Ruff-necked Humming-bird

Although it is one of the smaller members in a family of very small birds, this species is notably pugnacious. The male Rufous, glowing like new copper penny, often defends a patch of flowers in a mountain meadow, vigorously chasing away all intruders (including larger birds). The Rufous also nests farther north than any other hummingbird: up to south-central Alaska. Of the various typically western hummingbirds, this is the one that wanders most often to eastern North America, with many now found east of the Mississippi every fall and winter.
