This species breeds in Northern and Central Europe, and 

 winters in South-eastern Europe, Asia Minor, Persia, and 

 Africa. 



I found it common in Norway up to the North Cape, and in 

 North-east Russia to the mouth of the Petchora. Col. Irby 

 says that it breeds near Gibraltar (Ibis, 1872, p. 200). It 

 breeds in Transylvania [Dmiford and Harvie Brown, Ibis, 1 875, 

 p. 308) ; but Dr. Kriiper informs me that it is only found in 

 Greece and Asia Minor in winter. Its extreme eastern range 

 appears to be about long. 60° W. Its reported occurrence in 

 India seems in every instance to have been an error ; but it 

 occasionally winters in North-central and South-eastern 

 Persia {Blanford, Eastern Persia, ii. p. 180). Capt. Shelley 

 says that it winters in Egypt and Nubia (Ibis, 1871, p. 135). 

 Tristram says that it is abundant in the oases of North Africa 

 in winter (Ibis, 1859, p. 418). In the Strickland collection 

 at Cambridge is a skin from Kordofan, in Abyssinia ; and in 

 the British Museum are skins from the river Gambia, Damara 

 Land (Andersson), Cape-town [Layard], and Natal [An- 

 dersson) .
