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.
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.
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.
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
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.
Look for signs of nest failure like adult abandonment, adults no longer incubating eggs or feeding young.

Both M and F sitting on the edge of the nest.! Turns out she must just have been stretching since it is warm enough to leave eggs uncovered for a while. She went back in and down after about 15 minutes.
August 10/17/24/31: Observed on Saturdays from deck above resort pool overlooking the James River (no binoculars): 3 osprey fly in and out of a nest on a chimney on one of the guest quarter buildings. White poop all over green roof. ;) They are only a 100 yards from the water, so convenient for bringing a fish home to the dining room table. This nest was not there last year! Could it be the couple from the cell tower relocated to waterfront property?
9/7/13: two osprey observed on chimney nest
9/14/13: no osprey observed, but nest still there If any nests on chimneys appear in 2014, a new nest site will be reported. Stay tuned!
