Brown Skua (Catharacta lonnbergi)

Taxonomy

Monotypic
Also known as Subantarctic Skua


 

Identification

A member of the complex large skua group. Separation of this form from Great Skua remains challenging.

Bearhop and colleagues have argued that dark juvenile Great Skuas are more frequent that previously thought, complicating the identification of Brown and South Polar Skuas (Bearhop et al. 1998).
