The Crested satinbird, antenna satinbird or crested cnemophilus (Cnemophilus macgregorii), formerly known as the (sickle) crested bird-of-paradise, is a species of satinbird in the Cnemophilidae family. It was formerly placed in the bird-of-paradise family Paradisaeidae until genetic work proved it was unrelated to those birds. It is found in Indonesia and Papua New Guinea. There are two subspecies, nominate macgregorii of southeast Papua New Guinea northwestward to at least the Ekuti Divide, east of the Watut/Tauri Gap and sanguineus of central and eastern Highlands in Papua New Guinea.
