according to Hartert, to the Niger on the \vest. It is 

 doubtless sonic of these Hausaland birds that touch at the 

 Canaries in early spring on their way to their breeding 

 (juarters in Europe. 



Specimens in the British Museum from West Africa were 

 obtained on the Gambia river (December) ^ Dakar (October), 

 and in the north from Morocco (Januaiy). There are 

 numerous examples collected in every month from November 

 to March from northern and eastern Africa as far south as 

 British East Africa. 



Motacilla flava. Blue-headed Wagtail.

 Type locality : Sweden.] 



A Rare Visitor. 



This species is intentionally named binomially. Until 

 specimens are collected it is impossible to be certain to 

 which forui these migrants belong. Probably they will 

 prove to be the typical form. 



Tschusi (Orn. Jahrb. 1903, p. 176) records a bird as 

 Budytes flavus as having been shot on 1 May [in Tenerife], 

 reported to him by von Thanncr in a letter dated 30 June 

 [1903]. 



Polatzek (Orn. Jahrb. 1909, p. 12(j) remarks that he saw 

 a few solitary examples of '^Budytes flavus" (Linn.) in 

 Fuerteventura '^' and Lanzarote *. 



Messrs. Webb & Bcrtliclot in their Ijook (Orn. Canarienne) 

 and Hollo in his first paper (J. f. O. 185 J, p. 455) mistook 

 the Canarian Grey Wagtail {M. cinerea canariensis) for this 

 species. Bolle subsequently correctiMl his mistake (J. f. O. 

 1857, p. 286). 



Polatzek has not fallen into this error, however, and knew 

 the Canarian Wagtail intimately. We have no reason, 

 therefore, to doubt his record {supra). 



* The resident Cautirian Wagtail is not fouud on either of these 

 islands during any part of the year.
