[JAEGER Stercorarius sp.]

Status Vagrant. Three species of Stercorarius spp. have been recorded in New Guinea waters but only Pomarine Jaeger S. pomarinus is considered a ‘common’ migrant in northern New Guinea (Beehler & Pratt 2016) . Two unidentified jaegers were seen between Biak and Yapen on 18 December 1962 and one between Biak, Supiori and Numfor on 29 March 1963, both immatures (King 1979).
