What to look for
a
Adult Arrival
Look for 2 adults on the nest. The adult pair will show pair bonding behaviors such as vocalizations, aerial sky dances, and the male feeding the female fish. You may see the pair copulating, which typically begins 14 days before laying eggs.b
Incubation Initiation
Females will lay 1 - 4 eggs at a rate of one egg every 1 - 2 days. After laying, incubation starts. Look for adults taking turns sitting low in the nest incubating eggs. The incubation period can last 35 - 43 days.c
Clutch Hatching
Chicks hatch ~39 days after incubation begins. Look for adults bringing food to the nest and making "head bows" into the center. Chicks typically can't be seen until they are 2 - 3 weeks old, so feeding behavior is the only way to know chicks are there.d
Nestling Count
Around 4 weeks after hatching, look for the heads of chicks to show over the rim of the nest, particularly when adults bring food to the nest. Other times they lie flat and are harder to see. Count the number of chicks in the nest before they learn to flye
Fledgling Count
Chicks begin flying around 7 - 8 weeks old, and are still fed by the adults. Count the number of chicks who have successfully fledged the nest and are observed flying.f
Chick Last Observed
4 - 10 weeks after fledging, chicks begin leaving the nest area to migrate south, once they have learned to fly and feed themselves. Record the date that the last chick left the nest.x
Nest Failure
Look for signs of nest failure like adult abandonment, adults no longer incubating eggs or feeding young.Review All Observations

Mary K reports:
An adult osprey was observed coming out of the nest, sitting above the nest, then flying away.
NOTE: We are confident that fledging has taken place.
07/24/2023 by CarolC
Carol T and Mary K:
Based on the timing, and other info entered into the reports, it surely seems like there were two chicks, and they would have fledged by now.
NOTE: The osprey reported above the nest on 7/23 seems to be confirmation that the nest is empty and that osprey is either an adult or more likely, one of the fledged chicks. We estimate that they both fledged sometime between July 12-21. We will split the difference and estimate the date as July 17.
07/23/2023 by CarolC
Mary K reports:
One osprey was observed sitting on the bar just above the nest, not in the nest. It looked like an adult but it’s hard to be sure from the far distance.
07/12/2023 by CarolC
Carol T reports:
I observed an adult Osprey standing in the nest along with one smaller Osprey
06/20/2023 by CarolC
Mary K reports:
The top of two similar sized heads were observed sitting in the nest.
NOTE: Based on this, we will increase the nestlings to 2.
06/03/2023 by CarolC
Carol T reports:
An adult in the nest appeared to be feeding or tending to a chick (or more) in the nest, which were not visible yet.
05/31/2023 by CarolC
Carol T reports:
I saw the same scenario at Mary’s nest. Sure looked like an adult was bending over repeatedly feeding a chick. No chicks were visible.
05/19/2023 by CarolC
Carol T reports:
5/19/23
There was an adult Osprey visible standing up in the nest. It was bending over repeatedly, but I couldn’t determine if it was feeding itself or a chick.
NOTE: This possible feeding behavior supports the hatching we estimated
about May 1. We are listed 1 chick until we can confirm the number.
05/07/2023 by CarolC
Carol T reports:
There was one adult Osprey sitting by the nest, and I think there was a chick visible in the nest. As Mary and I have observed, it’s really hard to make determinations at that nest because of the long distance away.
NOTE: probably hatching occurred around May 1, but we are not sure.
04/30/2023 by CarolC
Mary K reports:
An adult osprey was observed flying into the nest and about 10 minutes later flying out of the nest, plus what appeared to be the top of a baby chick’s head in the nest.
NOTE: This probably is the top of the adult's head if our incubation date of 4/14 is in the ballpark.
04/16/2023 by CarolC
Mary K reports:
4/14/23 and 4/16/23
On both dates, I was only able to observe what appeared to be the white top of a head in the nest.
NOTE: Based on this observation, it is probably that incubation has begun. Marking it tentatively as beginning 4/14/23
03/29/2023 by CarolC
Carol T reports: Two Osprey visible in the nest. One looked larger than the other, so maybe adult and juvenile. Too far away to be certain.
03/21/2023 by CarolC
Carol T reports: 3/21/23
There was movement in the nest which looked like one adult
02/18/2023 by CarolC
Mary K reports: There does not appear to be any change from my last observation. No ospreys were sighted.
07/24/2022 by CarolC
Mary K reports: No activity at the nest for the past two days. I believe they have all fledged.
07/04/2022 by CarolC
NOTE: We have been unsure on the number of chicks in this nest and previously listed just one. This latest observation makes us think there are three. We will adjust if this doens't appear to be correct.
07/04/2022 by CarolC
Mary K reports:three osprey chicks, all the same size, were observed sitting in the nest, one occasionally flapping it’s wings. I could only observe the upper part of their bodies.
NOTE: I “assumed” the three osprey in Nest 7293 were all chicks because they seemed to be the same size, but I could not see the entire bodies.
06/19/2022 by CarolC
Mary K reports: slight movement was observed in the nest but it was difficult to determine if it was an adult or a chick.
06/12/2022 by CarolC
Carol T reports as sub for Mary K: One Osprey busy with something down in the nest. No sign of any chicks yet.
No other activity around the nest
06/04/2022 by CarolC
Carol T reports as sub for Mary K:
Mary’s nest had the exact same activity at her nest. One Osprey bent over, tending to nest or chick(s) in nest.
NOTE: Based on the last couple observations, we assume hatching has occurred. We are listing 1 nestling until we can confirm the number. May 22 is just a guess on when hatching took place based on the observations.
05/29/2022 by CarolC
Mary K reports: an adult osprey was observed sitting in the nest, occasionally flapping it’s wings.
05/22/2022 by CarolC
Mary K reports: An osprey was observed sitting straight up in the nest.
NOTE: IT is possible that incubation has ended and this was an adult sitting up.
05/15/2022 by CarolC
Mary K reports: the top of an osprey’s head was observed popping up and down in the nest. Then, another osprey flew into the nest.
05/01/2022 by CarolC
Mary K reports: Initially there was no activity at the nest. Returned about 30 minutes later and observed an osprey perched on the top edge of the nest, intermittently flapping its wings.
04/24/2022 by CarolC
Carol T reports: No activity to report for the half hour I was there. It was early afternoon, so probably not a good time for catching activity.
04/10/2022 by CarolC
Carol T reports: No activity. I have a feeling there’s incubation in process, but as we know, the nest is so deep it’s hard to discern. We need to be lucky enough to see a male coming and going to confirm.
NOTE: Based on separate observations today by Carol T and Mary K, it is possible incubation is underway. We have tentatively listed it as beginning 4/10 but can adjust as needed. Activity picked up between 4/3 and 4/10.
04/10/2022 by CarolC
Mary K reports: a lot of activity was observed, two ospreys were busy flying in and out of the nest. At one point, one osprey was sitting on the nest, and frequently flapping it’s wings.
03/15/2022 by CarolC
Carol T reports: It appears that both Osprey have returned to the nest, one sitting up in the nest and another flying in and quickly flying back out. Maybe delivering nest material.
03/11/2022 by CarolC
Carol T reports: No Osprey at or in the vicinity of the nest Nest is too far away to tell if any nest refurbishing has occurred
03/04/2022 by CarolC
Carol T reports: Observed the nests( and 7016) for about 30 min. and there was no bird activity of any kind.
02/20/2022 by CarolC
01/30/2022 by CarolC
08/08/2021 by CarolC
Mary K reports: These two nestlings have fledged. We cannot be sure of the date, but it probably was in late July. July 27th is simply a guess.
07/11/2021 by CarolC
Mary K reports: an adult osprey was observed and appeared to be feeding chick(s) inside the nest.
07/05/2021 by CarolC
Mary K reports: what appeared to be the heads of two chicks were observed in the nest.
06/21/2021 by CarolC
Carol T reports: When I arrived there was an adult Osprey standing at the side of the nest and a good sized chick sitting at the front edge of the nest. (With my binoculars I was able, just barely, to verify that it was a chick…not an adult. The wings had the speckled markings of a juvenile). I also thought at one point I might have caught a glimpse of another head, but I can’t be sure.
The chick stayed visible the whole time I was there and was even practicing “wing flapping”!
(Because the nest is such a great distance away, the photo below is not very clear and doesn’t show the detail I saw through my bins. However, if you pinch the photo out some, you can see the speckled feather detail a little bit)
06/18/2021 by CarolC
Mary K reports:
An adult osprey was observed sitting in the nest and flapping its wings.
06/11/2021 by CarolC
Carol T reports: One adult was sitting up in the nest. No sign of chicks large enough to see yet.
05/19/2021 by CarolC
Carol T reports for Mary K: there was no activity at Mary’s nest while I was there
05/13/2021 by CarolC
Carol T reports for Mary: This nest is full of activity!
An Osprey flew out of the nest as I arrived. The mate was in the nest and appeared to be feeding a young one. I saw one small head emerging.
Several minutes later the male(?) Osprey returned, sat on the structure for a few minutes and then flew off again.
All good news that points to at least one chick in the nest!
05/06/2021 by CarolC
Carol T reports: Mary Kelly’s nest had two birds visible in the nest.
One was an adult that looked like it was eating.
The other one was smaller, so I’m guessing it was a chick. It was standing up looking out of the nest. NOTE: Based on this and the previous observation, we will assume there is at least 1 chick in the nest.
This nest is so far away that I’m not able to see much in the way of detail and markings, even with my good binoculars.
Hoping for better lighting on the next visit!
05/02/2021 by CarolC
Carol T reports: No activity spotted at this nest until 5/2.
An Osprey was sitting on the structure at the edge of the nest and a second Osprey was in the nest and appeared to be eating. I could see wings flapping and head bent over in an eating posture. (I’m guessing the male brought in a fish for the female who’s been incubating.)
04/25/2021 by CarolC
Mary K reports: One osprey was seen flying into the nest, a little while later, two ospreys flew out of the nest.
04/19/2021 by CarolC
Mary K reports: I did not see any activity, though it’s possible the female osprey may be sitting on the eggs, and cannot be seen.
03/21/2021 by CarolC
Mary K. reports: I went to the nest today and observed activity in the nest: slight movement of the top of the osprey’s head. Upon further observation from a slightly different location, I saw the osprey fly out of the nest. He flew up from the nest and then quickly flew back down into the nest.
NOTE: Based on this report and the previous one, we are assuming that there is an egg and that incubation has begun.
03/20/2021 by CarolC
Carol T. reported that while monitoring her nest, she saw an Osprey in nest, #7293, on 3/17 and 3/20.
Both times it was in the nest for awhile.
03/07/2021 by CarolC
Mary K reports: I did not see any activity at the nest today. I saw 2 ospreys flying in the vicinity but they did not fly near the nest.
02/24/2021 by CarolC
Mary K and Carol T report:
When Carol T was checking her Nest yesterday, she saw an Osprey in Mary K's nest that seemed to hang out for quite a while
02/23/2021 by CarolC
Mary K reports: I viewed the nest today, which looked pretty much the same as my last visit.
I did not see any osprey activity at the nest; however I did see as many as five birds which looked like osprey flying nearby.
07/29/2019 by CarolC
Linda O reports: I visited Nest #7923 today and did not see these Osprey in or near the nest. What I did see was crows all over the nest and coming and going routinely. So I would say that the young have fledged.
I thought the crows in the nest an interesting situation.
I then looked over to the nest closer to the PSD Building, I think Carol T was monitoring that one, and saw crows in that one also. I had heard osprey calling and then an Osprey came in over to the nest and chased the crows away. I then saw the 2nd Osprey flying around. The one in the nest then flew off and the pair flew around together. I was able to get some shots of them together. I am only giving this information because I have a shot of the Osprey protecting the nest after chasing the crows away. I thought it an interesting phenomenon.
So, in closing no Osprey at #7923, only crows.
07/14/2019 by CarolC
Linda reports: There was only one Osprey in the Nest that I could see. Right as I got there one flew out of the nest and didn’t come back. I did catch one in flight that may be a juvenile as it seems smaller.
06/14/2019 by CarolC
Linda reports: There were definitely 2 Osprey there and it looks like repairs or some shoring up to the nest was being done. I couldn’t really tell if it was the pair or an adult and a nestling. There is a small head that peaks out, but I can not tell if it is the female or a nestling.
NOTE: We have recorded it as 1 nestling.
05/22/2019 by CarolC
Linda reports: I visited nest #7923 yesterday. I only observed one Osprey of the pair that is usually there, and nothing really going on. No evidence of any Chicks. As you know it is difficult to get decent pictures, but I have attached one for your review.
05/06/2019 by CarolC
Linda reports: I went by Nest #7293 today around 1 PM. Both Osprey were in the nest. One around the rim ( I think the male) and one in the nest keeping low (I think the female). My hope is that she is sitting on eggs. It looked as though they were communicating or feeding although I couldn’t see any kind of food. The pictures attached are not great, but they do show the 2 in the nest. The nest is far from my vantage point so this is the best I could get even set up on a tripod. I also observed them with binoculars, but those observations are the same as the images I have attached.
04/23/2019 by CarolC
Linda reports: I went by Nest #7923 this morning at about 10 am to 10:30 am. I definitely observed 2 Osprey, should be male and female. I think they are sitting on eggs, one (probably the male) venturing off for a little bit and them coming back.
04/03/2019 by CarolC
Observer Linda reports:
I went by Osprey nest #7923 this morning about 9 am. There was no activity. I couldn’t tell if anyone was deep down in the nest as it is a long one. Stayed for a while and watched with binoculars, but unfortunately nothing.
03/14/2019 by CarolC
Tish S found a spot from which this inaccessible nest can be viewed through binoculars and photographed with a long lens.
07/07/2018 by CarolC
This nest was only found because it was pointed out to the person monitoring another nest in this area in early July. The nest is constructed between the poles of a tower that we observed to be active. (when viewed with binocs there were osprey in the nest and one flying in with a fish).
This nest was located well behind the PSD building, beyond their two ponds. It seems to be inaccessible for someone to monitor as it is in the middle of a heavily wooded area with no apparent public access road.
Although the observer report indicates there are chicks in the nest, we are unable to provide data on the nest and are assuming at least one chick.
