I found two Easter eggs today. Most likely they hatched yesterday, after I left, but lets make Easter their birthday. Bringing the total of hatchlings to four. Mom is spending an hour on the nest taking 10 to 15 minute breaks. When she flies out of the nest she zooms to the opposite side of the river and dives in, pops up on a rock, dips a bit and dives back in; she is in swift water and it carries her down stream, she is swimming against the current, splashing and frolicking about. Not hunting or bathing, it seems she is releasing tension and stress, and just having fun, this goes on for about four or five minutes. She did this three times today, and I saw her do it a couple times yesterday. As soon as she finishes her fun in the river, she finds a spot to get a little something to eat, and then another to bathe, finally she preens herself. Snagging a couple morsels, and takes them back to the nest. Everytime she is going to stay in the nest she makes 2 to 4 food deliveries.
Feedings are happening from three minutes apart to 40 minutes. The male is making many of the feeding runs. When the female comes out he goes in with a bug or two; when she returns, to the nest, he spends the next 10 to 15 minutes making food runs, and then he splits to the second nest. He spends about 10 minutes at the other nest and then he comes back with a mouth full for the kids. During one long feeding break he had gone up stream and took care of himself for 40 minutes, during which the female had come out and gone back in. I think they got together because she went up river to near where he had gone. She returned first, and made two trips into the nest with food, before staying to keep her babies warm. The male showed up a few minutes later and brought everyone a bit to eat. Everytime she goes back into the nest the male makes three or four food deliveries. The nestlings are not eating all that much right now, but that will change in the next couple of days.
She will spend most of her time in the nest, for the next couple of weeks, until her kids have gotten a warm coat of feathers. The feathers will not be complete, they will be still a bit downey before she stops spending most of her time brooding. As days go by during the next two weeks she will be spend more and more time out of the nest, to get food for the hatchlings.
