Lisa, Hatching must be getting really close. HM looks disturbed at the eggs. I think they are talking to her or moving inside the eggs enough that she can feel it. Somebody on the chat mentioned an internal pip up to 72 hours before the pip that we can see. Maybe that has happened for the older egg. I'm ready, that's for sure!
HM returned and moved a branchy stick around at 12:30, and HD left.HD ate a fish on the T1 branch later this afternoon. That spot seems to be a favorite of his for perching, holding nest materials, eating, and hanging out with HM.
