September 27, 2014 - Parasitic Jaeger, Arctic Jaeger, Arctic Skua, or Parasitic Skua (Stercorarius parasiticus)
Requested by: karrikut
These birds have an extremely large range and can be found in parts of North and South America, Europe, Asia, Africa, and Australia. They breed mostly in Arctic Tundra and spend much of their winters at sea, often within a few miles of land. There are light and dark morphs of Parasitic Jaegers, as well as birds with intermediate plumage. Their name refers to their habit of stealing food from other birds, a behavior known as kleptoparasitism. They harass terns, gulls, and auks until they drop their catch, often catching the stolen fish in the air. Small birds, eggs, and rodents make up the rest of their diet.
