The nest is atop a standard telephone pole being used to mount four large white speakers evidently used for fire department or orher public alarm. It is inside the Union Beach Recycling Center lot and vieweable from Florence Avenue.
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.
I noticed this nest the other day and came back this evening to document it. There was a single fledgling that flew out of the nest and alit on a tall microwave tower on the same muni property. The nest is on top of a cluster of at least five large speakers or horns. I parked in front of the locked gate to the recycling center, but I was too close for the nervous bird's comfort when I emerged from the car to check a street sign and take photos. The youngster perched on a cell tower panel for ten minute watching and waiting for me to leave.
