What to look for
a
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.b
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.c
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.d
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 flye
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.f
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.x
Nest Failure
Look for signs of nest failure like adult abandonment, adults no longer incubating eggs or feeding young.Review All Observations

We were out for the day on a trip to Forsythe and when we left home, everything was as always on the nest, mom sitting down deep with just the top of her head showing. When we got home, mom was in a dead tree in our yard and a crow was walking around in the nest. Mom continued to sit in the tree and do some very odd wing displays, like a baby bird fluttering for food, she seemed to look sad to us. After about an hour she went back to the nest, looking into the bowl and then she would flutter some more and go out to the perch. She has not sat inside the nest since and continues to leave for linger lengths of time, but always comes back.
Now we are not sure if there never were eggs, or if something happened to the eggs.

On April 20, we observed some behaviors that we thought might indicate there were eggs being laid. After that, someone was always on the nest until the weather warmed considerably. Then mom would take short breaks out on the perch.

The platform was replaced on March 22, thanks to Ben Wurst and some great volunteers. The female returned to the nest on March 29, and the male on March 31. They are both on the nest, there have been several sky dancing courtship displays and mating today.....several other Osprey have been around the nest, but the pair chases them off.

The nest was checked early in the fall and showed signs of raccoons scratching on the platform and pole. We are looking for volunteers to come on November 15,2014 at 10:00 a.m to construct a new platform with a predator guard. Then pole was damaged by hurricane Sandy.

Nest either needs to be replaced or it needs a much better predator guard. Hard to tell if predation is from ground (raccoon) or aerial predators (owls).

We actually purchased this home because of the osprey nest!!!! There were two adults on the nest all summer, no young, wondering if these are an immature pair. Also had helicopter activity off and on, checking for Mosquitos, not sure if this was disruptive to osprey activity. They left about two weeks ago....
