American crows, Northwest crows, and ravens
On my recent trip to Seabeck, WA, at low tide on Seabeck Bay, I spent some time in Meeting for Worship with Attention to Shore Birds. More on that wonder later, with pictures, I hope.
Some of those birds were crows; and I commented on an email list recently about how much more gregarious crows are in the Pacific Northwest of the US than they are in the Mid-Atlantic. Someone asked, Might they have been ravens?
I was pretty sure they weren't -- they didn't look enough different from crows, for one -- but this did prompt me to go do some research, especially at U Mich's Animal Diversity Web. Which, among other things, often has great recordings of bird calls.
Yes, there's a difference between the American crows I grew up with in the East, and the Northwest crows I became friends with in Seattle and visited with there and on the Kitsap Peninsula this trip. And neither of them are ravens.
Here's what I found. Enjoy!
Here's how they sound, which caused me to say, "Yep! That's them!":
