Buffy Hummingbird

The male and female buffy hummingbird are similar in appearance but the female tends to be less brightly coloured, and there is considerable variation in shade between individuals. The back and upper parts of the bird are a dull green, the underparts pale cinnamon-buff and the belly and undertail coverts white. The tail is dull green with a transverse grey bar and a rounded end. There is a white spot behind the eye and the beak is slender and straight. The upper mandible is black and the lower one pale with a black tip. The bird ranges from 8.5 to 9 cm (3.3 to 3.5 in) in length.

The buffy hummingbird is found in Colombia, French Guiana, and Venezuela. Its natural habitats are desert shrubland, thorny shrubs in arid areas and mangrove areas at elevations of up to 500 metres (1,600 ft). It forages at medium heights and near the ground. It tends to feed near the canopy of the forests that it inhabits.

Hummingbirds are specialist feeders on nectar and the buffy hummingbird consumes the nectar of such plants as Agave and Hibiscus and various species of cacti. The hummingbird will protect the flower patches that it feeds from. This hummingbird is unusual in that it also consumes the exposed flesh and the juice of the fruits of cacti in the genus Armatocereus. This hummingbird also plays an important role in the pollination of flowers of Melocactus, carrying the pollen on its plumage as it moves from flower to flower sipping nectar. In addition to plant matter, the bird consumes insects, which it catches in flight.
