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

Been by a few times and the nest doesnt look like it's been refreshed and havent seen anyone in it.
03/27/2023 by lost_bird
Saw one bird settling in on the nest, likely arrived several days ago but this was the first sighting.
03/18/2023 by saphyress
The nest from last year is falling over and looks like a fire hazard. I am letting the Wareham DNR and Eversource know.
05/30/2022 by saphyress
Consistently seeing both birds in this nest and one across the water. Today all four birds were actively flying around.
07/22/2021 by lost_bird
Got a photo of two chicks (plus mom) in the nest today, not sure whether they have fledged.
05/14/2021 by lost_bird
The female has definitely been incubating for several weeks now, though can't give a specific date.
04/23/2021 by lost_bird
The nest is in good shape and saw an osprey flying around but could not see whether the female was in the nest or not.
04/06/2021 by lost_bird
Nest building is definitely progressing though have not yet seen both ospreys on the nest.
04/03/2021 by saphyress
Pretty sure saw this same osprey at the top of a tree down on the Great Neck paths. This one was sitting around and flew off after a few minutes, the nest directly across is occupied by one bird as well.
03/31/2021 by lost_bird
Saw a nest in progress and one bird on it, though he was flying around a lot too It's a tough spot to build plus another nest just across the water.
04/19/2020 by lost_bird
There are some nest materials on the pole but not much yet so the ospreys can't have been there long. At least 5 other ospreys and 1 eagle spotted in the area.
04/12/2020 by lost_bird
Several ospreys in the area but not looking like this site will be in use for a nest this year.
