Thank you for your kind words!

It depends on the region you are in, but American Crows are very widespread. I recently read an article that the Northwestern Crow has basically been absorbed into the American Crow species because of so much interbreeding. I think most of the time it's a safe bet to call them American crows.
How lucky to have a nest in your yard! If we were neighbors I would probably be coveting your rooftops for photo ops, lol.
