American Tree Sparrows are small, round-headed birds that often fluff out their feathers, making their plump bodies look even chubbier. Look for small flocks of American Tree Sparrows in winter in weedy fields with hedgerows or shrubs, along forest edges, or near marshes. They readily visit backyards, especially if there's a seed feeder.
This is a fairly small heron with a slight body, slender neck, and fairly long legs. Look for Little Blue Herons on quiet waters ranging from tidal flats to streams, swamps, and flooded fields.
Downy Woodpecker is a familiar sight at backyard feeders and in parks and woodlots. The black upperparts are checked with white on the wings, the head is boldly striped, and the back has a broad white stripe down the center. Males have a small red patch on the back of the head.
