Family on the Way

On April 4th we received the good news from Colleen Sorbera, National Park Service Ranger at Gateway National Recreation Area’s Jamaica Bay Wildlife Refuge that Coley’s mate was in an incubation position on the nest. On April 6th, Ranger Sorbera gave us this report:

We watched the nest for two hours today. Coley gave the female two breaks and incubated while she flew off to the marsh. He also brought her fish and nesting material. He spent a bit of time preening around the harness and pack. It was a very windy day so some of that could have been from feathers ruffled from the wind. He seemed to be flying strong.

All of this is a clear indication that Coley and family are in good shape and that egg laying happened about two weeks after Coley arrived home. Also, from Coley’s movements since the end of March, it appears that the fish have arrived (or at least are available) and that Coley does not have to leave Jamaica Bay or the immediate area around the nest to find food. All very good news!!!

Still no evidence that the loose backpack transmitter strap is giving Coley any trouble. Next report in about a week unless something unusual happens around the nest.

Coley and Dr. Bob Signing off.

  1. Bob:
    How long does it take for the egg to go from fertilization to maturity?

    • Hi Dolores. 35 days is the usual incubation period for Ospreys.

  2. Good news all around. Eggs laid both on nests on Jamaica Bay and Long Beach Island in New Jersey. This is very exciting. Congratulations to both sets of parents. Madelyn

  3. It’s been almost two weeks since a report. Nothing happening?
