Arfak astrapia

The Arfak astrapia (Astrapia nigra) is a species of astrapia, a group of birds found in the birds-of-paradise family Paradiseidae.

The Arfak astrapia is the third largest of its genus, being approximately 76 cm (30 in) long, including the tail. The male has a black head with a bluish-purple sheen, or iridescence, an elongated jet-black nape crests extending up along the sides of the up to the eyes on each side, a shiny, metallic greenish-yellow cape from the mantle up to the nape, very black, dense and elongated upper breast feathers, and an almost exaggeratedly long tail almost two times the length of its body. The female is less appealing, being dark brown over most of its body and a blackish head, and sporting much shorter tail feathers. The female is also exceptionally shorter than the male.

Levaillant of France described this bird as L'Incomparable or Incomparable bird-of-paradise.
