Nest #6616

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.

Welcome surprise to see the Ospreys have built another nest directly across the street from the previous nest. Will continue to monitor to confirm whether the male is the same leg banded Papa from last year.

This nest was removed within the last week or two. No sign of an Osprey nest on the utility pole remains at this location.

Drove by this morning, after last night's nasty storm. I did not see any birds in the nest, but I did catch a Fledgling sitting on a telephone pole nearby with his own fish! Picture uploaded. Dark and overcast morning, tough to see but clearly this is one of the fledglings from this nest. Will stop by later when the sun comes out to observe further. Fledgling with his own fish is an exciting thing to see!~

Two large nestlings eating while one parent observes from a nearby tree and the other parent was seen chasing an interloper above the nest. Pictures uploaded. In one you can see an adult looking up with interest as the other parent is chasing another Osprey vigorously directly overhead. Quite the airshow.

This evening observed two very healthy nestlings looking like they are ready to fly any moment now. Very hot day, and both were trying to stay cool while the female was standing watch in a high tree nearby. Did not observe the male in the area. Picture uploaded.
