The Raggiana bird of paradise (Paradisaea raggiana) Papua New Guinea's national bird, is featured on the country's flag and stamps. It is named after Marquis Francesco Raggi, an Italian naturalist and collector. The name was given at the request of Count Luigi Maria D'Albertis, who collected the bird and sent specimens to be named after Raggi. The "Paradisaea" part of the name is from the Latin "paradise", reflecting the bird's stunning appearance and the historical perception of these birds as being from a paradise-like origin. The Raggiana bird of paradise is known for its vibrant plumage and elaborate courtship displays. Males have striking orange-red flank plumes and iridescent green throats, which they fan out during lek displays to attract females. They are also important seed dispersers for certain trees like mahogany and nutmeg. The female Raggiana bird of paradise has chocolate brown facial plumage, a yellow crown and nape, and paler underparts. While not as visually striking as the males, she plays a crucial role in the species' survival. She builds the nest, incubates the eggs, and cares for the young alone, relying on her duller plumage for camouflage.
