This one's on a feeder - not nearly as good as a tree, for a wild bird. But the feather detail (in spite of noise) tells me what I need to do is get closer with the long zoom for the tree shots, and try to get away from direct sun on the bird. Those two things in combination aren't easy, since there's a much higher incidence of blur with bird movement, low light, and long zoom. So Geoff I can really appreciate that you managed to get any good ones at all, since I suppose most of those National Geographic type shots are from tripods, and the wait times are pretty long.
