THE BIRDS OF NORTHERN THAILAND 303 



web of the primaries, the center of the abdomen, the under tail coverts, 

 and the tips of the rectrices are suffused with a beautiful but evanescent 

 pinkish-buff hue. 



The juveniles from Pak Chong, doubtfully recorded by Riley 

 (1938) as Urocissa flavirostris robini, are unquestionably of the pres- 

 ent species and can be matched in every detail by young birds that I 

 myself shot from flocks of K. e. magnirostris. 



A form of the common magpie (Pica pica) occurs in Kengtung 

 State within a few miles of our northern border and almost certainly 

 will be found, at least during the cold weather, in the Chiang Saen 

 district.

The hunting-crow is fairly common in all our provinces but is 

 restricted in range to districts of dense jungle, whether bamboo or 

 evergreen, in which it occurs both on the plains and on the hills to 

 about 5,000 feet. 



This species travels in small bands (accompanied on the plains by 

 Garrulax I. diardi, at higher elevations by Garrulax p. meridionalis 

 and Garrulax s. strepitans), which meticulously quarter the ground, 

 the thickets, vines, and trees. So heavy is the vegetation in which it 

 ordinarily dwells and so retiring the bird that it would seldom be 

 observed at all if it were not for its loud, harsh calls. On Doi 

 Suthep, where it was certainly present at all seasons, it appeared al- 

 ways to be much commoner in the rains and very rare during the 

 autumn months. 



An example with the gonads enlarged was taken on Phu Kha, April 

 7, and another in postnatal molt on Khun Tan, May 16. Specimens 

 collected between August 29 and November 28 are in postnuptial molt. 



Adults had the irides dark crimson; the eyelids yellowish brown, 

 edged with deep coral red; the bill, interior of the mouth, feet, and 

 toes deep coral red ; the claws horny orange.
