Where to see them
Did you know…?
It is a specialist kleptoparasite: it chases terns and gulls with extraordinary agility, matching every turn of its victim until it drops its catch, and takes it in mid-air before it hits the water.
From Parasitic Jaeger
Two colour morphs, pale and dark, occur in the same population, and their proportions vary with latitude: dark birds predominate in the south and pale ones in the high Arctic.
From Parasitic Jaeger
In the Arctic it defends its nest by diving at foxes, reindeer and people, striking the intruder's head with its feet.
From Parasitic Jaeger
It is a professional pirate: it chases a gannet far larger than itself, grabs it by the wing or the tail and harries it until it regurgitates its fish, which the skua then catches in mid-air.
From Great Skua
It dive-bombs anyone who approaches its nest, human beings included, and in Iceland and Scotland walkers are advised to hold a stick above their head during the breeding season.
From Great Skua
It is one of the very few birds observed at the geographic South Pole, and it also migrates in the austral winter as far as the waters of Greenland and Alaska: few species in the world cover such an enormous span of latitude.
From South Polar Skua
Both chicks from its two eggs rarely survive: the elder usually attacks the younger systematically until it is gone, an obligate siblicide common in several seabirds.
