1. It is reported in the paper that there are 173 species and 11 subspecies of birds which belong to 18 orders

41 families and 97 genuses. 2. The region of distribution of birds can primarily be devided into four vertical zones; 11 species of birds in high mountain (up 2300 m.)

107 species and 9 subspecies of birds in mountainous region (1100--2300m.)

92 species and 11 subspecies of birds in low mountain (1100-1700m.). 103 species and 9 subs- pecies of birds in flatlands (below 1000m). 3. Over 95 percent species of birds are typical palearctic species. Acording to the analysis of component parts of each zone

we agree with Mr. Ma Yong's suggestion. The Altai animal region should be European-Siberia subrealm

Altai subrealm of Altai-Sajan mountian range.
