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.
This nest tends to have nesting materials falling out of one side. Female was observed yesterday moving nesting materials around and branches and sticks were hanging out. Today I observed that the female was settled deeply in the nest and there wasn't any extras hanging over the side. There was a pile of sticks on the ground at the base of the pole beneath the nest.
Very active nest. Observe both adults sunning themselves on the nest. They call to each other often. Another adult cam be heard answering their calls. Possibly from nest 4703. Observed one flying off and the other resettling back into the nest.
about 1:00pm, drizzly overcast day. about 67 degrees. observed female fussing with the nest. possibly moving the eggs.
observed 2 osprey flying overhead and going into 2 directions. possibly males from #4702 and #4703
this was the second nesting site on the road. The nesting pair built on a utility pole. The over hanging branches caused a fire on 4/01/07 destroying the nest and chicks. A second nest was started and also arced the wires. FPL was called and they placed a nesting platform above the wires.
