According to Pastor Chr. Brehm Falco peregrinus grisei- 

 ventris breeds throughout Scandinavia (probably occasionally 

 in the plains and not in the mountains, where it is replaced 

 by a small variety of F. p. cornicum), and is found in Northern 

 Germany on migration. It does not breed in Central Russia, 

 but visits that country during the spring and autumn. A 

 very typical specimen of that bird from Novaja Zemlja is 

 in the Museum of Vienna. Two specimens, male from the 

 mouth of the Ussuri river and male from Kultuk, were pre- 

 sented by Messrs. Dybovsky and Gadlevsky to the Museum
