400 Mr. H. Duruford's Notes on the 



Theristicus melanopis. 



A few seen on the 10th November at the mouth of the 

 Sengel^ and subsequently observed in the Chupat valley. I 

 believe a few pairs were breeding on some swampy ground 

 in the latter place^ as I was informed that some large pale 

 bluish eggs had been found in the swamp where I had seen 

 the birds. I Avas unable, however, to trace them. 



^PhCENICOPTERUS IGNIPALLIATUS. 



Partially resident, but occurring in greatest numbers in the 

 winter. Common about Lake Colguape and the river Sengel. 



Bernicla magellanica. 



Winter visitant to the Chupat valley, arriving in March 

 and leaving in September. Resident about Lake Colguape, 

 where it breeds plentifully, laying seven or eight eggs in a 

 warm nest of down and feathers. We found the eggs excel- 

 lent eating. 



In the adult male the iris is wood-brown ; legs, feet, and 

 beak black. 



Bernicla poliocephala. 



Winter visitor to the Chupat valley, arriving and depart- 

 ing with B. magellanica, and always associating with that 

 species. It nests about Lake Colguape, in the same places as 

 B. magellanica. 



In the adult female the iris is orange ; beak black ; legs 

 orange, uppersides with a line of black ; feet and claws 

 black, the former with a little orange. 



^Cygnus nigricollis. 



Partially resident, but most numerous in the winter. These 

 birds were nesting in the reed-beds at the mouth of the Sen- 

 gelen; and the old birds were seen carrying the young on 

 their backs. Common up the Sengel as far as we went. 



*Cygnus coscoroba. 



Not observed at Chupat during my last visit, nor during 

 our journey to the lakes. 



^Querquedula cyanoptera. 



Resident, but rare. Seen once at the mouth of the Sengel.
