Birds of paradise are generally crow-like in general body-form, and, indeed are the brother group to the Corvids (crows & jays). They have stout or long bills and strong feet, with around two-thirds of the species being strongly sexually dimorphic. They live in tropical forests, including rainforest, swamps and moss forest. In most species, the diet consists predominantly of fruit, although riflebirds and sicklebills also favour insects and other arthropods.
