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.
