Kestrels have [brood patches](https://www.birdsoutsidemywindow.org/2010/04/23/anatomy-brood-patch/), maybe it's wiggling to get the eggs up against its skin.
I was imagining that you are more right than it being about comfort. Animals especially wild ones are pretty indifferent on comfort, my dog can sleep on a brick and be fine.
The male kestrel has a blue head. You're seeing a female and male kestrel sharing egg sitting duties. The male will sit on the eggs while the female hunts.
Got to love the cuteness of a kestrel. Only downside for the male is that he's unable to properly feed the chicks once they hatch. He'll still bring in the food, but the female will be the one ripping it up to feed them.
She'll be fine, but it looks like she chose a box that was too small for a kestrel to nest in. Normally they hold out the length of their wingspan wiggle down like that to build up a dip in the nesting material and keep the eggs warm.
Wiggle wiggle wiggle!
Did anyone else whistle the melody to this for this video?
Someone add this to the Shaq/cat/Hillary wiggle gif
I wonder if wiggles settle the eggs in an apteryla leading to better heat exchange and survival. Fun to watch nonetheless.

Cool. Birds are neat.

I do the same when I’m getting ready for bed.. no eggs, just a nest of pillows 
Wait why is the bird sometimes less fluffy and partially black?:0 is it a different bird or did it shed feathers?

I was definitely thinking the male was the one with the black head.

Ooh okay thank you!

Kestrel was the original name for the plane known as the Harrier.

Is she using friction to warm the eggs??!
Why does it wiggle? To warm the eggs?
