The lightwell my windows open into has had turtle doves nesting for the last two years, and now we've had what appears to be a black-chinned hummingbird move in. They're quite neat to watch. This one has set up in a camilia tree.
I put my camera (Canon PowerShot SX100IS) on a ladder and used the 10X optical zoom to get a decent shot. The picture quality for video is quite decent for 640x480.
The bird leaves and returns with some feather down, presumably building or maintaining the nest. It appears to have a long tongue, as well.
