The incubation process began on March 24th when the first egg was laid. The second egg was laid March 26th and the third, March 29th. Bea will take on most of the responsibility of incubation, seldom leaving her eggs except to feed. Jasper will then take over incubation until Bea returns. Incubation takes anywhere from five to six weeks.

When it's time for the osprey chicks to hatch, the first chick has a definite advantage over its siblings which hatch a day or two later.  The first chick grows quickly and most likely will dominate the nest.  If the food supply is low, the dominant first chick can seize the available food supply to the danger of the smaller siblings. This insures that at least one of the year’s brood might survive. Some of the sibling rivalry can be a bit intense as they all try to receive food from their parent.

The waiting has begun!! Let's all hope for a plentiful bounty of fish so that agression will be at a minimum.

I agree, Mary Pat. It's hard to watch that aggression take place. The Richmond, VA, Bald Eagle nest has two eaglets, and the younger of the two really seemed to suffer a bit in the beginning. I read that the adults were not able to bring in enough food. The siblings are getting stronger and, according to the blog, the smaller one is "getting feistier."

Vivian,
I check in on the Richmond eaglets regularly and they both seem to be thriving which is a good thing. Lots of osprey arriving everywhere. I so enjoy this time year. Still no eggs at Norfolk but oh what drama. It has been a real learning experience.

Mary Pat,

Lots of excitement and pictures for next year's Norfolk calendar! And very different. Can't imagine that there will be eggs/eaglets this year, but it will be fun if there are. It truly has been a learning experience even for those who keep track of and research Bald Eagle nests. Bea and Jasper seem to be right on track, and I believe the nest looks much better than last year.

Vivian,

We agree that this year's nest looks much better than last year's. It seemed to come together at the last second.

Where is the 2012 osprey gallery? I can only get the 2011 gallery.

The 2012 gallery is still a work in progress. We hope to have it open soon.
