Raggiana Bird-of-paradise

Overview

The Raggiana Bird-of-paradise is one of the most widespread and culturally significant birds-of-paradise, serving as the national bird of Papua New Guinea. Males display elaborate reddish flank plumes at communal display sites, while females remain plain and cryptic.

• Widespread across much of New Guinea's lowland and hill forest
• Male flank plumes are notably red-orange rather than yellow
• Displays occur at traditional group lek sites

Feather Identification

Adult males show a dark brown body, bright yellow crown, and an iridescent green throat patch, similar to related Paradisaea species. The key distinguishing feature is the flank plumes, which are red to deep orange rather than yellow or white.

• Crown: bright yellow
• Throat: iridescent green
• Body: dark brown
• Flank plumes: elongated, red to orange, softer and more filamentous than typical contour feathers
• Tail: dark, unremarkable relative to the plumes

Red-orange flank plumes distinguish this species from the yellow-to-white plumed Greater Bird-of-paradise and the shorter, paler-plumed Lesser Bird-of-paradise.

Plumage Notes

Males take several years to mature into full adult plumage, resembling females during early life stages. Females are plain brown overall, lacking the yellow crown, green throat, or elongated plumes of adult males.

• Adult males: ornate plumage with red-orange flank plumes
• Females and young males: plain brown, cryptic plumage
• Multi-year maturation period before full plumage develops

Habitat & Range

Widespread across lowland and hill rainforest of eastern and southeastern New Guinea, extending into parts of the country's more populated regions.

• Non-migratory resident within forested lowland and hill habitat
• Tolerates some degraded or secondary forest better than more specialized relatives
• Found from near sea level into lower montane forest edges

Behavior & Field Notes

Males display communally at established lek trees, competing to attract visiting females through synchronized plume displays. Diet is largely fruit-based, supplemented with small animal prey.

• Voice: loud, repeated calls, especially vocal during morning display bouts
• Nesting: females build and tend nests without male assistance
• Field notes: the red-orange flank plumes are the clearest way to separate displaying males from closely related Paradisaea species
