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.
Male was in air "acrobatics" with three Crow when I arrived, both he and I assume the Female who was sitting in the nest were very vocal. He flew around dipping & diving with Crow behind him, and went the direction of the Atlantic with the Crow on his heels when I lost sight of him. Female never left nest. Photo updated.
I had heard and seen Osprey in this immediate area over the last month, but could not locate the nest until today when I saw a Male fly in with fish. The nest is very hard to see as it is very "hidden" in the cell tower, but upon getting out my lens I was able to confirm the nest, with most likely female in the nest, and Male with fish. Uploaded photos of today's visit.
