FALCON. 65 



The female is almost wholly grey, having no white, except on 

 the rump, and that of a dirty colour. 



It makes the nest, for the most part, on the ground, among 

 lieath, fiirze, &c. but now and then upon pine and other high 

 trees, and generally lays three slate-coloured eggs. 



Said to be frequent in the southern parts of Russia, especially 

 about the rivers Don and Wolga, though not in Siberia. 



This species is used in falconry by the Calmucs.*
