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

9:10 a.m. Once again there was an adult on the nest. It seemed to have brown spots on its breast which would indicate that it was the female. It was calling persistently and I saw at least 4-5 vultures circling overhead. One flew by the nest rather closely as seen blurred in the photo. I am not sure that is what had the osprey aggitated. Usually eagles and osprey just ignore vultures. From the photo it looks as though this bird that flew close to the nest may have been a crow or raven though. I did not get a good look at it as I took photos, but my impression at the time was that it was one of the circling vultures.

1:55 p.m. Today there was an adult sitting on the nest. I would guess this is a new pair, or at least a pair with a new nest location. They have continued to hang around the area after building a large nest, but had no eggs this season. It will be interesting to see what happens here next season.
We have observed a similar situation at the Three Bridges Eagle Nest Platform on the high tension tower. At Three Bridges an osprey pair also built up a stick nest and have been at the nest and in the area all summer but laid no eggs. Next season it will be interesting to see if the eagle pair returns, or the osprey pair remains at the Three Bridges platform.

12:20 p.m. I saw no osprey. It appears that after building a nice nest, this pair has failed to lay eggs this year. I hope they return and are productive next year. I wonder if this is the displaced pair from a mile south which had nested on Smiths Diary silo in 2020.

4:20 p.m. From the Warren Glen Rd, across from the tower, I saw no adults on the nest.

1:45 p.m. I saw one adult on the post above the nest which flew off before I got my equipment set up after parking in the access road off route 519. No other adult was on the nest.

10:40 a.m. As I was driving from the Warren Glen tower nest, heading toward 519 north to check the Quarry nest, I saw a huge pile of nesting sticks on a tower at the intersection of route 519 north and the Warren Glen-Bloomsbury Rd northeast! I continued straight (northeast) not turning left onto route 519 and found a view of this tower across from a private home. I could get about halfway off the road and watched for quite a while. There was one adult which appeared to be sitting low on the nest. I couldn't tell if it was incubating, but it had a "necklace", so I assumed it was the female. Another flew in with an all-white breast which must have been the mate, a male. The first adult, the female, stood. The pair did a lot of nest-building/stick moving for a minute or so before the female flew off. The male continued to look at the bottom of the nest, move and rearrange, and then sat down where the female had been. Was this an incubation exchange? The female returned after a few minutes and stood wing flapping and moving around while the male stood, then wiggled down again. I presume there are eggs but will have to watch for longer periods. I then turned around and heading northwest up 519 to a driveway with a locked gate--the access road to the powerline towers. From that pull in I got a safe, good view off the roadway. This site is not very far (maybe a mile?) from Smith's Dairy, where nest #7924 was cleared away after the 2020 season, and a great horned owl model was installed to chase away the pair! This might be where they moved.
