great skua การใช้

Brei餫merkursandur is an important breeding ground for birds, for example Arctic tern and great skua.
Predation by the great skua ( " Catharacta skua " ) is also reduced by several birds arriving simultaneously.
These characteristics are not shared by the larger species, all native to the Southern Hemisphere except for the great skua.
DNA-DNA hybridization results have however sometimes led to misleading conclusions about species, as with the pomarine skua great skua.
For great skuas and other scavenging birds of the North Sea, there's no longer such a thing as a free lunch.
