Etymology and history of research

The first description of the black-footed hummingbirds carried out in 1880 by Osbert Salvin and Godman Frederick DuCane under the scientific name Ramphomicron dorsal . The type specimen was collected by Frederic AA Simons in Sierra Nevada de Santa Marta. Charles Lucien Jules Laurent Bonaparte introduced the genus Ramphomicron as early as 1850 . Ramphomicron is derived from the Greek words »rhámphos ράμφος « for »beak« and »mikron μικρὸν « for »small«. The species name "dorsale" is derived from the Latin "dorsualis, dorsum" for " dorsal , back".
