CACCABIS. — PERDIX. 313 



Anglia and the Midlands. It occurs in Yorkshire, but is 

 most numerous from Lincolnshire southwards to Essex and 

 in all the home counties as far west as Somersetshire. It has 

 been introduced with some success into parts of Wales, but 

 in the Orkneys, Scotland (except in Fife), and Ireland 

 similar attempts have not proved successful. 



General Distribution. — The Red-legged Partridge inhabits 

 south-western Europe, ranging northwards through France to 

 Belgium and south-west Switzerland, eastwards to northern 

 and central Italy, and southwards to Spain and Portugal, 

 where a rather darker and more richly coloured form, C. r. 

 Jdspanica, occurs. It is also found in the Balearic Islands, 

 Elba, and Corsica. In Madeira, Grand Canary, and the 

 Azores it has long been introduced.

 Distribution in the British Islands. — A Resident, generally 

 distributed in England and Wales and abundant in many 

 parts of Scotland, some birds habitually frequenting the 

 higher ground on the fringes of the moorland away from 

 arable land. In Ireland its numbers seem to be diminishing, 

 and in some parts it has entirely disappeared. In the Shet- 

 lands it is unknown : in the Orkneys and the Outer Hebrides 

 it has been introduced, but apparently not with success.
