THE MOUNTAIN. 



DUCKS. 

 (Anas, Linn.) 



ANAS Boschas, (Rich.) Common duck, or mallard. This 

 duck, the original of the domestic species, has a range from 

 the Gulf of Mexico to the sixty-eighth parallel, and is said 

 to breed as far south as Pennsylvania. It is found also in 

 many parts of Europe. 



ANAS Discors, (Linn.) Blue-winged teal. This duck 

 passes the mountains of Pennsylvania in April, northward 

 bound, returning south late in September. Range, from 

 Guiana and West Indies to fifty-eighth parallel. These ob- 

 servations will also apply to the Buffel head. 



ANAS Sponsa, (Linn.) The Bride, or summer duck. A 

 species peculiar to America, and a constant resident in the 

 United States. Range, 45 north latitude to Mexico and 

 Antilles. This is the most beautiful of the ducks ; indeed, 

 few of the whole feathered tribe are so elaborately and ex- 

 quisitely ornamented as this bird. 



COLYMBUS Glacialis, (Linn.) Loon. This large water 

 bird has also a northern range. It stops on the mountain 

 in its migrations, and sometimes remains for several days, 

 slily slipping around the mill-dams and ponds. It is a hand- 

 some bird, and has a voice which is one of the most remark- 

 able sounds in nature.
