tion. The two species live together, and their habits are quite 

 similar. 



53. Aedon galactodes (Temm.). Rufous Sedge Warbler. 

 Has a curious habit of cocking its tail. It is hardly ever seen 



in any other position. Our common British Nightingale has 

 the same habit in a less degree ; but with the Rufous Sedge 

 Warbler it appears to be the natural posture to keep the tail 

 elevated ; in motion or at rest, it is only depressed at intervals. 

 As I saw scores of these birds on my return from the Mzab 

 country (in May), where there had not previously been one, 

 I conclude that the species is a summer migrant. Though 

 called by the name of " Sedge Warbler,'' it is any thing but 

 an aquatic bird. 



54. CisTicoLA scHCENicoLA (Bp.). Fautail Warbler. 



In the marsh at Laghouat, in small flocks. The inside of the 

 mouth is black in the male. 



55. Cettia sericea, Natt. Potamodus cettii (Marm.). 

 Cetti's Warbler. 



Is found equally in woods and in gardens, but always near a 

 ditch. Even in February it may be heard singing from the 

 heart of a bramble bush. Legs flesh-colour; inside of mouth 

 yellow ; eye dark brown. In appearance this bird seems inter- 

 mediate between a Whitethroat and a Wren. 



56. Philomela luscinia (Linn.). Nightingale. 



The first Nightingale I saw rose out of a field of young wheat ! 

 Later on they were plentiful, and one would, perhaps, hear three 

 or more singing at a time. The bird utters a hoarse croak if any 

 one is in the vicinity of its nest, but does not then swell out the 

 throat, which action, I suppose, always accompanies its well- 

 known song. The nest is made (in Algeria) of dead leaves and 

 large pieces of the stalk of a rush, but lined with finer material. 

 Some young ones found on the 21st of May scarcely showed 

 any feathers, but were able to see. 



Clinging sideways to any bough, the Nightingale can turn 

 head and body with equal facility, then pausing, right itself, as 

 it slowly raises its tail, at the same time di'ooping its wings until 

 they nearly meet at their points.
