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.

Upon arrival of the third and final observation of The Great Pillar of Ospreys nest, the nest was active. There was no egg laying, incubation initiation, clutch hatching, nestlings, fledglings, first check fledging, or nest failure. The nest was active. The female was, again, perched on the nest, and the male Osprey was flying near and around the nest. After a few minutes, the male Osprey flew out of site and the female Osprey remained perched on the nest for the remainder of the observation.

01/15/2014 by Gmoney

The second visit to the the Great Pillar of Ospreys, I observed a female Osprey perched on the nest. The female had a light/pale necklace on its breast. This female Osprey didn't leave it's nest. It stayed perched the entire time of observation, and there was no male Osprey in sight.

01/10/2014 by Gmoney

This nest looks abandoned, but may not be. For this first viewing of the nest, there were no Ospreys seen during the time of observation.
