A bird of the Arctic
tundra and open ocean, seen only rarely inland and very rarely in South Dakota.
Adult birds are readily identifiable by the two blunt central tail feathers that
extend well past the rest of the tail. Pomarine Jaegers are
predatory birds, feeding heavily on lemming populations in their northern
haunts, while feeding primarily on fish during the non-breeding season on
the open ocean.
Habitat: Spends summer breeding season on Arctic tundra.
Spends winters over open ocean, usually staying off-shore, and very rarely found
inland.
Diet: Feeds very heavily on
lemmings on its breeding grounds. Breeding success often is dependent on
lemming populations. At sea, primarily eats fish. Will also eat
birds, eggs, insects, carrion, and refuse.
Behavior: On the summer breeding grounds, feeds by
flying slowly and hovering over the landscape, swooping down to capture prey
when spotted. At sea, feeds by dipping down to the ocean's surface
while in flight. They are also agile and strong fliers, capable of
catching small birds in flight.
Breeding: Non-breeder in South Dakota
Song: Generally silent except on Arctic breeding
grounds.
Migration: Summers in the high Arctic. Winters off U.S. coasts as well as elsewhere in the
world. The Pomarine Jaeger is very rare inland, but could be seen in
nearly any season.
Conservation Status: Populations appear to be
stable overall. However, large local population fluxes often occur in
conjunction with availability of primary summer prey species, the lemming.
