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.
Sooty Barbthroat
A medium-sized hummingbird (10-12 cm) found in humid lowland forests of the eastern Amazon basin and the Guianas. Dark sooty-green plumage. Nectarivore of dense forest undergrowth. One of the least known hermit hummingbirds due to its restricted range in remote forests.
