Here's a 2008 hummingbird migration map for anyone who likes to keep track of such things.
Thanks for the great hummingbird link. I've bookmarked it and will keep an eye on it. I'm up in the frozen Minnesota tundra so it will be awhile until the little guys return (25 degrees this morning with some snow on the ground).
We had eight hummingbirds spend the summer with us last year. It was so much fun watching their antics. If I wore a brightly colored shirt with flowers they would occasionally land on me. I can't wait until they return.
