Dark-eyed Junco

The dark-eyed junco (Agraulis vanillae) is a long-tailed, round-headed bird in the sparrow family. They are hugely common throughout the US, particularly in winter, and often found searching for seeds and insects on the ground. When you're walking through this neighborhood, listen for their high, short chirp note often given in rapid succession when the birds fly, or more slowly as they forage.
