Parasitic Jaeger
Also known as the Arctic Skua, they aggressively protect their nests - be careful!
What you need to know about the Parasitic Jaeger
Our Expert Says… "As well as dive-bombing, Parasitic Jaegers have another fascinating defensive behavior. One will sometimes pretend to be injured on the ground, trying to lure you away from the nest by feigning the fact that they might be an easy meal and distracting you from the nest."
The parasitic jaeger is sometimes also known as the Arctic skua. Smaller than many other skua species, the parasitic jaeger grows to about 45cm (18”) long with a 1.15m (45”) wingspan. It can be tricky to identify this skua as it occurs in three different colors (known as “morphs”) ranging from brown with mainly-white underparts to all dark-brown. They all have a white flash on the wing.
A migratory species, parasitic jaegers overwinter in the tropics and return to the northern arctic to nest on dry tundra, hills, and remote islands. However, there is also a significant population that breeds in the north of the UK, including the Shetland and Orkney Islands and the Outer Hebrides. They are aggressively protective of their nests and will attack any predators such as foxes that approach by dive-bombing them and pecking at the head. They will also take on humans, so be careful in the nesting season!
The Arctic skua’s name of parasitic jaeger is given because of its main feeding habits. Jaeger is from the German word for “hunter”, and it’s parasitic because it steals food from other bird species, usually gulls and terns.
Although populations are generally stable, the population of parasitic jaegers in Iceland has suffered a population crash since the early years of the 21st century and they are now listed as “Endangered” here.
