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.
Female appears to be in the nest, but the male showed up half-way through observations with what appeared to be a little bluegill fish. After sharing at the nest, he flew to the tree and ate the rest of the fish.
Two adult ospreys (& babies?) interacting in the nest. Male flew to tree after some time and finished a small fish. Vocalizations were many at first, but both were quiet near end of observation period.
No nest present, but slight accumulation of twigs on top of platform. One adult female perched in tree roughly 100-150 feet away from platform. On adult male flying in vicinity of platform before perching in tree roughly 50 feet away from platform.
During this third observation of the front gate nest, The male and female osprey were perched on the nest. The male flew off the nest and soared around the pond, but would come back and perch again on the nest with the female. The male did this several times. The male would also perch on other power lines or poles in the area. The female left only twice but for a very short period of time, and then returned to perch on its nest again. The female had a beautiful light grey and white breasted necklace.
During this second observation of the Eckerd College Front Gate Pond Osprey nest, we spotted a female perched on the nest. All she did was look around, and she never left her nest the entire duration of the observation.
This nest is isolated from other trees and is located beside the Eckerd college front gate pond. This pond has a lot of other bird species that can be a good resource of the Ospreys. During this first observation there were no Ospreys perched on the nest. We only saw a male Osprey flying around in the general vicinity.
