The collared sunbird (Hedydipna collaris) is a bird species of the family Nectariniidae. The sunbirds are a group of very small Old World passerine birds which feed largely on nectar, although they will also take insects, especially when feeding young. The collared sunbird is in fact mainly insectivorous. Sunbird flight is fast and direct on their short wings. Most species can take nectar by hovering like a hummingbird, but usually perch to feed most of the time. This species inhabits forests near water.
