contour feathers in spring, but I do not think that the 

 quills are shed then. Capt. Jenkinson informs me that in 

 March 1908 he saw an almost pure white example near 

 Mazghouna in the Giza Province. 



58. MOTACILLA CITREOLA Pall. 



I include this Wagtail among the birds of Giza on the 

 strength of a single immature example shot by Capt. J. W. H. 

 Seppings, not far from the Pyramids, on September 18th, 

 1907, and now in my collection. I have matched this 

 example with specimens in the British Museum. It was 

 doubtless a straggler, as the winter-quarters of the species 

 are much further to the eastward. It is not unlikely, 

 however, that wanderers should occasionally reach Egypt, 

 as specimens have been obtained as far west as Heligoland 

 and in Italy.

The Blue-headed Wagtail is a common visitor during the 

 autumn and spring migrations. I have several specimens 

 shot in September at (riza. 



[60. Motacilla ilava borealis. 



Though Capt. Shelley does not mention this form as 

 occurring in Egypt, and though I have up to the present 

 time obtained, no examples here, I include it amongst the 

 hirds of Giza, as there can be no doubt of its occurrence 

 on migration. Hartert (Vog. d. pal. Fauna, Heft iii. 

 p. 292) mentions it as occurring in Egypt, and I have a skin 

 of an adult male procured by Mr. A. L. Butler in Khartoum 

 in autumn. Up to the present time I have had little oppor- 

 tunity of collecting migrating Wagtails in Egypt, and though 

 thousands pass through the Province of Giza, even within a 

 mile of the Zoological Gardens, I have seldom seen them 

 actually inside the walls.]
