About These Birds
Black-billed Sicklebill
The Black-billed Sicklebill is a large bird of paradise of New Guinea's montane forests, with the male displaying deep brown plumage, a long tail, and an extraordinarily long, strongly curved black bill used to probe for nectar and extract grubs from bark. It inhabits primary mid-montane forests across the main island of New Guinea. It feeds on arthropods, nectar, and fruits.
Raggiana Bird-of-paradise
The raggiana bird-of-paradise is the national bird of Papua New Guinea, featured on the national flag and coat of arms.

Alfred Russel Wallace first described the species in 1873.
