One of the largest hummingbirds in the Amazon, the Gray-breasted Sabrewing is fairly dull in appearance. Both sexes are gray below with a conspicuous white spot behind the eye and broad white tips on the outer tail feathers. They are denizens of humid forests, especially near streams and openings. Gray-breasted Sabrewings prefer to forage on flowers in the lower and middle level of forest and they also visit feeders. They are often seen on open perches along the forest border which they leave to chase other hummingbirds.
