Distribution / Range
Bumblebee Hummingbirds are found in the montane forests of Mexico north to the Isthmus of Tehuantepec. Small numbers migrate to southern Arizona in the summer to breed.
The Bumblebee Hummingbird is the second-smallest bird known to be in existence - second only to the Bee Hummingbird.
It averages 2.75 inches or 7 cm in length and weighing, on average, 0.1 oz or 3 grams. They are comparable in size to bumble bees and are lighter than a Canadian or U.S. penny.
The upper plumage and sides are mostly green. The plumage below is whitish. The rounded tail is green with a rufous base.
The male can be identified by the violet-red gorget (throat patch).
