The pomarine jaeger is a robust predatory seabird whose breeding adults have twisted spoon-shaped central tail feathers. Plumage ranges from pale to dark. It nests on Arctic tundra, feeding heavily on lemmings, then spends winter over warmer oceans. At sea it pursues gulls and terns to steal fish and also captures fish, seabirds and other prey directly (Wikipedia, general species account). It is Nationally Least Concern (Thailand Red Data 2025).
