Range.—Northern hemisphere, breeding north of the Arctic Circle; winter from Mass. southward.
PARASITIC JAEGER
37. Stercorarius parasiticus. 17 in.
Two phases of color, both similar to those of the last, but the central pair of tail feathers are pointed and project about 4 in. beyond the others; bill 1.4 in. long, with the nostril nearest the end. All jaegers have grayish blue legs with black feet, and brown eyes. They are called “Jiddy hawks” by fishermen, who often feed them fish liver. Their flight is like that of a hawk. The nesting habits and range are the same as the next.
LONG-TAILED JAEGER
38. Stercorarius longicaudus. 21 in.
Like the last species, but with the pointed central tail feathers projecting 8 or 10 in. and with a shorter bill (1.15 in.) and the nostril about midway of its length. It is less often found in the dark phase.
Notes.—Shrill wailing whistles.
Nest.—Nest and eggs like those of the [Pomarine Jaeger].
