The most pernicious natural enemy of the Grouse in 
Scotland and Ireland is the Grey Crow, but I should be 
sorry to preach a crusade of extermination even against 
this notorious egg-stealer, whose operations on a Grouse- 
moor would be very considerably curtailed by the pre- 
sence of a pair or two of resident Peregrines. The 
plumage of Grouse from different localities varies so 
greatly that to attempt to figure even a few of them 
would exceed any reasonable limits, and I think that 
my readers will allow that the Plate represents a fairly 
typical male bird.
