because a family was visiting the dock. If she goes fishing more often probably will be able to raise two strong chicks, but is risky, I seen Hawks and Owls around the neighborhood, the chicks are small and easy prey. Hoping for a good weekend for this family.

04/02/2014 by MariIsla
Today again a very windy day, the family did not have much to eat, is difficult to see when the younger brother didn't get anything and still hungry when the partially consumed fish is gone, the biggest brother dominated the meals, the fights were so strong that his younger brother have several injuries around the neck, his older brother is a big bully, I have less hope for the young one because he learned to keep his head down during the feeding, all this can change if the circumstances for the couple change, less nest disturbance + better weather= more fish to the nest. The female continued for about an hour with the "begging calls", the male was hunting right next to the nest, trying hard with not results. The forecast for tomorrow is the same, I guess a bad fishing week for everybody.

04/01/2014 by MariIsla
This day despite being cold and windy, the male took enough fish to the nest, the chicks ate till they were fully satisfy. During the last 3 weeks the female had dedicated 99% of the time to care for the nestlings, I only observed the male feeding on one occasion. Today when the family was obviously full , the female was cleaning and reorganizing the nest while the male was chasing birds around who were very close to the nest, including a Great Blue Heron and a Little Blue Heron, the interactions were very aggressive and the birds got the point. Now the nestlings started to defecate over the edge of the nest, to keep it clean, interesting to see the instincts a such a early age. During the morning hours one person opted as always to feed cat food to the seagulls within at 10 foot proximity , which kept the female and male stressed because this attracts about 50 seagulls flying over their nest, but luckily everybody had eaten at this point. During the last hour of the day, the female went fishing, took back a big snapper to the nest, but she didn't eat or feed the nestlings, just sat on the fish till dark, is the first time I saw this kind of behavior, (storing fish), maybe someone who has more observation time can give me a clue.

03/31/2014 by MariIsla
Windy and cloudy day, the morning was busy for the Ospreys, chasing another osprey approaching the nest and trying to scare away people on the dock, in total during the day they had 2 feedings, a nice size lady fish and a partially consumed snapper, the older nestling is growing fast and getting stronger, having the size advantage over his youngest sibling is getting more food.

03/30/2014 by MariIsla
The first period of the morning feeding was interrupted by two people cutting bait on the dock, throwing food to the seagulls, and fishing nets in the water, this attracts many birds around the nest obligating the female to leave the nest with the prey so they don't steal it. We can only hope they get use to this activity or choose another location next year, this nest was a failure the last 3 years, they are constantly harassed by people with other priorities. Fortunately the nestlings are big enough to endure exposure to the sun without the mother protection for short periods of time.

03/29/2014 by MariIsla
The last two days the weather was influenced by a cold front, fortunately this allowed the Ospreys feed the nestlings with less interruptions by humans, allowing the smaller nestling to eat better, besides the occasional confrontation with another adult Osprey trying to steal the fish from the nest, the male always scare him away successfully. The food fights between nestlings begin at this point, the next two weeks will be vital for the youngest nestling, because clearly the oldest is dominating the feeding time, and the young just eats when his older brother is satisfied and if is any fish left, the water will be better tomorrow, hopefully the male can bring more food and people cooperate with this couple, is just a few more weeks and they will be done with the process.

03/26/2014 by MariIsla
When both parents need to spent time and energy defending their nest from intruders (in this case humans and another Osprey), instead of fishing, the survival chances for the nestlings are reduce to 50%, one of the nestlings is getting very weak already. Today during all the afternoon hours a person was working on a boat right under the nest, for this reason the male stay with the female guarding the nest instead of fishing so nestlings didn't get feed.

03/25/2014 by MariIsla
We had a rainy night and morning, the female was sited tightly on the nest, to keep the young warm, because they are too young to be able to thermoregulate. By noon the male had some aggressive interactions with another Osprey trying to approach the nest, and has been slow for fishing, the second time the male came back to the nest empty handed, the female waited for some clouds and warm weather and left the nest alone for about 10 minutes, it is rare at this stage, but she came back with food.

03/24/2014 by MariIsla
The nestlings are growing fast, the last two days were very calm, good for fishing, the male took to the nest in average of 5 fish, mullet mainly, however they had more than usual human activity under the nest with a new family constant visiting the dock, so they spent a lot of energy defending their nest. But over all their your were feed equally. The white down was replaced by charcoal-colored down and they started to grow feathers today.

03/21/2014 by MariIsla
Today during the morning the Osprey female didn't have the opportunity to eat or feed the nestlings, constant humans approaching their nest, when the female made the distress call, the male comes back to the nest to care for their young and stop fishing, the more frequent the distress call are made , the less chance the male has to fish and this decrease the opportunities to feed the nestlings, the survival chances are less for both, on this nest probably just one nestling will survive if this continue so often.

03/20/2014 by MariIsla
The two nestlings are easy visible with the naked eye, the first one seems to be dominating and taking most of the food, now it depends of how much fish the male provides, if is not sufficient , just one will survive.

03/18/2014 by MariIsla
As the nestlings grow, the couple become more and more defensive of its territory, today the were chasing Blue Herons and Pelicans who dare to fly to close to their nest. Finally had a image with the mother feeding, from my point of view I can see two nestlings.

03/17/2014 by MariIsla
Nestlings: For the first time I had the opportunity to have a clear view of two nestlings, my point of observation is a home balcony, very close to be the same nest height, so is difficult to have a clear visual of the nestlings. The ospreys continue with their daily routine, today with very little human activity around it.

03/16/2014 by MariIsla
Today is not a good fishing day, very windy and the water is murky, the male failed to provide much fish to the nest, but he never came back empty handed, , today was bringing more materials to the nest, while the female arranged them. In the afternoon hours she been just providing protection to the nestlings and producing vocalization to call the male, the last fish of the day was good enough to compensate.

03/15/2014 by MariIsla
This morning the couple was very busy, another Osprey was flying around the nest, so they were mainly defending their nest for about an hour, after this the female started to bring fresh material and reorganizing the nest, cleaning and feeding the nestlings at the same time. They partially covered the nestlings with palm tree fiber. 4:04 pm a neighbor purposely walk with a dog toward the nest, the female was flying around the nest with warming vocalizations for 10 minutes, without the chance to land on her nest, this finish till the person moved away. The person is aware about the Ospreys sensitivity when nesting, but they keep on going, this was the same scenario last year, now this is happening everyday, hopefully this Osprey become tolerant and continue with the process, however is a big energy waste for the bird who is depending on the male for food.

03/14/2014 by MariIsla
Today was a very good fishing day for the male, the prey size was good enough to feed everybody, I still can't see the how many nestlings they have, hopefully nest week will be more evident. While the female was fishing the male was reorganizing and cleaning the nest, it was a windy and cool day for them, but they both had success fishing.

03/13/2014 by MariIsla
Today was very little activity in the afternoon a person visited the nest, forcing the female to leave the nest and nestlings for 10 minutes, after 6 pm the male did not return with food, but female remained on the nest.

03/12/2014 by MariIsla
The pictures are taken with a high power scope from a balcony. Yesterday the male supplied fish at least 6 times during the day the female consumed half of fish , feed the nestlings and then she give him back close to half of the fish to the male, then he takes to the fish to a nearby palm tree to finish eating and since then another Osprey has been surrounding the nest.

03/12/2014 by MariIsla
In the Florida Keys we have migratory and local populations, this couple is to be local , I been observing this nest fro 3 years. The nest is close by many resorts and its location made it difficult for the couple the last 2 years to stay. Street residents use the dock next to the nest and this seems to bother the birds an lot, they have a lot of tolerance to noise but not tolerance to people or animals close to their nest. This year we been trying to avoid as much as possible human presence close to the nest and it was successful till now, because finally the have nestlings. In March 08 they were exposed to a very loud fireworks about 300 yards of distance from the nest, it was very dark, and it was not possible for me to see how much disturbance this created to the female, but the next morning was the first time we saw her feeding.
