This Duck seems to be very widely extended in Eastern South 

 America from the north down to the extreme south. Schomburgk 

 found it abundant in the marshy savannas of British Guiana ; and 

 Natterer obtained specimens on the Rio Brancho. In S.E. Brazil 

 it is said by Prince Maximilian to be the commonest species of Duck. 

 According to Azara, Q. brasiliensis is much more abundant in Para- 

 guay than in Buenos Ayres. It is usually seen in pairs, but some- 

 times in flocks of twent} r , associating with other Ducks. He adds 

 that it moults in May and nests in August. 



Burmeister says this species is very common on the Parana and in 

 all marshes and lagoons of the northern districts. It is also common 

 at Tucuman. Mr. Darwin obtained specimens from Buenos Ayres in 

 October, and from the Straits of Magellan in February. 



Gay has inserted this species (like many others) in his list of Chilian 

 birds; but Philippi and Landbeck (Cat. Av. Chil. p. 42) state 

 that so far as they know it does not occur in that Republic. Gay's 

 specimen was probably from Bolivia, whence Salvin has obtained an 

 example.

Three Pintails are met with in the Neotropical Region. One of 

 these is the well-known European bird which penetrates in winter into 

 the northern portion of the region ; the others are endemic southern 

 species, one of which is sometimes separated as generically distinct.
