## Summary

The parasitic jaeger or arctic skua (Stercorarius parasiticus), also known as the parasitic skua or arctic jaeger, is a seabird in the skua family Stercorariidae. It is a migratory species breeding in Northern Fennoscandia, Scotland, Iceland, Greenland, Northern Canada, Alaska, and Siberia and wintering across the southern hemisphere.
