Pomarine Jaeger

General description.

A specie of gull, the "Pomarine Jaeger" is large and stocky and, like the "Parasitic Jaeger", the adults are brown above and light, dusky colored below, with an incomplete gray-brown band across the breast. These jaegers pursue smaller gulls and terns, forcing them to disgorge their dinners, which they snatch up in midair. Possibly seen from land at times, it is more often viewed far offshore.

Breeding habits.

These birds breed on swampy tundra, and during breeding season in Alaska and northern Canada, the Pomarine Jaeger relies on lemmings and small arctic rodents for food. In years when the lemming population is small, jaeger breeding often fails.

Calls or song.

His main call is a harsh, "yowk, yowk, yowk". When uttered by an excited bird, the call generates into sharp screams. While at sea, feeding birds vocalize "which-yew, which-yew, followed by a repeated "week, week, week".

Population and distribution.

Because the "Pomarine Jaeger" is a powerful predator, that feeds on a variety of sources, such as scraps from ships and stolen bounty from other birds, his numbers are not in danger. After breeding, this gull is strictly 'sea-faring' and winters as far north as California and North Carolina.

Nesting habits.

The female "Pomarine Jaeger" lays two olive-brown eggs with darker brown spots in a grass-lined depression on the ground.
