Late in spring we met with some migrating birds in S.E. Mongolia. 

 Ordos, and Ala-shan : in 1871 we observed them in S.E. Mongolia on the 9th 

 of May; in 1872, at Ala-shan, on the 20th of May. In autumn we noticed 

 them in the Hoang-ho valley toward the end of August, and at Ala-shan 

 during the month of September. In spring, as well as in autumn, these birds 

 were migrating only in small flocks of from three to ten specimens ; and by 

 reason of the scarcity of woods, they kept in the steppes and plains covered 

 with " sacsaulnics."

We met this beautiful Thrush (lately discovered by Pere David^ in 

 Si-chuaney) in the Kan-su mountains, where it inhabits the wooded localities. 

 Here it chooses the mountain- slopes covered with larch trees for its habitat 

 and nidification. It is very cautious in its habits, although it never gets 

 disturbed by man. In spring its song is beautiful, particularly early in the 

 morning and at sunset, from the branches of trees. The young begin to fly 

 about the end of June, and keep in families in those woods where plenty of 

 berries are found, and usually in the vicinity of mountain- creeks. 



We did not notice the time of their autumnal migration from Kan-su, 

 where they are rather common, and which, I find, is their northern limit.
