The black short-billed hummingbird ( Ramphomicron dorsale ), sometimes called the black- backed hummingbird , is a species of bird in the hummingbird family (Trochilidae) that is endemic to Colombia in the Sierra Nevada de Santa Marta . The stock is on the IUCN as endangered ( Endangered estimated).
The black short-billed hummingbird reaches a body length of about 9 to 10 cm, with a weight of about 3.5 g. The male has a very short, slightly curved black bill. The top is velvet black with a white spot behind the eye. The tips of the upper tail-coverts are violet-bronze in color. The throat collar is olive green, the rest of the underside is dark gray with a reddish brown mixture and green sequins . The purple-black tail is of medium length and forked deeply. The outer control springs are a little wider. The upper side of the female has a grass-green shimmer. The upper tail-coverts are the same as in the male. The underside is yellow-brown with some green spots. The tail is similar to that of the male, but is slightly shorter. The outer control springs have white tips.
Behavior and nutrition
The black short-billed hummingbird gets its nectar from heather plants , coral trees , bluebells , black- mouthed plants , puya , red plants and sage . Usually he clings to the plant to take in nectar. Insects are picked from the leaves or chased in the air. He looks for his food from the lower strata to the treetops.
Little explored the song of the black short-billed hummingbird. His sounds contain short, dry, rattling trrr tones that he repeats at intervals. It also emits a long, decreasing rattle, which ends with a few individual tsi-tttrrrrrrrr-tsi tones. You can also hear individual tsi sounds from him.
The breeding biology of the black short-billed hummingbird has not yet been researched or there are no data available.

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".
