Since people keep asking for photos, here's some of the results of a coupla days last week spent with a tripod focused on the suet feeder. Mostly I got bluebirds and a mockingbird, but I'll try again this week. The photos have been filtered a bit since the lighting washed things out, so they may be a little more contrasted than real life--I'm a photographer purely for reference photos and there is very little artistry involved in what I do. (Also, feel free to correct any species identifications--it's always possible I'm wrong!)

Enough caveats!

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.
