The lesser bird-of-paradise (Paradisaea minor) is a bird-of-paradise in the genus Paradisaea.
The lesser bird-of-paradise is medium-sized, up to 32 cm-long, maroon-brown with a yellow crown and brownish-yellow upper back. The male has a dark emerald-green throat, a pair of long tail-wires and is adorned with ornamental flank plumes which are deep yellow at their base and fade outwards into white. The female is a maroon bird with a dark-brown head and whitish underparts. Further study is required, but it seems likely that birds-of-paradise also possess toxins in their skins, derived from their insect prey.
It resembles the larger greater bird-of-paradise, but the male of that species has a dark chest, whereas the female is entirely brown (no whitish underparts).
