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.
One was lying low in the nest. It was moving a bit towards the end but mostly just incubating. There was a male where the missing nest used to be, couldn't tell which nest it belonged to. A green parrot was on the underside of the nest before departing.
The male and female were both in the nest, preoccupied with something in it. Potential for chicks in the nest but couldn't see.
There were also 5 other ospreys in the area flying around this nest and #1218. I think there is at least one other nest on Coquina Key.
The female was fixing something in the nest for a few minutes. The male flew off and after that the female went back to incubating. There was a green parrot building part of the nest underneath before going inside the bottom of the nest.
Pair of osprey seen in the immediate area, however believed to inhabit 1218. Very large nest with blue bag stuck into it. Nest appears to be inhabited by wrens, at least 6. They can be heard chirping and stay close to the nest.
Today I found the nest for the first time. It is very close to another osprey nest. This nest is currently occupied. I saw a male osprey in this nest perched above on a metal pole that stuck out from atop the nest. It was making loud noises while looking around the area. There were more high pitched noises coming from inside of the nest. I did not see any movement coming from inside of the nest.
Found the nest for the first time today. Very easy to spot. There was a male perched up over nest. Heard squawking noises coming from male. Could possibly be from inside the nest (hatchlings) did not see any young.
For my first nest observed at Coquina Key Park, there were no osprey's in the nest, but one couple that perched across it on a light pole with no nest. There were two total nests at that location. The first week the smaller nest was occupied by the osprey pair, and my nest, the sturdier one was not occupied. The second week the osprey's moved to my observed nest and was seen bringing branches and items to build the nest to be a little bigger. The other nest was not occupied by the osprey pair, but was being used by mock parakeets. This week, they seemed to abandon that nest and go to mine and now there is a nest for monk parakeets in my osprey nest. The monk parakeets seem to be fighting and warning of the European starling.
