It’s a peregrine nest, seeming to consist of amorphous lint from our basement dryer. I happened to watch for ~15 minutes when along came the mother bird with food (a rat?).
A chick pops up from the mass. Then two, three and finally four. Yes four baby peregrines. It’s really neat.

Worth a look.
Very interesting.
I was horrified when I first clicked on the link, thinking that the birds must have been born with no bones since they looked so flat.
Then one of them stood up, and the horror abated a little.
Wow, that’s great! I had to zoom in before I could make out the little ones. Thanks.
Thank you for posting that link. I watched them fidget for a while, but they’ve finally settled in for a nap. I hope to get to see mama come back in with a snack.
What a cool link! I got to see one of the chicks pop it’s head up out of the “amorphous lint” (excellent description, E = mc[SUP]2[/SUP]). No mom, though. Maybe later.

Can you post any stills of the chicks or mom? I only got to see the nest. 
I’ll check back later. Thanks for the cool link.
:o Nevermind, I found the gallery. Sorry.
Beautiful plumage!

I was hoping you’d love seeing the birds, so it was so nice to see that you did.
I’ll give that other cam a try. Thanks for the tip, OtakuLoki.
Here’s another birdcam. Their first chick hatched yesterday! I’m so excited.

I checked your link, E = mc2, and saw the mother bird feeding her young’uns. So cute!
They are eating now.
