Nest is on Big Pine Key, FL, located about 50 yards inside a wildlife refuge east of the intersection of Cupon Road and Pine Ave. Nearest home is 924 Pine Ave. Nest is about 1/4 mile north of the SeaCamp education center.
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 has been observed in previous years but not reported. Today there were two birds on the nest. One (male?) left shortly after observations began. The other bird remained on the bird, calling repeatedly, especially when a Turkey Vulture soared nearby. At one point, the foraging bird actively chased a Turkey Vulture from the area. Young were not seen but clearly nest defense was occurring. It is hoped that staff and students at the SeaCamp Education Center will monitor this nest.
