About These Birds
Sword-billed Hummingbird
A remarkable hummingbird (14-15 cm body) with a bill as long as its body (8-10 cm), the longest bill relative to body size of any bird. Found in Andean cloud forests from Venezuela to Bolivia at 1,700-3,500 m. The extraordinarily long bill evolved to feed on deep tubular Passiflora flowers.
Oasis Hummingbird
A small hummingbird (12-13 cm including long tail) found in the arid coastal deserts of Peru and northern Chile. Dull plumage with a long, forked tail. Nectarivore specializing in desert flowers and columnar cacti. One of the few hummingbirds adapted to hyper-arid environments.
