42 Mr. H. Durnford on some Birds observed 



Erismatura ferruginea. 



A single bird shot on the 24th November in a ditch up 

 the valley, was the only one I saw, though I was informed it 

 was not uncommon. 



COLUMBA MACULOSA. 



Common throughout the valley, being found in flocks about 

 the wheat-stubbles, and breeding in the willows bordering the 

 river. 



FULICA LEUCOPYGA. 



Very common. Found on almost every piece of water in 

 the valley, but avoiding those where there is any current. 

 Breeds numerously in the neighbourhood of the village. 



Thinocorus rumicivorus. 



Common. Seen most frequently on the higher stony pla- 

 teaux, but occasionally in the valley. On the 3rd November, 

 whilst Guanaco-hunting, we flushed two from a patch of dry 

 sandy ground, some three hundred feet above the sea, and at 

 least twelve miles from any water. During my visit this 

 species was undoubtedly breeding in the neighbourhood, 

 though I did not discover any eggs. 



Vanellus cayennensis. 



Common throughout the valley, breeding whilst I was there. 

 Not seen on the hills. 



Oreophilus ruficollis. 



Common throughout the valley, frequenting the driest 

 ground, and occasionally seen on the hills. A pair, observed 

 on the 29th November in the dry bed of an old lagoon, 

 amongt coarse stunted grass, from their actions, I am in- 

 clined to think, were nesting, though my search for eggs was 

 unsuccessful. 



Phalaropus wilsoni. 



Common, swimming gracefully in the still pools formed by 

 the eddies of the river and in nearly all the adjacent stagnant 

 ditches. Usually seen in pairs. 



RnYNCHiEA SEMICOLLARIS. 



Rare. I observed a single bird on the 27th November on
