About These Birds
Coppery Thorntail
A tiny hummingbird (7-8 cm) known from very few specimens collected in Bolivia. Coppery plumage. Almost nothing known about its ecology or current status. One of the most mysterious hummingbirds; possibly rare, possibly overlooked. Further fieldwork needed.
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.
