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.
5/5/23 Alot of activity in the Nest, Female in the nest, Male bringing in Fish. I am confident in saying there may be Chicks in the Nest although I can not get a clear view through the lens just yet. Photos updated today.
5/1/23 Severe Weather in the area on 4/30/23, so today we went to check on local nesting sites. At first we didn't see or hear any Osprey here, but within a few minutes the Male appeared and flew directly over the nest, and a chorus of calls came from within the nest. I would be confident in saying the female was definitely in the nest, as well as atleast two chicks. The vocalizations stopped after he flew away from nest, and began again a few minutes later he flew back over the nest. Male was circling and being antagonized by a Fish Crow while in flight.
4/2/23 Nest appears completely built back. Both female & male present in the nest.Can not see in the nest, but two Crows were flying around and at one point tried to land on tower. Female took to flight while we were observing. Photos uploaded of today.
3/11/23 - Went by to see if nest was being rebuilt as it was removed in Feb. 2023.
I didn't see signs of rebuild at that time. As of today's re-check, Nest is well under way being re-built. Witness Osprey on the tower, nest; however by the time I got safely parked, they flew off and I didn't get to get photo. Will return to check this site.
