484 Mr. P. E. Blaauw : Field-notes on some 



as the bird gets older, inclines to extend itself. This is hot 

 the case with C. inornata, which is and remains ptriped, 

 even in extreme old age. 



Although isolated specimens of this species may occasion- 

 ally wander to other places, it seems likely that it is peculiar 

 to the Falklands and has its true habitat there, whilst every- 

 where else in South America, in Tierra del Fuego and its 

 adjacent islands, and on the mainland, the usual form is 

 C. inornata. 



Chloephaga poliocephala. 



I was told in Tierra del Fuego that the Ashy-headed 

 Goose is a scarce summer visitor to the island, breeding 

 there in small numbers. In autumn it is said to sometimes 

 associate with the flocks of Chloephaga rubidiceps. 



I myself did not see a single example, although I could 

 approach the flocks of C. rubidiceps close enough for inspec- 

 tion. Nor did I see any by themselves. 



On the mainland, behind Punta Arenas, it is also said to 

 breed, and in the Museum of Padre Borgatello of that town 

 were some specimens that had been obtained during the 

 breeding-season in the neighbourhood. 



In Chiloe this bird is said to be abundant in some seasons 

 and to breed there. In Puerto Montt I saw a female in 

 confinement which was said to have been obtained in Chiloe. 



Chloephaga ruhidiceps. 



This pretty little Goose is a very common inhabitant 

 of Tierra del Fuego, although its numbers are not to be 

 compared to those of Chloephaga inornata. 



It is a summer visitor to the island, and leaves in April to 

 spend the winter in the north on the mainland of Patagonia. 

 I saw large flocks near Jente Grande and Estancia Sarita, 

 about the 11th of April, ready to leave. The birds were 

 quite tame. 



The English settlers call these Geese " Brent." 



In the Museum of Padre Borgatello at Punta Arenas were 

 several specimens from that neighbourhood, where they also 

 breed.
