What is "astrapia"

The astrapias are a genus, Astrapia, of birds-of-paradise. The genus contains five species.

They are endemic to New Guinea. The males have highly iridescent plumage and remarkably long tails. Females are duller and have shorter tails.

Barnes' astrapia is a hybrid produced by the interbreeding of Princess Stephanie's astrapia and the ribbon-tailed astrapia.
