The horned sungem (Heliactin bilophus) is a species of hummingbird native to Brazil, Bolivia and Suriname. It prefers open habitats such as savanna, grassland and garden, and expanded its range into southern Amazonas and Espírito Santo, probably due to deforestation. It is a small hummingbird with a long tail and a short, black bill. The sexes differ in appearance, with males having two shiny red, golden, and green feather "horns" above the eyes, a shiny blue head crest and a black throat with a pointed "beard". The female is plainer, with a brown or yellow–buff throat. It is a nomadic species, responding to the seasonal flowering of its food plants. If a flower's shape is unsuited to the bird's short bill, it may rob nectar through a hole at its base. It also eats small insects. Only the female builds the small cup nest, incubates the two white eggs, and rears the chicks. The species is currently classified as least concern, and its population is thought to be increasing.
