Pomarine Jeager

Stercorarius pomarinus

Pomarine Jaegars are very uncommon spring migrants and uncommon fall migrants to the Pribilof Islands. On a typical year one or two individuals will be detected in late May and June, and between four and several dozen will be seen during early July and late September. Most sightings are of adult birds, replete with their characteristic twisted and spoon shaped central retrices. Pomarines typically fly with deep and robust wingbeats, and their barrel chested look and heavy bill make them look like larger and more powerful birds than their smaller, more gull-like parasitic cousins. If a candidate jaeger passes close to shore look also for the two white flashes in the primary and primary covert shafts of the upperwing, the large flash of white in the upperwing primary shafts, the broad and dark collar around the breast, and the rich golden wash across the nape. Jaegers often pass by at some distance from shore, making their identification very difficult. Distant birds should often be left as Jaeger sp. Good places to watch for flyby Jaegers include Reef Point, Southwest Point, Northeast Point and Marunich.
