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.
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.
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.
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
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.
Look for signs of nest failure like adult abandonment, adults no longer incubating eggs or feeding young.
The male was eating on the nearby light post, the female was in the nest. Another was circling in the area, might belong to a nearby nest. Jerry, a local resident, says that the ospreys tear down the nest and rebuild it each year.
Osprey was again sighted, due to size and visuals it is most likely a female, as she appears quite large and some spotting can be made out. It is unclear whether she has claimed this nest for good due to unclear observation periods.
Osprey from last week was not sighted during latest observation time, although there appeared to be some fish remains nearby due to a noticeable smell near the nest. Nest remains in decent shape and size.
One osprey (gender unknown) was seen perched on the rim of the nest, the first sign of activity since 05/16. Unclear as to whether osprey is beginning nesting, as no mate was seen or heard. The pine the nest is located is by far the tallest structure in the area, and the area itself is gated off, so it may not been a bad place for the osprey to settle.
