on a new platform placed there 2016. This is possibly the same pair that has unsuccessfully tried to nest around River Barge Park. The nest is about a half of mile from last year's nest in a dead tree on a Redtail Hawk's abandoned nest
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.
Things are well with this nest. This was a late nest and the chick is probably more than a week from fledging. I did get a report earlier in the week that a peregrine was causing distress at the nest, but things look good today. Pic attached
checked the nest this morning, all is well with the single chick. The female is very spooky, flying about and calling even when you are several hundred yards away. And the chick lays low so you can't see him. If you are well hidden for a half hour or so, he comes up.
This nest is on one of several platforms placed around River Barge Park last year. There was a nest on a dead tree across the river from the park, but it fell down. This nest is about a half mile or more from last years nest. The pair started to hang out around the platform at the end of March and now has a nest started. Pic of the birds copulating today
