We saw this dark-eyed junco yesterday in our backyard. He was playing in the rain. There are a few different varieties of dark-eyed juncos. This one is a slate-colored dark-eyed junco, which is the only kind of junco found in Wisconsin. Juncos are a kind of American sparrow.
You can here a recording of the dark-eyed junco’s song from the Patuxent Wildlife Research Center by clicking here:
