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

Nesting Diaries

observer Mary Ellen H reports: one osprey near the nest site. A platform has been requested and may be installed by the homeowners association.
07/02/2018 by CarolC
observer Mary Ellen H. has checked the nest often during June and concludes that for some reason, the nest has failed. While the adults are sometimes around the nest, there have been no chicks. If the eggs were viable, they would have hatched well before July 2nd.

observer reports: One flew away just as I was approaching. Neighbors have seen two together in area.
05/05/2018 by CarolC

04/18/2018 by CarolC
observer notes: Both osprey are at the nest.
Behavior has been very erratic, to say the least, so I will keep looking.
04/05/2018 by CarolC
