More Observations Requested
Now as many of you observed, the bird did make motions like it was tending to an egg this morning. It stood up, looked down, appeared to adjust something underneath it and then settled back down. I looked through today’s images and it appeared that the bird had made several of these type of motions this morning. Since we cannot see into the nest we must be guided by the bird’s behavior.
Eagles like all birds, must rotate eggs to keep them viable and they will do this at a somewhat regular intervals. I would not expect for the birds do this type of motion if they were only “practicing” incubation as they would in pre-laying behavior.
I am hoping that as a group you can comment on the time and perhaps capture video of this “egg tending” behavior. If some of the viewers who are watching throughout the day could actually keep a running log of this behavior (time, date), it would help us determine what may be happening in the nest. This should occur once ever 1-3 hours. Below are a series of picture of the type of behavior I am describing.
Also note if the birds leave the nest for any length of time.
