This large hummingbird is classified as “near threatened” due to loss of habitat from land conversion by humans. It inhabits the understory of humid montane forests, elfin forests, and second growth woodlands. In Peru, Napo Sabrewings are mostly found on outlying mountain ridges. They search for food at low to medium levels of the forest where they feed on both nectar and insects. These dark hummers have a sparkling green crown and white spot behind the eye. Males have an iridescent throat and breast while females are mostly dark gray below.
