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.
Sorry to say that it appears that Amelia and Charles have abandoned their 4027 location.
Last year they had to rebuild 3X due to storm damage. Have seen Ospreys in the same area.
Going to miss them. Will keep monitoring.
I am glad to report that Amelia and Charles have returned to their nesting site. Bad news is that the nest was totally damaged by Hurricane Matthew. Good news is that the two have already started rebuilding their summer home.
Our Ospreys came home 15 March 16 to find their nest totally gone by a winter storm. After 3 days of hard work they completed a new and better, and hopefully stronger, version.
Fishing is terrific here so all is well.
