So, first I got out a pocket bird book to see the proportions of beak, head, body, wings, feathers, etc., and traced its outline.
After that, I tried to draw one freehand. It was starting to look more like a bluebird...that had been dining on biscuits and gravy, apparently. More practice needed!
So, I googled some bluebird images and printed them, and attempted to draw them. The first one is a copy of the bird book illustration. I colored all the drawings with dry watercolor pencils while watching college basketball on TV. That was much more satisfying than watching my team blow a big lead and lose.
