Calliope hummingbird spotted at Carson City feeder
A Calliope hummingbird eating at a feeder in Carson City. This is the smallest bird in North America, measuring about 3 inches long and weighing about one-tenth of an ounce.
Despite its tiny size, it is able to survive cold summer nights at high elevations in the northern Rockies, and some migrate every year from Canada all the way to southern Mexico. In migration it may be overlooked, often feeding at low flowers and avoiding the aggression of larger hummingbirds.
