The generation of an egg and the laying of the egg are very energy consuming for the female eagle. The first outward sign that she is about to lay an egg is pulling the soft nest material up around her at 2:34. Then the process of forcing the egg out can take a few minutes to about a half hour or more. As these photos show she began to concentrate (strain) at 2:46 and the egg was in the nest by 2:49 – only 3 minutes.
