Thread subject: Eggs and Warmth
Name Date Message
Mickey 03/04/05 09:17 pm Way back in the first season here I asked if anyone knew what temperature the eggs needed to be kept at to hatch. We`ve all been watching the Eagle cam lately itching for our cam to get up and running. It was written that the female Eagle has under her a "muscle".I forgets its name. And during the roosting season the female and depending on the species the male, sheds the feathers exposing the muscle. The muscle can be close to 100 degrees. It was further written that when you see the adult wiggling to sit on the eggs, its really exposing the muscle and positioning the eggs to keep them ultimately warm.
Nature man! Its unbelievable !
Grace 03/05/05 09:54 am It's called a brood patch....I learned that from the eagle site sometime back. A quite remarkable adaptation. Problem is that a bird's feathers do such a remarkable job of keeping the heat in that were it not for this "patch" the eggs would not be warm, even if the parent was sitting on them as all the heat would be retained by the parent.
