The sword-billed hummingbird (Ensifera ensifera) is a species of hummingbird from South America and the sole member of the genus Ensifera. It is found in the higher elevations (mostly above 2500 meters) in Bolivia, Colombia, Ecuador, Peru and Venezuela.

It is noted as the only species of bird to have a bill longer than the rest of its body. This adaptation is to feed on flowers with long corollas such as Passiflora mixta. The tongue is therefore also unusually long.

Since the sword-billed hummingbird’s beak is very long, it grooms itself with its feet. From base of the bill to the tail tip, this species averages 14 cm (5.5 in) in length, not counting the 10 cm (4 in)+ bill. This hummingbird weighs about 10–15 g (0.35–0.53 oz) and is one of the largest species of hummingbirds. source
