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.
We were at Williams Pond to check on Nest 4646 and when we saw an osprey on a lighting fixture, we assumed it was from Nest 1. As it sat up there, another osprey swooped over and took a seat next to it. We still figured it was the Nest 4646 pair. When we drove off, we could then see the pair on the higher fixture, closer to the other nest, so we now know that this pair belongs to Nest 4755 (#2). So, both pairs are back at Williams Pond.
However, this pair from Nest 4755 had a little mating activity going on.
This nest was vacated sooner than the other at the park. We never saw any other activity, other than several ospreys flying overhead, but this park is right beside the river and was very active with overhead activity.
One chick flew into this nest while we were watching the other nest (#4646). It looked like he had a fish. He was sitting up, watching the other nest when we left. There was no other activity in this nest during that time.
We rarely see these chicks in the nest. Yesterday, we were watching the other nest and one flew in this nest with food. He stayed for awhile and then took off again. We have not seen the adults in the nest for quite some time.
We spent awhile checking these 2 nests yesterday, mainly because one chick has fledged from this nest and we were hoping to see it fly back. There were a lot of Osprey in the air, as so many local birds are on the wing now! But we didn't see the one chick return while we were there. The other chick was eating the entire time we watched.
We've driven through the park several times over the past week, but not much activity, other than chicks sitting up with a parent and lots of wing stretching! Tonight, they were all sitting and watching softball. There is a lot going on in Williams Pond Park to keep these 2 nests occupied!
These 2 chicks are growing fast! The mother was fussing at another pair of osprey that were flying around the river, which is right in their back yard, so to speak. At one point, she left the nest, flew around in circles, crying constantly. I first thought we were bothering her, but we were sitting on the bleachers of the ball park, which gets very busy all summer. Plus, there were a couple of youngsters in the field close to her that were practicing batting.
There are, indeed, 2 chicks in this nest!!! I am so excited! This was the first pair to be spotted incubating and they are now the proud parents of 2 chicks! I thought maybe she had chicks, since she was sitting on the edge of the nest the last time. Their heads are now visible over the top of the nest, when I stand up on the bleachers in the ball field. I am going back with my zoom camera to get some photos!
Checking this nest today, the female was sitting up on the edge the whole time I was there. She would look down, moving her head down, at times. This is how I've seen the eagles do on the webcam when there are chicks in the nest, so I am still thinking there may be a chick in this one.
I am going to say there is a chick in this nest. The pair were very busy when I checked this one. The male came in with a fish and left for a few minutes, while the female was ripping off pieces of fish and bending her head over. So I am assuming she was feeding a young one! The male came back pretty quick and I could just barely make out some movement in the nest, between the parents. This was the first of my nests to look as though they were incubating!
I've seen this female sitting up more, but then later she was sitting further down in the nest. I am not hearing any new sounds yet, or seeing any movement through breaks in the nest. Male was eating nearby while we were there.
The female is pretty low in this nest, so it's hard to see her unless she pops her head or tail up. I could just barely see some movement when I checked this nest. The male was not around, even though he usually is in a nearby tree.
Same as with the other nest on this spot, female was in the nest, hunkered down. Male was nowhere around. Softball practice was going on. Personally, I wonder how these 2 pair of ospreys handle raising young in the middle of a youth softball field! :)
I wanted to take a photo of this nest yesterday, but the male is always very close and very watchful, so I had to take it from a distance. The female can be seen looking out over the edge, but I thought I saw something else yesterday, which is why I was hoping to get a better photo.
I feel sorry for this female osprey. Her nesting platform is right in the middle of a couple of little league softball fields. The Williams Pond 1 nest is here, but it's off to the side. This particular nest is in the middle of all of the commotion. The male is always in a nearby tree. Last night, there was also an eagle in the nearby tree.
This nest became very active, very quickly. I've never observed in this manner, so I am not quite sure. But it looks as though this nest may have eggs. The female is usually sitting deep in the nest, to the point of only being able to see her head or the top of her head. The male is usually perched in a nearby tree. He's been very protective. I am going to assume that she is incubating, at this time.
While checking on the Williams Pond 1nest, this one had remained empty. We were checking the 1 nest this weekend and saw that there is now a pair on this platform, as well. The female was sitting in the nest and the male was on a nearby pole. When I opened my car window, he swooped down directly over the car........very close. I've never had that happen. I'm wondering if they have already mated successfully!
