The Manus friarbird, known locally as the chauka, is represented on the Manus provincial flag. The same is also true of the New Guinea friarbird ("P. b. novaeguineae"). The noisy friarbird was first described by ornithologist John Latham in 1790. These include the orange-footed scrubfowl, the lesser sulpher crested cockatoo, and the helmeted friarbird. Molecular study shows its closest relative to be the silver-crowned friarbird within the genus "Philemon". The Tanimbar friarbird ("Philemon plumigenis") is a species of bird in the family Meliphagidae. The helmeted friarbird ("Philemon buceroides") is a species of bird in the family Meliphagidae. The New Britain friarbird ("Philemon cockerelli") is a species of bird in the family Meliphagidae. Additionally, the single member of the genus "Melitograis" is called the white-streaked friarbird.
