Nest #8610

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.

Huge day in Osprey news. I was worried because I had seen only one adult on the nest all day. While I was watching, the female flew in, the male grabbed quick mating and flew away. After shaking out her feathers, she then regurgitated food and fed some chicks. So far I cannot see them nor count them. Still windy but sunny today.

The wind continues to be relentless. I do not see any additional heads, despite now viewing from a telescope. I've tried for pictures but they are just too far away. May have a deep freeze to night.

The parents are getting pounded by the winds and the spray from the waves. One of the pair is always on the nest and I observe hearty eating of fish.

High winds all weekend and it blew their nest away! Rebuilding has begun!

Today I saw the bigger (female?) of the two eating a fish while perched on top of a pole of my pier at 9377 Glass Road. I could see the osprey on the nest also tearing off pieces of food (presumably a fish) while in the nest. Going to try to get a photo today.
