I'm intrigued by crow behaviour. We have a family of crows that visit us everyday. I believe them to be a couple and one (sometimes, two) offspring. They have become recognizable to us both by their appearance and behaviour. One of them, the one I believe to be the patriach, will linger on my deck railing long enough for me to take a few pictures now. He's happy to consume his treats while I watch, all the while he is also keeping a watchful eye on me!
