Male Red-Bellied Woodpecker (This one actually wasn't filtered much--their heads really are that unnaturally vivid color.)
Male and female Eastern Bluebirds
The bluebird from an angle I will probably never paint.
Northern Mockingbird. I got dozens of this guy. It's all the same bird, too. He was a camera hog.
Yellow-Rumped Warbler -- one of a bunch of small, generally interchangeable warblery things that come to the suet.
If anybody wants to use these for reference, go ahead--I'd suggest not copying them exactly, since I'll probably do paintings of them at some point, but feel free to do studies or use them for general ref.
