Brown-headed Cowbird

Description:

Smallish blackbirds, with a shorter tail and thicker head than most other blackbirds. The bill has a distinctive shape: it’s much shorter and thicker-based than other blackbirds', almost finch-like at first glance. In flight, look for the shorter tail.

Habitat:

Grass fields next to a lake.

Notes:

Banff National Park, Alberta, Canada.
