Marvelous Spatuletail Photograph by Luis A. Mazariegos Intended to turn female heads, this male's garish tail feathers brag that his biological bank account is full and able to foot the cost of such flashy features.

Scientists estimate that 10 percent of hummingbird species are endangered. See this rare bird in our video presentation.
