202 RED GROUSE. 
coverts were of a bluish grey cast, as was the -lower part 
of the breast: 16 was a young bird. Individuals are met 
with more or less variegated with white; others pale greyish 
yellow, faintly mottled with dusky: one mottled with brown 
and white was shot by Lord Stanley. Some birds are very 
dark, some have the quill feathers entirely or partly white. 
Sir William Jardine mentions one in which the quills were 
dull white, the ground colour yellowish white, the ° dark 
markings on it pale reddish brown.
