What kind of bird is this? I think it might be a wood-pecker of some sort... it likes to sit in my gutters and make a terrible racket... perhaps a gutter-pecker?
After taking this picture, the bird flew off to another house... a bit later, I could hear the same loud racket of the bird 'drilling' in someone else's gutter.
A full-sized image can be found here. Warning though, the file is huge ... about 3.9 megs, 3872 x 2592.
