334 Mr. A. L. Butler on the 



scrub. It is a pleasing and active little bird, looking something 

 like a Blackbird in miniature as it hops about on the grouud 

 with its tail raised, and is a cheery and persistent songster. 

 In flight the brown on the primaries and the white spots on 

 the expanded tail are conspicuous. It is almost always 

 found in pairs. It ranges at least as far north as the Atbara, 

 all up the Blue Nile and across to the Setit, and westwards 

 right through Kordofan. I do not know whether it reaches 

 further south than Kaka or Fashoda on the White Nile. 



I took two clutches, of two and three eggs, on the Setit 

 on May 6th and 12th, 1903. The nests were like Robin's, 

 and placed in crevices in tree-trunks. 



89. Acrocephalus turdoides (Meyer). 



The Great Reed- Warbler seems to pass through the 

 country southwards in September. In that month I have 

 seen it on three or four occasions in reed-beds on the White 

 Nile and in "dhurra" crops at Khartoum. I should call it 

 a rare bird in the Soudan. 



90. Acrocephalus streperus (Vieill.). 

 a. S t Kamlin, Blue Nile, March 1901. 



The Common Reed-Warbler is a fairly abundant species 

 in the winter and spring. I have shot it as far east as 

 Gallabat and as far west as El Obeid in Kordofan. 



91. Acrocephalus phragmitis (Bechst.). 



The Sedge-Warbler is occasionally, but rarely, met with in 

 the winter. On two occasions I have been able to watch the 

 bird through glasses in gardens at Khartoum, and I am pretty 

 sure of the identification, though I have not shot specimens. 



92. Hypolais pallida (Hempr. & Ehr.). 



a. S- Khartoum, Nov. 11, 1902. 



b. S- „ Feb. 10, 1902. 



c. ? . Gedaref, May 1, 1901. 



Quite the most abundant of the migratory Warblers in 

 winter and spring.
