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.
The female flew up to the nest as I pulled up to watch. She was carrying some twigs but didn't seem to build the nest with them. At least four ospreys were in the nest and the chicks are starting to look like adults.
Only saw one chick and one adult in the nest. A few other Ospreys were seen and heard in the area, but I couldn't determine if one was the mate. The one in the nest was very observant to those who came too close.
Female was in the nest with some non-parrot birds using the space below. Female was bothered when they flew too close. After a while her mate returned and there was another male flying in the area. Chicks started standing up and looking around towards the end.
Female was on nearby tree, the male was lying low in the nest. There may be a a squirrel nest build underneath but attached to the osprey nest; there were three squirrels present and were disappearing into parts of the nest.
Nest is still occupied by the same pair. The large female was alone in the nest, however every 10 minutes she would leave the nest, fly a circle, and return to the nest. Like clockwork. When she sits in the nest, she is not visible at all from below, it was only when she flew that I knew of her presence. This could indicate that she is incubating being that her trips out of the nest were incredibly short, and very few and far between.
Large nest, well built. Male and female both present nearby nest. Clearly residents of the nest, the female flew in and out of the nest while the male sat nearby feeding on an unidentifiable object. No sign of incubation, however potential is there.
Again the birds were not in the nest but the male and female were both perched. I feel that they were observing the golfers that were golfing off to the side of the nest. It seemed like they were on the look out so nothing bothers the nest. But they were still not doing any mating things.
There were no birds in the actual nests but their was a perched female osprey on the tree to the right of the nest. She looked like she was just checking out the nest to see if she wants to nest there.
