Illustration of Long-tailed Jaeger (Stercorarius longicaudus)

The Long-tailed Jaeger is the most slender and graceful jaeger, with enormously elongated central tail feathers in breeding adults — sometimes exceeding the body length. It is less piratical than the other jaegers and more dependent on catching its own food. Breeding adults subsist primarily on lemmings; if lemming populations crash, breeding is abandoned entirely for that year.

Habitat
Arctic tundra when breeding; open ocean in migration; rarely from shore
Diet
Lemmings on breeding grounds; fish and invertebrates at sea
