The King of Saxony Bird of Paradise, Pteridophora alberti, is a small, approximately 22cm long, passerine of the Paradisaeidae family. It is the only member in monotypic genus Pteridophora. The adult male is a black and yellow bird of paradise with a dark brown iris, black bill, brownish-grey legs, aqua green mouth, and two remarkably long, scalloped, enamel blue brow plumes that can be erected at the bird's will. So bizarre are its ornamental head plumes that, when the first specimen was brought to Europe, this bird was thought to be a fake. The unadorned female is a greyish brown bird with barred below.
