They are doing the exact. same. thing here. In our pines. It's really a bit unnerving.

I don't know enough about crows to know why. I do know they're smart.

This is spooky. I live in Nebraska, and about a month ago I heard them doing the very same thing. Definitely creepy.

Someone else added a link about why they do it - it's all part of roosting.

The Birds messed us all up!

That explains things!

Wow! That was crazy!

The roosting idea makes sense. There's flock of swifts that return every year to a Portland elementary school's chimney. Now that I know what they were doing, not so scary.

very Hitchcockian!

I had not watched The Birds until this year - although I read the short story when I was a teenager. I understand Hitchcock bought the story and kept little of it beyond the title and the basic idea.
