Congratulations, it’s an Osprey chick!
By Ilana DeBare
Mother’s Day came early on top of the Whirley Crane — with the Osprey pair at the center of our live nest cam hatching their first chick early Friday morning!
Rosie, the mother, was on the nest in the early morning hours as the first of two eggs hatched over a period of about nine hours. When the chick had pecked its way partly out of the shell, she picked up the discarded top half of the shell and tossed it out of the nest.
What was at first only visible as a pink ball hidden deep with in the nest became a limp, squirmy creature… and then an active chick, holding up its head and begging for food. Richmond, the father, flew in with a fish and took part in the first feeding.
Here’s a video clip of the family shortly after hatching:

And here are two photos of the chick during its first feeding, around 12:30 p.m. on Friday:

Golden Gate Bird Alliance launched the live nest cam of the Osprey nest at the end of March. Since then, over 24,000 have visited the nest cam web site at sfbayospreys.org to watch the pair incubate their eggs and prepare to raise a family.
Rosie and Richmond’s first egg was laid on April 1st. Rosie initially laid three eggs, but she removed one from the nest on May 1 after it developed a crack and was no longer viable.
The young Ospreys will spend 50 to 55 days in the nest before they fledge. Both parents will take turns feeding them and attending the nest to warm the chicks and protect them from predators such as eagles and ravens. The biggest potential threats to nestling Ospreys are predation, exposure, and lack of food.
“Rosie and Richmond so far have been terrific parents,” said Cindy Margulis, Executive Director of Golden gate Audubon “They kept the eggs consistently covered and warm, fought off interloping birds, and rebuilt part of the nest when it was damaged during heavy winds. We’re hoping they will be just as good a team when it comes to feeding and tending their chicks.”
While a successful hatch of Osprey eggs may seem routine, that has not always been the case.…
