The nest is in housing on the top of a tall fixed crane on a barge that is just north of Veterans Memorial Bridge in Chesapeake, VA.
What to look for
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.
The nest isn't active anymore. What had been a fairly level substrate was raised, the nesting material fell out or was removed, and wires were stretched across the entire area to prevent renesting. Pretty amazing. I'm fairly certain no eggs had been laid. There are a few empty channel markers with platforms just downriver. Perhaps the pair will relocate to one of those. We'll keep our fingers crossed.
I discovered the nest while driving south over the bridge on 3/30. It was obvious there was a nest on the crane that was just to the north of the bridge. I've since been back twice to photograph. The crane is inactive.
