306 Mr. 0. Salvin's Five Months' Birds' -nesting 



carefully eludes observation by skulking from bush to bush as 

 one approaches. In the above-mentioned shrubs it builds its 

 nest, making a loose but neat structure of dry grass with a 

 scanty lining of horsehair. The eggs in one nest seldom exceed 

 four. The Arabic name is " M'zizzee." 



38. Sylvia orphea. (Orphean Warbler.) 



This is a tolerably common bird about the wooded hill-sides 

 of Djendeli, where it usually breeds, though we sometimes ob- 

 tained nests from the tamarisk-trees in the plain. Its nest much 

 resembles that of the common Blackcap [S. atricapilla), but 

 differs in being more compact and thicker ; the position in the 

 branch of the tree selected is usually similar. The note of this 

 bird is pleasing, but hardly so much so as to entitle it to the 

 name of the Orphean Warbler. 



39. HiPPOLAis POLYGLOTTA. (Latham's Pettychaps.) 



A very common bird about the Chemora, where we found it 

 breeding in the tamarisk-trees. 



40. Phylloscopus rufus. (Chiff-chaff.) 



This was the first bird I heard on landing at Philippeville 

 before proceeding to Tunis. It appears to winter in Algeria. 

 I obtained specimens near El Djem in March. 



41. Phylloscopus trochilus. (Willow Wren.) 



During the month of March I shot moi'e than one of this 

 species in the Regency of Tunis. 



42. Phylloscopus sibilatrix. (Wood Wren.) 



I shot a single specimen of this bird (the only one I saw) 

 in May, near where the Chemora empties itself into Lake 

 Djendeli. 



43. Saxicola cenanthe. (Wheatear.) 



A specimen of this bird was shot near Zaua in June. 



44. Saxicola leucura. (Black Wheatear.) 



More abundant about the Djendeli district than elsewhere. 

 It appears to be an earlier breeder than other Saxicola, as young 

 were found at the end of May in an advanced stage.
