Some birds do the rationing
Some birds do the rationing in an even harder way- like throwing the younger chick off the nest. Without making any moral judgment here, sometimes it shows IMO that they come from reptiles( dinos). Mammals generally do not do this, or at least not in such a harsh and open form. But of course, it's about the survival and every specie uses it's own techniques..
It's not a behavior limited
It's not a behavior limited to just birds, actually :) Favoring bigger and stronger offspring over weaker ones is a common litter-rearing behavior across all animals, including many species of mammals. In the wild, it is often rare for an entire litter of offspring of any animal to survive to independence. It's a way of ensuring one's resources are used effectively when said resources are limited.
After all, mammals are also descended from reptiles :)
There are other strategies apparent in birds as well - such as those who devote all their energy into carefully tending one offspring, which is a strategy similar to many ape and monkey species. It all varies!
Also whales or elephants.
Also whales or elephants. Harpy eagles have only one chick and it stays in the nest for a year!

The wing feathers are
The wing feathers are starting to come in and the Kestrel Kids are preening! I love it.
I think the only way to tell if a chick is starving would be if each baby bird had distinguishing marks. I'm going to think positive that all five nestlings are healthy and that they get tired from time to time, just like last year.
I suspect that the babies are getting used to the air and the climate because the parents leave the box from time to time for several minutes at a time.
Indeed, I see a cycle of
Indeed, I see a cycle of different chicks taking a nap during different feeding times. In any case, size differences really only become apparent as the feathers grow in, so it's hard to say so far!
True. But the mom still tried
True. But the mom still tried to keep them warm during the last night. And they need more and more food, so both parents are really busy. The only thing what would worry me are the magpies, if they come when the mom is gone the babies are toast.

It's like the female kestrel
It's like the female kestrel practically floats alongside or on top of some very strong, lively chicks. Again I notice the wing feather tracts.

Thanks!
Thanks!
A dead rodent [vole I think]
A dead rodent [vole I think] was left in the box by one of the parents and one chick has been vigorously trying to consume it on its own. A bit too much for it still, but I am sure the mom will come back soon to portion it for them.
Edit: Mom came, she didn't portion the left-behind rodent, but she did have another for them.
Gosh.!v Just saw a magpie
Gosh.!v Just saw a magpie flying by! Fortunately did not stop at the box.

Parents now leave for sometimes more than half an hour. I guess they have to feed themselves a bit.

The chicks are beginning to be able to thermoregulate on their own, and the warmer temperatures definitely don't hurt either. Soon, both parents will be hunting full time to feed the brood.
What are all the dark "beads"
What are all the dark "beads" in the nest? Are those pellets?
Indeed they are! Diurnal
Indeed they are! Diurnal birds of prey can digest bone, but they cannot digest fur. So, they cough up fur (and sometimes hard bits of insect shell) as pellets.
Thank you. So interesting!
Thank you. So interesting!
Sorry - this is not a reply,
Sorry - this is not a reply, but I don;t know how to create a new post! I have just watched a feeding session, from beginning to end. The female kestrel brought in a rodent, I think. It is interesting, in light of concerns expressed about full-clutch survival, that the prey was torn into 32 mouthfuls. One chick was given 30 of those, another got 2 and the other 3 chicks nothing at all. That said, the other 3 were not begging ad may have been sated by a previous feed. Just thought this was interesting to note.
So interesting, your
So interesting, your observations. I just watched the male deliver something to the female, who came out of the box to retrieve it (a rodent I'm guessing). Then she whipped back in to the box, and those chicks had that thing dispatched in no time. I think one chick was given an extra big morsel, and it had that characteristic gagging movement to get the hunk down. Then the female went back to brooding. I'm noticing that the female, although challenged now about covering all the chicks who are getting so big and are more active as well, usually has her back to the entry--like a wind shield. Her tail is blowing straight up vertically. Maybe the position is just coincidental .
yes. :)
yes. :)

For some reason the streaming software we're using is crashing occasionally. We're looking at crash logs to see what is going on. Feel free to report outages - I monitor the cams as much as possible to keep them running, but I am only one set of eyes :)

8:37 AM Boise time, I saw the female go back to mantle her chicks and I noticed she was preening them for a few minutes before she settled down. Really all five Kestrel Kids are so big and strong by now it's like their mom is in a mosh pit. Love it!!!!!
Mantle. Great verb. Is it
Mantle. Great verb. Is it specific to bird observation?
It is! "Mantling" describes
It is! "Mantling" describes the behavior when a bird spreads its wings over something to shield it from view or protect it. It's a behavior raptors do when they are trying to hide their prey from prying eyes, or when shielding chicks. Below is a picture of a red-tailed hawk mantling while it munches on lunch.
Thank you, Shauna! This
Thank you, Shauna! This usage is definitely not original; I heard a kestrel rehabber (whose actual success I wonder about in the end) use the term to describe how young birds spread their little wings when feeding or trying to eat on their own, as if to 'own ' their meal. So I guess it's very much a birdie term.
Something fuzzy at the top
Something fuzzy at the top near the camera?
Yup, the baby kestrels have
Yup, the baby kestrels have entered the "rocket butt" phase. Birds of prey forcefully squirt fecal material as far away from their bodies as they can, which is why kestrel nest boxes get painted white. As you can see....it can hit the camera, despite the camera being 16 inches up. Luckily the view is not blocked, so we'll just clean the lens when it's time to band the chicks.
As a note, the high ammonia content in the feces prevents a lot of negative bacterial growth, though some more benign bacteria can break it all down. Small insects also scavenge in nest boxes, but they are not a species that is harmful to kestrel chicks. It certainly becomes a weird little ecosystem in there!

The chicks are so pretty at this stage!
I will take note of their tiny tail feathers as they grow in now so I can speculate on how many males and how many females have been growing up. It is so cute when their little tails bob up and down.
From my quick glimpse into
From my quick glimpse into the box, I can tell you one is definitely female! I didn't dawdle to get a good look at the others, though. Soon, their tails will tell is :)
Wait...you can tell the sex
Wait...you can tell the sex by their tail feathers?!
Hi, Diane - I am far from
Hi, Diane - I am far from expert but I will make educated guesses based on any sign of either a solid bar at the end of a tiny tail or of more than one faint one. There is a guide to baby kestrels here in the Partnership Documents on the American Kestrel Partnership site that shows the gradual growth of plumage and field markings. Look for a "Kestrel Nestling Aging Guide".

They must itch like crazy with all those feathers coming in.

Thanks, Jill! I will check
Thanks, Jill! I will check it out.
Yup, just like Jill said - in
Yup, just like Jill said - in this top-down view this nest cam gets, it is often easiest to begin telling sexes early on when the tail feathers begin to grow in. Brownish and stripy = female, and white-tipped with a big black band = male! I find myself peering at the tails now to figure out which chick is what.
If you have trouble telling this early on - worry not, the sex differences will only become more apparent over time :)
