The Bird of Wuhan

The most common type of bird on campus is sky blue and black, and quite large; I see them all the time.  I don't remember ever seeing this kind of bird before, but they're really pretty.  I've been wanting to get a picture of one of them ever since I got here, but it seemed whenever I saw one up close I never had my camera ready.  Finally, this morning, a few came along and perched for a moment in the trees in front of my building.  I grabbed my camera and tried to not to scare them off by opening the window.  I got this shot, not that great, but at least you can see it, before they flew off.

Edit: One of the other American teachers here in Wuhan already found out: it's an Azure-winged Magpie.
