PYRRHOCORAX PYRRHOCORAX (Linné). 
Eleven specimens, adults of both sexes and young, Tachienlu, and Cheto, 
western Szechwan, 9,000 to 12,000 feet, summer. 
The Chough was abundant in the high mountains in western Szechwan 
but was not met with in Hupeh. 
GRACULUS GRACULUS (Linné). 
Four adult males, Tachienlu, and Yachiakun, western Szechwan, 14,000 to 
15,000 feet, summer. 
The Alpine chough was decidedly rarer than the last species and occurred 
only at greater altitudes, from 14,000 feet or thereabouts, upward; still at these 
lofty elevations it was constantly seen flying about like a swallow and now and 
then settling in the villages to feed on Yak excrement.
