[edit] Etymology
The genus and species name ensifera ("sword-wielder") is derived from Latin ensis (sword) and ferre (to carry), and refers to this hummingbird's remarkable beak length.
[edit] Description
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.[1] From base of the bill to the tail tip, this species is 14 cm (5.5 in) long, not counting the 8 cm+ bill. This hummingbird weighs about 12 grams and is one of the largest species of hummingbirds.
