Geographical distribution — British: The Eed-legged Partridge was 

 introduced into England in 1770 by the then Marquis of Hertford and Lord 

 Eendlesham, -who turned out chicks in Suffolk. It is chiefly distributed over the 

 eastern counties of England: Norfolk, Suffolk, Essex, Kent, and Sussex; only 

 occasionally elsewhere, owing to its partiality for dry, sandy soils ; but there is 

 evidence of it increasing its area over the Midlands, Lincolnshire, and the higher 

 grounds north of the Thames Valley. Attempts have been made to introduce 

 this bird into Scotland and Ireland, but with small success, climatic conditions 

 probably being the principal cause of failure. Foreign: South-west Europe. It 

 is most commonly distributed in South and Central France, Portugal, Spain, the 

 Balearic Islands, Corsica, Elba, North and Central Italy, Switzerland, and Savoy. 

 It becomes much more local and rare in Northern Prance, Belgium, and the 

 districts lying round its usual habitat. It has been introduced into Madeira and 

 the Azores, and is found in Gran Canaria. 



Allied forms. — Caccabis petrosa, an inhabitant of North-west Africa, the 

 Canaries, Gibraltar, and Sardinia. Differs from the Eed-legged Partridge in 

 having the nape and collar brown. C. saxatilis, with vars. chukar and magna, 

 range from the Alps to North China. Differs from the Eed-legged Partridge in 

 being larger and paler, and in having the throat and lores buff (chukar) ; neck-band 

 double; throat buff, but lores black [magna). A darker and more richly coloured 

 form of the Eed-legged Partridge, occurring in Spain, has been separated under 

 the name of Caccabis rufa hispanica.
