SKUAS AND JAEGERS. 85 



[Note:. The Southern Skua. Megalestris antarcticus, 

 which closely resembles our Northern Skua, and which 

 breeds on Kurguelen Island, is said not to rob Gulls and 

 Terns. Is has hawk-like habits and preys upon other birds, 

 especially the young O f species that nest on the island. 



These hawk-like habits are shared to some extent not 

 only by our Skua, but also by all of our Jaegers, more fre- 

 quently, however, when on their breeding grounds. All 

 members of the group are sometimes scavengers.]
