Bombycilla garrula centralasie Poljakov. 
Bombycilla garrulus centralasie PousaKov, Messager Ornith., VI, April, 
1915, p. 137 (Zaissan district, southwestern slope of Altai Mountains, 
Turkestan, central Asia). 
Chars. subsp.— Similar to Bombycilla garrula garrula, but paler and 
somewhat less vinaceous (more cinnamomeus) above, particularly on back 
and cervix; also averaging less vinaceous below (more grayish). 
Measurements.— Male:+ Wing, 111-119 (average, 114.4) mm.; tail, 
59-63 (61); exposed culmen, 10.5-11.8 (11.3); tarsus, 20-20.5 (20.1); 
middle toe without claw, 16-17 (16.7). 
Type locality.— Zaissan district, southwestern slope of Altai Mountains, 
Turkestan, central Asia. 
Geographic distribution — Asia: Breeds in northern Siberia south at 
least to Vladivostok; winters south to Turkestan and central eastern China. 
Remarks.— Birds of this species from northeastern Asia differ 
from Bombycilla garrula garrula of Europe as mentioned by Polja- 
koy in his original description of Bombycilla garrula centralasia, 
and undoubtedly belong to the same form. This race, though to 
some extent intermediate between Bombycilla garrula garrula 
and the North American bird hereinafter separated as Bombycilla 
garrula pallidiceps, is nevertheless. worthy of recognition. The 
limits of the breeding range are at present unknown, but it is 
without much doubt the breeding bird of northern Siberia. We 
have examined a summer specimen from Vladivostok. The area 
of its intergradation with Bombycilla garrula garrula is probably 
somewhere in western Siberia, but this remains yet definitely to 
be determined. A specimen from Hsing-lung-shan, 65 miles north- 
east of Peking, China, taken February 12, 1915, is paler and much 
more grayish both above and below than other specimens of 
Bombycilla garrula centralasie, and may possibly be a wanderer 
from North America, but for the present it is referred to Bombycilla 
garrula centralasie. ‘Specimens of this subspecies have been ex- 
amined from also Tokio, Iwaki, and Hakodate, Japan; Shanghai 
and Peking, China; and Bering Island in the Commander Islands. 
1 Average of 6 specimens from Japan, Siberia, and China.
