description Sword-billed hummingbird Overview
The sword-billed hummingbird is a unique South American hummingbird inhabiting the Andean slopes of eastern Peru and northern Bolivia. It’s notable for possessing an extraordinarily long, curved bill—the longest among all birds—which it uses to access nectar deep within tubular flowers. This specialized adaptation makes it essential for studying Ensifera evolution and attracts ornithologists, researchers, and bird enthusiasts fascinated by extreme adaptations in avian anatomy.
help Sword-billed hummingbird FAQ
How long is the sword-billed hummingbird's beak?
The sword-billed hummingbird's bill can measure up to about 10 centimeters (roughly 4 inches) long, exceeding the length of its body excluding the tail. This makes it the only bird species in the world whose bill is longer than the rest of its body.
What flowers does the sword-billed hummingbird feed on?
The sword-billed hummingbird has co-evolved with deep-tubed flowers, particularly certain species of Passiflora (passion flowers) and Datura, whose long corollas match the bird's extraordinary bill length. It is one of the few pollinators capable of reaching nectar at the base of these flowers.
Where does the sword-billed hummingbird live?
The species is found along the Andes mountain range from Venezuela through Colombia, Ecuador, and Peru, extending south into Bolivia. It typically inhabits humid montane forest and forest edges at elevations between approximately 1,700 and 3,500 meters.
How does the sword-billed hummingbird perch with such a long bill?
The bird must tilt its head sharply upward when perched so that its extremely long bill does not hit the branch beneath it. This distinctive upward-angled posture is one of the easiest field marks for identifying the species in its Andean habitat.
