Which Oceanian country's flag features a golden bird of paradise?

Which Oceanian country's flag features a golden bird of paradise? Papua New Guinea. Its flag shows a stylized Raggiana bird-of-paradise in golden yellow on the red upper triangle, while the black lower triangle carries the Southern Cross constellation in white.

The flag was designed by 15-year-old Susan Karike Huhume and adopted in 1971, shortly before Papua New Guinea became independent from Australia in 1975. Its red, black, and yellow palette draws on traditional colors used by many communities across the country.

The bird-of-paradise is strongly associated with Papua New Guinea's cultural identity and appears elsewhere in the country's national symbols. Its upward, soaring pose represents the nation's emergence. The Southern Cross connects Papua New Guinea with other southern-hemisphere countries, including Australia and New Zealand.

A common mix-up is to remember only the bird and overlook the flag's diagonal division. The emblem is specifically a Raggiana bird-of-paradise, a species native to New Guinea, rather than a generic golden bird.
