544 ZOOLOGY, 
quently brought into the market. The wild goose (Branta 
Canadensis) breeds in the North- 
ern United States and in British 
America. While it usually breeds 
on the shores of rivers, it has 
been known in Colorado and 
Montana to nest in trees. Allied 
to it is the barnacle goose of 
Europe (Branta leucopsis), which 
very rarely occurs in this coun- 
Fig. 466.— Carolina Rail.—From try, ‘The swans are characterized 
eee by their long necks, the trachea 
or wind-pipe being remarkably long, especially in the trum- 
peter swan, where it enters a cavity in the breast-bone, 
makes a turn and enters the lungs, 
after forming a large coil. 
To this group, or next to it, also 
belong the flamingoes, the American 
flamingo (Phenicopterus ruber) occur- 
ring on the Florida and Gulf coast.. 
Its feathers are scarlet, its bill yellow, 
large and thick, while the legs and 
neck are of great length. It connects 
the swimming with the wading birds. 
The foregoing group forms a division 
called the Natatores or swimming 
birds. We now come to the Gralla- 
zores or wading birds, which have long, 
naked legs, and therefore long necks, 
with usually remarkably long bills. 
They are divided into cranes, rails, etc. 
{Alectorides), the herons and their 
allies (Herodiones), and the shore-birds, 
snipes and plovers, or Limicole. 
The cranes, together with rails (Por- 
sana Carolina, Fig. 466) sometimes 
have lobate feet, the tues are often fig ie) Te cinlezel 
Jong, and in some forms, such as the 
coots and gallinules, there is an approach to the ducks.
