Description
There is a metal structure going over the road that holds lights (mostly). The nest is built on top on one of the corners.
What to look for
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.
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.
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.
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 fly
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.
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.
Nest Failure
Look for signs of nest failure like adult abandonment, adults no longer incubating eggs or feeding young.

Nesting Diaries
Every day, I cross the Coleman Bridge on my way to work. And every Spring/Summer I see this nest and it makes me smile! So I finally decided to do a little research about it and that's how I found this watch! This morning at about 7:30, I saw 2 adults in the nest :)
On my way to Gloucester and I saw osprey in the nest. I was not sure if there were any chicks. Too bad that I couldn't stop in the middle of the bridge and took some pictures.
Nest complete, two adults present.
Two adults present, one with nest material in its mouth.
