These, the most numerous jaegers off Oregon, are slightly smaller than Herring gulls. Gull-like and graceful, these piratical birds steal food from smaller seabirds. They come in a bewildering array of light and dark individuals, confounded by age and sexual differences.
The Pomarine jaeger is an uncommon spring and fairly common fall transient offshore two to 50 miles, following shearwaters. Sightings have been centered near the continental shelf edge. They are occasionally observed from shore in fall.
