 tliey can no longer be considered regular winter visitors. 



Cabrera records tlie Kittiwake in his list (Catalogo, p. 66) 

 as an accidental migrant. It was seen off the island of 

 Palma by Koenig (J. f. O. 1890, p. ^J87). 



In the eastern group I saw a stuft'ed example in the 

 Gonzalez collection at Arrecife, without any data, except 

 that it had been obtained locally (Ibis, 1914^ p. 63). 



Looking through Mr. P. K. Lowe's MS. note-books which, 

 he has been good enough to lend me, I see that he noted 

 Kittiwakes when sixty miles north of Las Palmas, within

 of the Atlantic.

The Common Tern is a Summer Visitor to the islands. 



It used to breed in large colonies in Gran Canaria and in 

 Fuerteventura, but of late years has, I fear, practically 

 ceased to do so. It may still nest on some of the isolated 

 rocks off Tenerife, on the top of which, according to Meade- 

 Waldo, it used in 1891 to lay its eggs (Ibis, 1893, p. 206). 

 Cabrera had both skins and eggs in his collection, and 

 considered it to be a resident (Catalogo, p. Q7). 



Sterna hirundo is first mentioned from the islands by 

 Ledru, who found it in Tenerife in 1810 (Voyage aux isles de 

 Teneriffe etc.). Next it is referred to by Webb and 

 Berthelot in 1841, who give as its habitat "'the islands 

 which are nearest to Africa," i. e. the eastern group. They
