90. Raeburn on the Great Skua. 



[The Great Skua {Stercorarms catarrhactes) : its present status as a 

 British Bird. By Harold Raeburn Scott. Nat. 1891, p. 18.] 



]VIr. Raeburn gives us very interesting information on an 

 ornithological subject which has recently attracted much 

 public attention, and has actually been honoured with a 

 " leader " in ' The Times ' ■\, namely the present state of the 

 three colonies o*f the Great Skua existing in the British 

 Islands. These breeding-stations are all in the Shetland 

 'group — Foula, Uust, and Northraavin, the last named, origin- 

 ally the largest, being now almost deserted. In 1890 the 

 only pair of young hatched on Northmavin were carried off. 

 Altogether it is estimated that " about 75 pairs are the entire 

 number of Great Skuas at present nesting on British soil."
