Field SparrowSpizella pusilla
The plaintive whistled song of the Field Sparrow often can be heard in brushy pastures, even on hot summer days when most birds are silent. Despite the name, this is not one of the sparrows inhabiting open fields of grass; it prefers brushy places, overgrown meadows with many bushes. It looks distinctively small and long-tailed, and its plain face gives it an innocent expression to match the sweetness of its song. In winter, Field Sparrows gather in small flocks.
