304 GALLINA. TETRAO. Brack Grows. 
The species forming the first section are polygamous, and 
inhabit the forests of the mountainous and colder regions. 
The members of the second section usually pair, and the 
young birds continue with their parents till the following 
spring. They are natives of high northern latitudes, and of 
the highest mountains of central Europe. In some of the 
species belonging to this section, the moult is double, and 
the summer’s dress differs greatly from that of the winter 
months, which is assimilated to the snowy covering of the 
regions they inhabit. ‘The flesh of the birds of this genus is 
juicy, and of high flavour. 
SECTION I. 
With the tarsus only feathered. Edges of the toes deeply 
bordered with a fringed membrane.
