Here's good one to bookmark and browse at your leisure. It's the site for the annual
Veolia Environnement Wildlife Photographer of the Year, done, I think, with BBC Wildlife magazine and the Natural History Museum.
One of the bird images is a terrific shot of a juv Bald Eagle about to catch a Red-Winged Blackbird. As my wee nephew would say (he is still working on his verb tenses): "How he do's that?!"
