No. 28.—THE STREAM FOR WATER 
FOWL, 
in which some of the ducks and geese enumerated above, 
which require special care and seclusion for their welfare, are 
kept. 
The Summer or Wood T>\JCYi{Aix sponsa) of North Amer¬ 
ica, the beautiful Mandarin Duck {A. galericulata ) of China, 
the Common Teal ( Querquedula crecca ), and the Garganey 
Teal ( Q . circia ), both of Europe, the Green-winged Teal 
(Q. carolinensis ) and Blue-winged Teal (Q. discors) of 
our own country will be seen here. 
The summer duck differs from all the other true ducks of 
this country in its habit of living in trees,—its nest being 
commonly made in a hollow limb at a considerable distance 
from the ground. A group known as Tree Ducks are found 
through the warmer parts of the earth. The White-faced 
Tree Duck ( Dendrocygna viduatd), the Red-billed Tree 
Duck (Z>. autumnalis ), the Black-billed Tree Duck {D. 
arborea ), and the Indian Tree Duck (Z>. arcuata) are mem¬ 
bers of this group.

The true pheasants are indigenous to Asia and its islands ; 
but the matchless beauty of their plumage, and the delicate 
quality of their flesh, have caused some of them to be largely 
introduced into Europe and the United States. The bird 
now known as the English Pheasant (.Phasianus colchicus ) 
originally came from western Asia, and is believed to have 
been introduced into England about the close of the tenth 
century. It has long been perfectly naturalized, and is one 
of the most beautiful of the family. The Ring-necked 
Pheasant {Phasianus torquatus) has also long been domesti¬ 
cated in England, and has bred freely with the common 
pheasant; most of the birds known as ring-necked pheasants 
are the result of such a cross, in which the first-named bird 
seems to preponderate, the hybrids differing little in appear¬ 
ance from the original stock. Many of the pheasants have
