black-backed thornbill Ramphomicron dorsale

Extremely short-billed hummingbird found at high elevations in Colombia’s Santa Marta Mountains. It mainly occurs in remote areas with little access, and is rare and perhaps seasonal in the areas most visited by birders, such as El Dorado Nature Reserve. Male has a black back and green throat; the throat patch is reduced on young birds. Female has spotted underparts and white tail tips. Inhabits humid forest and often clings to flowers while feeding. Visits feeders on rare occasions.
