Nest #7664

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.

This nest listing, #7664, should DEFINITELY BE REMOVED from Osprey Watch. It is superimposed in the same location as nest #6887. THERE IS ONLY ONE TOWER IN THIS LOCATION AND ONLY ONE NEST. Having two redundant listings has the potential of splitting up any observations and cause confusion among any observers. Besides myself, there is one other person who regularly watches the pair at nest #6887 and we both report on the page for this nest number.

This site is redundant and should be eliminated. Nest 6887 is active, followed and in the exact same location...there is ONLY ONE TOWER IN THIS SITE!

This is a redundant listing. See tower #6887 for reports on active nest in 2020. There is only one tower in this area although two are noted on the map, very close together. The ONE TOWER near these GPS coordinates and pictured in the 2019 photo is behind the Hardwick Township Municipal building as described on the page for Nest #6887. My reports are found there. This entry/tower/nest #7664 should be eliminated as it duplicated the tower/nest #6887.
