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.
4/11/23 - (11am until noon) When I arrived to watch, there were just a few sticks on the platform and two crows perched. After a few minutes, the crows flew off and one Osprey perched facing southeast for about 15 minutes. It then flew in a circle around the platform and then again perched. dlm
Since this Wednesday April 5th a number of observers have seen a pair of ospreys inhabiting this nest .. I just took a picture of one of them sitting on the nest platform for a few hours. There really is no nest so far .. maybe just one or two branches sitting on the platform. DH
Have been monitoring for several weeks between 11am and 2 pm. No Osprey activity to date. However, there are lots of tree swallows on the nesting boxes and there were 2 hawks soaring overhead on 3/20. dlm
No activity to report during the first week of March. Two sites were used, one on the north side of Discovery lane in a clearing just past the wooded area as you drive in to CBEC and the other one about 100 yards into the adjacent woods with a clearing at about twice the distance to the platform.
