Dark-eyed Junco, a member of the sparrow family.
Male Dark-eyed Juncos sing an even, musical trill of 7-23 notes that lasts up to 2 seconds. It’s similar to the songs of both the Chipping Sparrow and the Pine Warbler, and is loud enough to be heard from several hundred feet away. Both sexes sing a much quieter song as well, a series of whistles, trills, and warbles that may sound like an American Goldfinch. This song typically doesn’t carry any farther than about 40 feet.
CALLS
Juncos have a high, short chip note that they often give in rapid succession when they fly and more slowly as they forage; the note may encourage other juncos to follow. A sharp but musical kew seems to indicate aggression and encourages two birds to move apart; it’s usually given by the dominant bird. You may also hear juncos give a high, fast twittering call of 6–19 notes during altercations or as birds flush.
