These birds come in two distinct looks—a “light morph” and a “dark morph”

Population 400,000 – 600,000

It is a medium-sized seabird with a much more slender build and a narrower wingspan, giving it the sharp, pointed silhouette of a falcon. What technically separates it from other members of the jaeger family is its tail: instead of the twisted “spoons” of the pomarine or the long, flowing ribbons of the long-tailed jaeger, the prasitic sports two pointed, dagger-like central feathers that stick out just a few inches beyond the rest of the tail.

True to its name, this bird is a master of “kleptoparasitism.” It is a professional harasser of terns, puffins, and gulls. Because it is so lightweight and nimble, it can match every twist and turn of a smaller bird in a high-speed dogfight. It will dive-bomb and snap at its target until the victim gets so stressed that it “regurgitates” or drops the fish it was carrying for its chicks. The jaeger then performs a spectacular mid-air catch, snatching the stolen meal before it can hit the waves. What makes them particularly “humanized” is their tactical intelligence; they often hunt in pairs, with one bird acting as a distraction while the other swoops in to make the “hit.”

When they aren’t pirating on the high seas, they lead a double life as Arctic dwellers. During the summer breeding months, they move to the coastal tundras and moorlands. Unlike their pomarine cousins, who are obsessed with lemmings, the parasitic jaeger is a more versatile eater. They will snatch up insects, berries, and even the eggs or chicks of other birds. They are also incredibly brave—if a fox or a human wanders too close to their ground nest, they won’t just fly away. They will launch a ferocious aerial dive-bombing attack, screaming loudly and swooping inches from the intruder’s head to drive them away from their precious eggs.
