Schwarzohrkolibri

A medium-sized hummingbird with speckled or spotted underparts — unusual among hummingbirds dominated by plain or iridescent plumages — speckled hummingbirds inhabit cloud forest and forest edges in the Andes from Colombia and Venezuela south to Bolivia at elevations of 900–3,000 meters. The spotted underpart pattern provides remarkable camouflage when the bird perches on lichen-covered bark. They forage on nectar and small arthropods and are important pollinators of Andean epiphytes.
