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
One in nest down low, very hard to see and one standing watch on pole nearby!
This nest has started later that Hamilton1 and Swift1, but the nest looks like the osprey have been working on it and it finally looks like it is in great shape. Lets hope egg laying starts soon!
Finally the 2nd Osprey has arrived, and nest is occupied by 2 adults!!!
1 Adult was seen at 2 separate times, nest improvements have been made
Nest is still empty and in disrepair.
