Though found in the extreme south of England, the Black 
Grouse more properly belongs to the low birch-woods and heaths 
of the less elevated districts of Scotland. It breeds “ occasion- 
ally?” in Cornwall (Mr. EH. H. Rodd). In Devon, Somerset, 
Dorset, Hants, Sussex, Surrey, Berks, Worcester (Yarrell), 
Shropshire, Stafford, Radnor (Mr. Rocke), North Wales “in- 
troduced and decreasing on the Beswyn mountains near Corwen” 
(Eyton), Cheshire, Lancashire, and both divisions of Yorkshire, 
and in all districts to the north of these, extending to Islay, 
Mull, Skye, &c., but not reaching the Outer Hebrides, nor is 
it found in Orkney or Shetland. 
The Black Grouse has been successfully introduced in the 
neighbourhood of Lynn in Norfolk. Yarrell says that the pro- 
cenitors of the birds at present inhabiting the heaths of Surrey 
and Berks were brought from Holland, though the species had 
previously been known as indigenous to the former county. A 
single nest found in Northamptonshire is recorded by Lord Lil- 
ford (Zoologist, p. 8278). 
Mr. Selby describes the Black Grouse as increasing in North- 
umberland ; and the same circumstance has been noticed coin- 
cident with the increase of plantations in several parts of Scot- 
land. As Thompson remarks, the Black Grouse might probably 
be introduced to Ireland, but the attempts hitherto made have 
been unsuccessful.
