Ornithology of the Egyptian Soudan. 323 



Blue Nile in which the bushes for a hundred yards on both 

 sides of a path, and for a distance of nearly half a mile, 

 were literally covered with their nests. There must at the 

 lowest computation have been many hundreds of thousands 

 of them.

What I have written about the numbers of the last species 

 applies equally well to the extraordinary abundance of this 

 on the White Nile. I see that Mr. Hawker wrote that he 

 " must have seen many millions,'" and I can guarantee that 

 there is no exaggeration. 



My specimens, in full breeding -plumage, were kindly 

 collected for me by Dr. Sukri Effendi Dib, of the Egyptian 

 Army. He told me that they were breeding in great 

 numbers during August in long grass at Fashoda. 



53. Oriolus galbula Linn. 



a. ? . Khartoum, Sept. 27, 1902. 



A very considerable immigration of Golden Orioles occurs 

 at Khartoum at the beginning of September, when the lime- 

 and fig-trees are full of them, mostly immature birds. After 

 this they pass on, and are comparatively scarce until March 

 and April, up to the end of which month they are abundant 

 again. I have never heard them utter their beautiful flute- 

 like notes in their winter-quarters. 



From Haifa in the north their migration follows the Nile 

 Valley up to Uganda. Gedaref is the most easterly point at 

 which I have observed it. 



54. BUPHAGA ERYTHRORHYNCHA (Stanl.). 



When creeping up to buffaloes in thick bush, at Jebel 

 Ahmed Aga on the White Nile, I have often heard the 

 sharp alarm-note of this species, and occasionally seen it. 

 Except in this one locality, I do not remember having met 

 with it.
