April 17 notes: two eaglets in our nest!

This morning after a prey delivery (a duck?) we watched the parent eagle feeding two chicks. She meticulously reduced the prey to small morsels and carefully fed both chicks. One chick is older and larger than its sibling and is the first to be fed. The smaller chick will continue to do well as long as plenty of food is available. Sibling competition for food and mortality from starvation or infanticide is greatest in the first two weeks when the size difference between the two chicks is the greatest.

For most of the time, the chicks will remain out of view of the web camera. They cannot maintain their body temperature when they are young and downy. Notice how the parents sit differently on the nest in a more upright posture. On rainy days, the wings of the adult act like an umbrella to keep the chicks dry.

The chicks will remain downy for the next two weeks. At that time, we should start to see some black pin feathers, which will replace the down. If chicks are fed well, they grow about 100 grams per day. Maximum growth occurs when they are about 3 to 4 weeks of age.

For the first two to three weeks after hatching, the female is present at the nest about 90% of the time and the male about 50% of the time (out of view of the camera). You will often hear one of the adults calling to its mate or tilting its head upward to watch its mate soaring overhead. Once the chicks start to grow feathers and can maintain their body temperature, the parents will begin perching off the nest.

Bald eagles are extremely sensitive to disturbance at this critical time. To flush an adult eagle from the nest exposes the chicks to cold, wet weather or predators. When we review development projects, we always request that activity near the nest during the incubation and early chick-rearing period be avoided. -- Mark McCollough, U. S.

Watching the live video, I saw the parent feeding both chicks! I could see the tops of their heads as the parent presented them with the prepared food. This was at 2:25PM ET on Tuesday. Wonderful!

April 20, 2006 I have been watching the live Bald Eagle Webcam since the eggs were in the nest and first noticed one baby eagle, then there were two, and just now at 1 pm, I thought I saw 3 baby eagle heads...has anyone else noticed what appeared to be 3 babies? What a wonderful experience to be able to watch the eagles live!!!! Thank you for this opportunity!! PS I have been sharing this experience with my 7 yr old grandson, and he too enjoys it.

Thank you so much for this website. We had been waiting for the chicks and suspected something had happened around the 12th. It was a wonderful Easter, because when I checked in, I saw something white moving, and then one head and then another pop up. Mom then went to the side of the nest and fed them. It was a wonderful new beginning.

Hi! I've been watching since before the eggs hatched. Yesterday I finally saw two fluffy little heads!
Is the sound no longer working?
I saw a squawk this morning but cannot hear anything.
Thank you for all your hard work and your passion!

I am so thrilled that today I was able to see Mother Eagle feed her three chicks! I missed the drop off of food, but was able to clearly see all three. It did appear that two chicks were feeding quite well and the third may have been a little less 'forward'. Thanks so much for sharing this wonderful experience with the public!

Today 04-22-06 One of my co-workers has reported seen a third chick today.It really created quite a stir.
We have been watching the nest since 04-17-06
We are a group of 911 Dispatchers and watching the nest has become a dailey requirement for us. The day is not complete unless we have seen the chicks
It really creates some excitement when they are being feed. Thank you for all your hard work

Are there two or three chicks? I thought I saw a third little head, and later read on another site that three chicks hatched.

We now see three chicks in the nest. NWF must have played stork recently unless they miscounted the eggs.

I saw the Baby Chick's head popping up yesterday, and there wasn't a parent in sight. Do they leave the chicks alone for long? Are both chicks still there?

I thought I saw the eagle eating something. I guess it was food for the new chick. Great photo of the baby. THis is such a wonderful opportunity for the public to appreciate the delicacies of life in nature.
Thank you for having this available.

P.S.

Thanks to everyone who describes what they see.

My neighbours, who once had an alternate nest in back of their house where they could hear the eagles interact had told me that the male and female talked softly (murmered, they said) and were affectionate with one another.

But I have never seen it. Thank you so much for sharing! I love every detail!! Even though I "live with eagles" I don't get to see what goes on at the nest except for a quick look once in a while with binnoculars. WHen the eaglets are flying around, I DO get to observe them and to know them, and feel that they know me. Or at least I'm familiar.

Are there still three chicks? I have only been able to observe two for the last few days. Did the younger one die?
