Adult Arrival

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.

Incubation Initiation

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.

Clutch Hatching

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.

Nestling Count

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

Fledgling Count

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.

Nest Failure

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

Even though we couldn't gain access to the property the nest was on, we could always see it from the road. We took photos each Sunday for the past few weeks. This past Sunday, as we drove by we didn't see the nest. I contacted a friend who was able to gain access to the property and he found the nest had been on fire, and he saw three dead chicks on the ground under it. We don't know if it had been struck by lightening, or some other reason. He took photos of the deceased nestlings to show me (very sad).
