Parasitic jaeger can reach 16 to 19 inches in length and 0.66 to 1.43 pounds of weight. Females are slightly larger than males.
Parasitic jaegers can be "light" or "dark" colored. "Pale" parasitic jaegers have grayish-brown body, whitish belly, black cap on top of the head and yellowish-white sides of the neck and head. "Dark" parasitic jaegers are covered with brown plumage.

Males perform various acrobatics in the air to attract females. Formed couples can last one or more seasons. Parasitic jaegers produce cat-like calls during the breeding season.
Parasitic jaegers can nest solitary (in tundra) or in loose colonies (on the islands). Both males and females aggressively defend their nest. They produce shrieking calls and use bills and feet to repel intruders from the nesting area.
Female lays 2 to 4 olive-brown eggs into the shallow depression in the ground. Both parents participate in the incubation of eggs, which lasts 26 to 27 days.
Chicks can leave the nest 24 to 48 hours after hatching. Both parents collect food for their chicks until they become able to fend for themselves. Young parasitic jaegers learn to fly at the age of 26 to 30 days. They fly toward the wintering grounds at the beginning of the autumn and often stay there until the age of 2 years.
Parasitic jaegers reach sexual maturity at the age of 3 to 4 years.
Parasitic jaeger can survive up to 32 years in the wild.
