Tetrao tetrix [Black Grouse].
Exists chiefly in the higher districts.
Tetrao Scoticus [Red Grouse].
Exists on all our moors and hills, but not in great numbers.
Tetrao lagopus [Ptarmigan].
Less frequent than either of the two last. Ptarmigans inhabit the summits of our highest mountains; they are seldomer seen than those which frequent the lower ground. Like all others of the grouse tribe, they are yearly decreasing in number.
Perdix cinerea [Partridge].
Pretty common. A very cunning and faithful mother is the female; for when she has eggs she never goes out, if time permits, without hiding them so carefully that it is almost impossible to detect their whereabouts; and if you take her by surprise, away she hobbles on one leg, and a wing trailing on the ground as if wounded. (See [p. 254].)
Perdix rufa [The Red-legged Partridge].
Commonly called the French Partridge; it has been recently found in Banff.
