Pomarine jaeger

Description

The pomarine jaeger (Stercorarius pomarinus),pomarine skua,or pomatorhine skua is a seabird in the skua family Stercorariidae.It is a migrant,wintering at sea in the tropical oceans.This species ranges from 46 to 67 cm (18 to 26 in) in length,110 to 138 cm (43 to 54 in) in wingspan and 540–920 g (1.19–2.03 lb) in weight.The upper limit of the length includes the elongated tail streamer of breeding adults,which is about 10 cm (3.9 in) in length.Identification of this jaeger is complicated by its similarities to parasitic jaeger and the existence of three morphs.Pomarine jaegers are larger than common gulls.They are much bulkier,broader-winged and less falcon-like than the parasitic jaeger,but show the same wide range of plumage variation.
