What to look for

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.

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.

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.

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 fly

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.

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.

Nest Failure

Look for signs of nest failure like adult abandonment, adults no longer incubating eggs or feeding young.

The nest appeared much more built-up than last time, and there were two birds observed either both on the nest, or one in the nest and one perched on a nearby branch.

04/17/2023 by lost_bird

The female appears to be incubating.

04/09/2023 by lost_bird

A new nest is under construction in the same tree as the one last year that was blown off. Observed one osprey on the nest who must have arrived in the past week or so.

07/30/2022 by lost_bird

Sorry to report that the nest must have blown down since the last time we were there about 3 weeks ago. Not sure how many chicks were there or whether any survived. Two birds were seen in the tree today where the nest used to be (per photo), and a 3rd osprey flying nearby.

07/09/2022 by lost_bird

Could not get a clear photo but looked like the female was tending to at least one chick in the nest.

05/05/2022 by lost_bird

Saw the male in a tree eating a fish, then he delivered it to the nearby nest (see pics).

04/06/2022 by lost_bird

Saw both birds on the nest yesterday, also another male in the vicinity.

09/26/2021 by lost_bird

Saw two ospreys there on Sept. 17

05/23/2021 by lost_bird

Saw the female on the nest and the male wading in the water for a while before returning to the nest.

04/24/2021 by lost_bird

Haven't been there for about 3 weeks, and in the meantime the birds have arrived, set up the nest, and the female is incubating!

No nest activity or osprey sightings yet.
