The Calliope Hummingbird is another of the many species of hummers you may see while visiting the Santa Rita Mountains south of Tucson. This is one of the tiniest of hummers found in this area, but makes up for size with beautiful plumage. It is the smallest of all hummingbirds in North America.
The Calliope Hummingbird has iridescent green feathers on the upperparts, and is white on the underside. The feathers on the throat are purplish to red streaks on white. Its ability to hover it typical of hummingbirds, and its wing beats are so fast you can hardly see the wings at all.
The Calliope Hummingbird is one you might see in Madera Canyon, but since this species loves the higher elevations, you might just see one nearer to Mt. Wrightson. It has been spotted at elevations over 11,000 feet.
