Black-billed Magpie
Magpies are not usually seen this far north. However, this last fall in late September (2010), this magpie kept coming to visit our dogs for about a week. I was surprised when I still recognized his call since I hadn't seen magpies in so long. (I used to live where I saw them all the time.) One morning, I even witnessed this magpie and a raven flying around together, seeming to be at play.
