TETRAO 697 



Hal. The southern branches of the Ural range. 



In habits it is said to resemble Tetrao tetrix more than 

 T. urogallus, and its note is also said to differ from that of the 

 latter species.

$ ad. (Saglialien), General colour of plumage black ; head and neck 

 glossed with purplish blue, the breast with bottle-green ; upper parts dull 

 black, the scapulars, secondaries, and larger wing-coverts with terminal 

 white spot ; upper tail-coverts irregularly tipped with white ; under parts 

 brownish black slightly spotted with white, and indistinctly vermiculated 

 on the flanks ; tail uniform black, much graduated and long ; bill black ; 

 iris brown ; bare skin round the eye scarlet ; bill much smaller than in 

 T. uroyallus, 0'9 from the end of feathering to tip ; wing 15'3, tail 14'9, 

 the outer feather 4*2 shorter than the middle ones, tarsus 3'0 inch. The 

 female is distinguishable from that of T. urogallus not only by the white 

 on the scapulars, secondaries, and wing-coverts, and on the upper tail- 

 coverts, but by the long, greatly graduated tail. 



Hah The Transbaikal country to the southern portion of the 

 sea of Ochotsk ; the lower Amoor and the island of Saghalien ; of 

 rare occurrence in the mountains of the north of China. 



This Capercailly is said to differ considerably from T. urogallus 

 both in its play or " lek " and in its note, but it frequents the pine 

 forests like that species. Its "lek" is, however, almost always 

 performed, like that of T. tetrix, on the ground, and seldom on 

 a tree. The nest is a mere depression scratched in the ground, 

 and the eggs, which are deposited late in May, resemble those 

 of T. urogallus, but are more oblong in shape, and measure 

 about 2-38 by T60.
