but when diflurbed, or whilft flying, he makes . 
a repeated noife of cuck, cock. They are 
moft common in winter at Albany Fort. 
Before I leave the genus of groufes, I muff 
obferve that their feet have a peculiarity, 
taken notice of by few authors ; the toes, . 
in feveral fpecies, have on each fide a row 
of fhort flexible teeth, like ihofe of a comb; 
fo that the toes appear pe&inated. The 
fpecies, which are known to have fuch pedti-- 
nated toes, are, 
1. The great Cock of the Wood, 'Tetrao , 
Urcgallus , Linn. 
2. The Black Cock, C T. Tetrix , Linn. 
3.. The Spotted Grous, f T. Canadenfis , 
and f T. Can ace , Linn, 
4. The Ruffed Grous, T. XJmbellm , Linn. 
5. The Shoulder-knot Grous, T. < Togatns i 
Linn. 
6 The Pheafant Grous, T. VhafianeUits . 
7. The Hazel Hen, T. Bonajia , Linn. 
8. The Pyrenaean Grous, T. Alchata , Linn. 
This is a circumflance, which ought to be at-- 
tended to in all other fpecies -of groufes, as it 
may in time afford a diflinguifhing character, 
for a divifion in this great genus; the ptar- 
migan, or T, Lagopus, Linn, is without thefe 
teeth.
