This nest was not reported until July 2019. It is located in Sea Pines Plantation on Hilton Head. It is on the right side of beach walk 23 behind the house 3 South Beach Lane ( second house on left going
north to south).
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.
Jack C reports: On both dates (6-13 and 6-22) there was not any apparent activity on 7633. There was an osprey in the same tree as the nest for about 5-10 days after I thought the eggs were laid but after that he moved further from the nest and I only saw him intermittently in the vicinity. A lot of activity there today with one delivering a fish and the other standing on the side of the nest so maybe the eggs hatched.
Jack C reports: Two osprey making a lot of noise visited the nest 7633 daily last week. One day they brought a plastic bag for the nest. They took residence 5/28. I'm pretty sure the female laid the eggs 5/29. Male has been dutifully standing by watching nest since then.
Jack C reports: Nest 7633 two osprey circled on 3/19. For the next 5 days one of them landed on the nest and the other one circled and flew around squawking continuously but would not come to the nest. After about twenty minutes of this they both left. On 3/25 they were both on the nest and one of them dropped something onto it maybe a stick, maybe a fish. I didn't see them yesterday or today
