526 THE BIRDS OF HELIGOLAND 



322. Mallard [STOCKENTE]. 

 ANAS BOSCHAS, Linn. 



Heligolandish : the male Groon-hoaded G jour d. = Green-headed Drake. 

 The female Grii Enn = Grey Duck. 



Anas boschas. Naumann, xi. 576. 



Mallard. Dresser, vi. 469. 



Canard sauvage. Teuiminck, Mamiel, ii. 835, iv. 531. 



Like all fresh- water Ducks this species never occurs here in 

 large numbers, but only solitary examples are met with, both during 

 the autumn and spring migrations. During a long spell of severe 

 frost it also occurs during the winter months, such birds, however, 

 being invariably in a very emaciated condition. 



This generally known species, the ancestral parent of the 

 domestic Duck, breeds in central and northern Europe, and within 

 the same parallels of latitude throughout Asia and America, as 

 well as in Greenland ; it however, only in rare instances, advances 

 beyond the Arctic Circle. 



323. Pintail [SPIESSENTE]. 

 ANAS ACUTA, Linn. 1 



Anas acuta. Naumann, xi. 638. 



Pintail. Dresser, vi. 531. 



Canard a longue queue. Temminck, Manuel, ii. 838, iv. 532. 



This beautifully shaped Duck is but of very rare occurrence here; 

 as long as I have been observing, I have only met with five or six 

 examples, all, with but one exception, being old males. 



The breeding range of the species extends from Greenland and 

 Iceland through Europe, Asia, and America ; it is not found nesting 

 north of the Arctic Circle, nor does it extend further southward than 

 the latitude of central Germany. 



324. Gad wall [MITTELENTE]. 

 ANAS STREPERA, Linn. 



Anas strepera. Naumann, xi. 659. 



Gadwall. Dresser, vi. 487. 



Canard chipeau. Temminck, Manuel, ii. 837, iv. 532. 



I have only once seen an example of this species. The bird 

 had been shot by the eldest of the Aeuckens brothers, and was a 



1 Dafilu acuta (Linn).
