Green-throated mango hummingbird: This species loves mangrove and swamp forests, and can be found along a narrow strip of the Atlantic Coast along the north and south of the Amazon river outlet. Though not much is known about this species, it is known that the population occurring in Trinidad is now rare due to the loss of its preferred swamp and mangrove habitat.

Sword-billed hummingbird is a species of hummingbird from South America. 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. The tongue is therefore also unusually long. Since the Sword-billed Hummingbird's beak is so long, it grooms itself with its feet. From base of the bill to the tail tip this species is approximately  14cm long. Photo: Derek Kverno
