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.
Nest does not appear larger or smaller than last observation, and male was again seen perched nearby. No female in sight, and male spent whole observation period sitting still and occasionally preening himself.
Single osprey was sighted in the immediate area, male and not very large. Was seen perched in the same place as from prior observation. The small nest does not appear to have grown. The male may still have another nest nearby.
No nest visibly present, one osprey, male, was sighted presumably where nest may have been. No viable nesting material could be seen, however osprey seemed possessive of the perch. Osprey did not leave the perch for the duration of the observation period.
Nest medium sized and maintained. Not as much trash in nest as previous weeks. Both adult ospreys present in nest. Both male and female. Another male swooped in and tried to land in nest but male in nest chased him up and they both flew off.
There was a male osprey perched on top of the light pole across the field. Though I couldn't see very well whether the nest was occupied I'm pretty sure I could hear a response coming from the nest each time the male osprey spoke.
The elementary light pole one on the soccer field had the osprey sitting in it, potentially incubating. There was just one osprey located in the nest, but I do not remember if I saw another osprey nearby on another pole. This nest has not changed much.
This week the nest in coquina park was quite eventful. The osprey pair switches to my nest! I saw one osprey, probaby the male bringing branches and spanish moss back to the nest where the other osprey was perched waiting. I do not know which osprey started building the nest but there wings helped them put the nest together.
