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.
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.
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.
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 fly
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.
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.
Look for signs of nest failure like adult abandonment, adults no longer incubating eggs or feeding young.
Today was able to take a photo of the female incubating eggs. Because of the very high tide I took the photo from Buntings backyard where I was able to look down into the new nest box that Bob, Roger, and I installed. Eggs for Easter...nice!!
After the platform was destroyed by a storm last year, with help from two others, we rebuilt the platform after the osprey had left. The pair have now returned to the new built platform. We hope to see nest building soon.
I have monitored this nest weekly as the pair stayed at the site and repeatedly tried to rebuild the nest. However, every time the branches they had brought soon fell in the river. I am looking for someone with a boat to help me rebuild the platform.
I have monitored this nest weekly. It has been extremely windy and stormy weather all of April and May. This pair rebuilt their partial nests many times only to have it blown away again and again. The platform needs to be rebuilt but a boat is required.
I have observed two osprey returning to the platform frequently. They have begun an attempt to build on the mostly destroyed platform and seem to be making some progress today. The weekend will be windy so I hope their nest holds.
Today there is no activity on the platform which is mostly destroyed. However, this did not stop them last year. Many osprey in the air but who knows what nests they belong to. Nest up the river is occupied and a pair on that platform.
On 7/12 I walked to the river and observed that the chicks from a nearby nest had fledged. The water was high and I was unable to walk to this nest. That evening I went to a parking lot and was able to observe that there were still osprey on the platform of this nest. On 7/14 I went to the river very early while the tide was low so I could walk to the nest. The two very large juveniles were on the platform. A parent flew overhead constantly keeping other osprey and a juvenile eagle away. The chicks were constantly calling for food. Finally the parent landed for a while but did not bring food. These two seem very ready to fledge.
I have observed this nest on a regular basis as the tide has permitted. Activity has been delayed due to the platform being blown away. It has been impressive that the osprey brought in very large branches to build a secure base for the nest. They then built on top of that base and the nest has weathered several wind storms. Today I observed the female sheltering the nest with her wing...probably chicks. Dad was on the rocks below with a large fish.
On Feb 25, 2021, I checked for osprey return. At that date I observed that the platform for this nest is gone (see photo) I wonder if it was removed as it is somewhat close to the marina. There is another platform between the missing one and Rivers Edge 2 , however, no osprey have ever liked it. There was one male hanging out there. Over the next two weeks I checked for activity. This second male seemed to be skirmishing with the male from Rivers Edge 2 but on 3/9 was not around. I did see an osprey on a cone far out in the river....perhaps him??
Today when I first arrived near the nest, the parent and large hatchling were eating. Three kayakers came close and both parent and hatchling flew off. Fledgling is a very strong flyer and flew over head for 3-5 minutes before landing in a tree.
Finally got a great view of this nest...Chick not hiding..both parents were on the nest and the chick was eating. The parents left when they saw me but the chick kept eating and then started flapping its wings.
Today I got a good look at one chick. Dad sat with a fish below nest on rocks but parents are very cautious and after 20 minutes he flew away with the fish. Will continue to try to sneak up to see if more than one chick.
Although the male brought a large fish to the female on the nest, there did not seem to be any feeding behavior. There were people in the area so perhaps that stopped the feeding. Female did not seem to be incubating at this time as sitting much higher so probably hatchlings who are too small to see.
Today I was able to see two osprey on the nest. Foggy and observed from a distance. On the 18th I did not see a pair but now have been told by another watchers that she saw at least one before the 18th. Return date is an estimate.
It has been hard to observe this nest due to the river being high and only able to observe through the scope at a distance. By 6/30 two had fledged and were on the rocks near by. One other fledgling was with Mom on the nest but as boats cam by they would fly from the nest and then both would return. I did not see any feeding.
Last year during a hurricane a tree made it impossible to access the path to the river to monitor the nest. A new trail is now making the river accessible. Today I saw one, possible two chicks being fed by both parents.
Fought my way through the brush along the river to get a closer view of this nest. Two birds on nest, one obviously a hatchling. The other one immediately flew off and I never got a good view of wings to determine age but probably is an adult based on behavior. Appears to be only one chick from this nest.
Observed from a distance that incubation had ceased on 5/18. On this date, due to four days of heavy rain, the beach along the nest was not accessible. My assumption is hatching around the 15th of May. Will continue to monitor
Although seven osprey have been in the area since the first week of March and one osprey has been observed on the platform off and on since that week, it wasn't until today that I was able to get a photo of both birds on the nest. The nest was destroyed by winter storms but at this time has been mostly rebuilt. Due to light and distance, the photo is not great.
Observed female on nest shading a large chick that was well feathered and stretching its little wings. after 30 minutes another little head appeared, a much younger chick that did not stand or stretch.
I have observed this nest on two ocassions..at this time it appears unsuccessful. Today the male was sitting on the edge of the nest. He flew away when he saw me even though I was some distance. After I left he returned and sat on the nest edge. He peered into the nest, and rearranged a stick and then left. There does not seem to be a female around at this time. I will continue to monitor for her.
I have observed this nest on 4/27 when the female was incubating, and on 5/11. On 5/11 the male was sitting on the edge of the nest and the female was very low in the nest. It is difficult to observe the female from any location on land. I will monitor this nest when I do my nearby nest and hope that with my spotting scope I will be able to determine when there are chicks in the nest.
