About the Pomarine Jaeger

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. The pomarine jaeger is most closely related to the larger skuas (species formerly placed in a separate genus Catharacta: great skua, Chilean skua, brown skua, and south polar skua). Together, the pomarine jaeger and the larger skuas are sister to the two smaller skua species, the parasitic jaeger and long-tailed jaeger.

The evolutionary relationships of the pomarine jaeger were formerly controversial. Based on plumage similarity between the pomarine jaeger and the two smaller jaegers (long-tailed jaeger and parasitic jaeger), the three jaegers were formerly placed in a separate genus from the larger skuas (with the jaegers in Stercorarius and the larger skuas in the former genus Catharacta). However, behavioural evidence was recognized early on as suggesting a link between the pomarine jaeger and the larger skuas: for example, both pomarine jaeger and great skuas perform wing-raising displays, a behaviour that is absent in the two smaller jaegers.
