In nature, it is not always "Peace in the Valley." It's hard to know why these Song Sparrows (Melospiza melodia) appear to be quarreling. They are known to be territorial during the breeding season, but that's over now. I believe they are first season juveniles, but that's a guess. I am used to seeing more gray striping around the eyes. Over the last two months, I have been seeing a lot of juveniles at this BirdCam station.
