Bird-Life of Eastern Algeria. 145 



May 13, 1913. This species had not been recorded pre- 

 viously as breeding in North Africa until Graf Zedlitz took 

 a nest on May 22, 1913^ at the same locality. See Journ. 

 f. Orn. 1914, p. 139 (K). 



51. Phylloscopus collybita collybita (Vieill.). Chiffchaff. 

 Reported as beard on February 17, and heard on the 2oth 



at H. Meskoutine (W). (Several times Phylloscopi were 

 noted on migration, but as no specimens were obtained it is 

 inadvisable to record them.) 



52. Cettia cetti cetti (Marm.). Cetti^s Warbler. 

 Several seen and heard by the irrigation channels at 



Kroubs, April 17, 1912 (W). 



53. Acrocephalus arundinaceus arundinaceus (L.). Great 

 Keed-Warbler. 



Very common in the reed-beds on Lac Fetzara. Most 

 nests were still unfinished on May 1 (J). Nests ready for 

 eggs on May 4 and full clutches of four eggs on May 13- 

 15 (R). Heard and seen on April 11 (W). 



54. Acrocephalus streperus streperus (Vieill.). Reed- 

 Warbler. 



While working the banks of the Oued Biskra, near Bordj 

 Saada, I was much surprised to find many pairs of Keed- 

 Warblers in full song among the mixed reeds and tamarisks. 

 A careful search resulted in the discovery of an almost 

 finished nest, about five feet from the ground, in a tamarisk 

 bush. This is an extension of the breeding range of this 

 species, which has hitherto not been recorded as breeding 

 south of Ain Djendeli and Zana, and even there ^ith some 

 uncertainty, owing to confusion with A. aquuticus (J). 

 Breeds in small numbers on Lac Fetzara : nest with three 

 eggs on May 13, 1913 (R). 



55. Acrocephalus schcBnobaenus (L.) . Sedge- Warbler. 

 Song heard on Lac Fetzara, April 11, 1911 (W).
