of the Central Pyrenees. 75 



French Pyrenees at all moderate elevations^ hut missed it 

 among the wooded glens on the Spanish side. 



51. Embertza CIA, Linn. 



Common in the hedgerows around Eaux-Bonnes. We 

 lost sight of it on leaving the cultivated parts of the valley, 

 and did not recognize it at Argeles-Vieuzac or elsewhere. 

 This bird is very like the last species in its habits, and its 

 appearance on the wing or when perching suggests a case of 

 partial albinism in a Yellow Bunting, the yellow of the 

 head and neck being replaced by dirty white, but the note is 

 quite distinct. 



52. Alauda arboreAj Linn. 



On June 7th I saw a Wood- Lark among rocks and snow at 

 the summit of the Port de Gavarnie, 7485 feet. 



53. Alauda arvensis, Linn. 



On May 28th a single Sky-Lark was soaring above the 

 grassy downs near the Col de Saucede, about 5000 feet. I 

 do not think this species can be common in the Central 

 Pyrenees, for neither on the sheepwalks above and below 

 Eaux-Bonnes, nor in the meadows around Argeles-Vieuzac, 

 nor on the grassland about Torla, on the Spanish side, did 

 we see or hear it. 



54. Pyrrhocorax graculus (Linn.). 



55. Pyrrhocorax alpinus (Koch). 



We saw Red-billed Choughs on both sides of the frontier. 

 The well-known colony near St. Sauveur is still numerous, 

 and, I should think, likely to remain so. There are about 

 20 nests placed in inaccessible crevices in the sides of a 

 narrow wooded gorge. All are below the level of the road, 

 which winds along towards Gravarnie. The mountain- walls 

 seem almost to meet overhead ; the swift river, hundreds of 

 feet below, fills the whole bottom of the canon, which seems 

 only a gunshot in width. The sheer cliff-sides of the gorge 

 were hung with clematis and radiant with the wonderfully 

 rich flora of the Pyrenees, Ramonda blooming in every 

 crevice. The birds, secure in their unapproachable fastness,,
