him (Orn. Jalirb. 1905, p. 65) as Phyllopneusie trochilus. 

 He notes at the same time that " birds were seen on this 

 date" in Fuerteventura, and even later a few remained." 

 I have examined both skins, which are in theTring Museum, 

 with Dr. Hartert, and there is no doubt that they are 

 examples of the European Chiffchafl' (P. coUijhita collybita). 



The same observer, Herr von Thanner, is responsible for 

 the three following records '. — 

 14 Marcli, 1905. " Many birds passing through Fuerteventura " (Orn, 



Jahrb. 1908, p. 214). 

 13 March, 1912. "A male bird obtained in Fuerteventura" (Orn. 



Jahrb. 1912, p. 22G).

o A 1 -■r^■.r^ -< VButura bctweett these dates" (Orn. Jahrb. 1912,

The above records would certainly only entitle the 

 European ChifFchaff to be considered an Occasional Visitor 

 to the islands. As, however, it has appeared in considerable 

 numbers on each occasion that it has been noted, and 

 taking into account the scarcity of observers (there is no 

 ornithologist in Fuerteventura) and the presence of two 

 resident closely allied subspecies, 1 feel justified in calling 

 it a Bird of Passage which usually escapes detection. 



Range. The Chiffchaff breeds in Europe and winters in 

 southern Europe and northern Africa. There are specimens 

 of P. c. collybita in the Triug Museum from Mazagan in 

 Morocco (Sept., Nov., Dec, and Jan.) ; from Seksawa 

 (April) ; Biskra (Feb.) ; and one bird from Thies, Senegal, 

 obtained on 26 January by Riggenbach.
