Learning to photograph birds

We have a new camera, a Canon T1i and are learning to photograph birds.  We use a 55x200 zoom lens for now (we figure we'll learn more about the camera before we get a bigger lens).

Here's a link to our bird photographs.

We're also learning about bird identification, having "graduated" from backyard birding in the valley, so feel free to correct any mis-identified birds.  Any tips about bird photography also welcome - post them here!
