of the Delta of the Rhone. 189 



was also very abuudaiit in the Marais de Meyranne, near the 

 east bank of tbc Grand Rhone. 



AcROCEPHALUs TURDoiDES (Meyer). 



For some reason which we cannot explain, the Great 

 Reed- Warbler was abundant in the extensive marshes in the 

 north of tlie Camargue, but appeared to be entirely absent 

 from those of the south-west, though the latter were to all 

 appearance equally suitable as haunts. It was not uncommon 

 among willows on the banks of the Rhones, and was very 

 common in the reeds of the Marais de Meyranne. On the 

 canal near Aries one was observed singing in a poplar tree 

 quite twenty-five feet from the ground, 



LOCUSTELLA N.tVIA (Bodd.). 



The Grasshopper Warbler was only noted in some suitable 

 cover near the east bank of the Grand Rhone below Aries. 



Cettia cettii (Marm.). 



This species was very abundant in the northern portion of 

 the Camargue and in the neighbourhood of Aries, being con- 

 fined, however, to dense underwood fringing ditches. The 

 very remarkable notes of Cetti^s Warbler reminded us more 

 of the alarm-cry of a much-startled bird, rather than par- 

 taking of the nature of a song. This impression was further 

 heightened by the fact that on every occasion on which we 

 heard these notes — and they were many — they were uttered 

 only when we approached the bird's haunts and disturbed 

 its seclusion, and then, like a startled Blackbird, it instantly 

 burst out in its so-called song. 



CisTicoLA ccjrsitans (Fraukl.). 



A local species, which was observed only in the Marais du 

 Counn, and more abundantly in the Marais de Saliers, where 

 it frequented both the tamarisk-bushes and the reeds, and was 

 shot for identification. 



Panurus biarmicus (Linn.). 



The Bearded Reedling was found to be a local species, but 

 common where it occurred. In the Camargue we only 

 observed it in the dense reed-beds of the Marais du Couvin^
