pomarine jaeger

The pomarine jaeger (Stercorarius pomarius) is a species of seabird belonging to the genus Stercorarius. It is larger and darker than the parasitic jaeger, with somewhat elongated but obtuse middle tail feathers. Jaegers, also known as skuas in Britain, resemble dark gulls and have a forward-set black cap and projecting central tail feathers. They nest in the Arctic tundra and then migrate to sea, with some traveling as far as Australia and New Zealand. While at sea, they catch fish independently. However, when nesting, they harass other seabirds like terns and kittiwakes to force them to disgorge food, destroy the eggs and young of other seabirds, and capture land birds and rodents. The pomarine jaeger is the largest species of jaeger, measuring 50 cm (20 inches) in length.12
