THE BIEDS OF MONGOLIA ETC. 153 



At Koko-nor we saw the first Kites on the 9th of March; but here they 

 were not so numerous as in Kan-su. The probable reason for this is the 

 scarcity of trees on the Koko-nor steppes. The autumnal migration from 

 Ala-shan and Kan-su takes place in September. 



In Ussuri country Milvus govinda is a very common bird, and many 

 specimens can be seen during a single day. About Lake Hanka the first 

 birds arrive between the 8th and 15th of March, and commence building in 

 April, constructing their nests not far from the ground, on large trees, and 

 close to the water, always avoiding great forests. As early as the middle of 

 April have I obtained eggs — two, or even three, in one nest. These are 

 marked, on a dirty white ground, with reddish brown spots and lines, which 

 are thickest at the ends. Largest diameter 2''* 21, smallest diameter l"*76. 



19. AsTUR PALUMBARius, L. Jastveh tetereviatnick. 



A young specimen has been obtained in autumn at Ala-shan. In S.E. 

 Mongolia it has been observed once or twice, but did not come under our 

 observation either at Koko-nor or in Kan-su. 



In Ussuri country this species is to be met with on the coast as well as 

 in the interior during summer. 



20. AcciPiTER Nisus, L. Jastreh perepeliatnick. 



Is plentiful in S.E. Mongolia and Kan-su, but has not been met with by 

 us in any other locality. In Ussuri country it is commoner than the preceding 

 species, and certainly leaves the interior of the country for the winter, but is 

 a resident on the coasts. At Hanka it appears in spring about the end of 

 March. 



The Coreans and Oroches train this, as well as the preceding species, 

 for sporting-purposes.
