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

7:15 AM 4 osprey were on on the tower. Two adults, one juvenile eating a fish and one juvenile begging from near the nest. So it looks like two fledges.

Nest remains active. One adult appeared to be feeding at the nest this morning around 7:15 am. I have still not been able to spot chick or chicks. Yesterday, both adults were on the tower though not actually on the nest at about the same time.

Nest remains active--one osprey was sitting on or near the nest in the morning. Nest is too high up to see chicks, but presumably they have chicks since they remain at the nest.

4/5/22. One osprey was flying low over parking lots around Ocean Blvd apparently looking for nesting materials. It flew back up to the radio tower. A second osprey arrive within about a minute with a fish and joined the other at the nest on the tower.
