Arctic Skua / Stercorarius parasiticus

Not many people have heard of an Arctic skua, but if you were wondering what they look like...

Arctic skuas, also called parasitic Jaeger's, have a well-earned reputation as avian pirates, stealing much of their food from other birds.  These aggressive sea birds are sometimes referred to as avian pirates. The name is well earned. Skuas steal much of their food from terns, puffins, and other birds that are carrying fish or other prizes back to their nests and young, they strike other birds while airborne.

These birds are devious Carnivores.

Did you know?
The word “skua” comes from the Old Norse term for seagull.

They are similar to the size of a duck.

Arctic skuas live most of their lives at sea, and come ashore only to breed in the Arctic summer. "Kleptoparasitism" is the term for stealing food from other species, while "jaeger" is derived from the German  word "hunter."

These birds are not endangered.
