Nestings at different stages

More screenshots of the Berkeley Peregrines.

Parent sighted!

It was mom Annie, returning home for the night. The chicks are too big to brood, and can thermoregulate, but she sleeps in the nest with them to guard them. As for the nest, unlike eagles, falcons don't really build nests, just dig a shallow spot for the eggs if there's even enough loose dirt at the cliffside - or in urban settings, tall building - that they pick for raising their young. Annie, Grinnell, and their chicks have a human-made nest box to scrape around in, but I've seen falcons in cities even nest on just a bare windowsill.

Parent with food sighted! Much higher priority!

Oh, and looks like banding will be later today for the Peregrine chicks.
ETA: Here's video of the banding. (Content warning for small remains of prey in the nest. And though the banding is done for a good reason the experience is inevitably scary for the wild birds, so if you want to turn up the volume to hear the scientists talking, note that the falcons can get Very Loud when frightened.) And here's live Q&A on the banding and other birb things.

I've also kept an eye on Satakunnan sääkset, a group of Osprey nests under observation in South-Western Finland. There are four nests, out of which at least two are occupied this year, with experienced pair Alma & Ossi having raised young for many years at nest #1, and newer pair Nuppu & Ahti at nest #3. Both nests are currently at incubation stage, with three eggs in each and hatching expected for the end of May (#1) and beginning of June (#3). I look forward to seeing the little osplets.

Most of the site about the Osprey nestcams are in Finnish, but you can find some pretty detailed graphs about the nests' history in English at "Pesinnät", and all of the available cameras are predictably under "Live".

Then some screenshots of the Cornell Redtails. Warning for clear view of prey, some of which are pretty gory, in all of the images.

Big Red in beautiful morning sunshine.

Chick peekaboos.

The chicks snuggling in their cozy pile of corpses while mom is off the nest.

The youngest seems to decide the two older siblings look like a warm, comfy mattress.
