Many people complain to me that they find winter birding dull because there are no pretty birds around.
True, the winter residents at most feeders, pine siskins, chickadees, nuthatches, hairy and down woodpeckers, house sparrows, house finches, and the various forms of the dark-eyed junco are mostly gray, brown, and black-and-white birds. Not very exciting or colorful, but they are still interesting.
