American Kestrel babies hoping I was mommy

I monitor a couple of American Kestrel next boxes in south-central driftless Wisconsin, and I captured this video of some eager nestlings the other day.

*Kestrel's grows so fast that when I missed a week of visiting them,
they went from only the head is visible to them standing outside the
nest*

Cool. We have 5 females hatchlings in our box. We saw a head looking out of the box this morning.
