THE BIRDS OF NORTHERN THAILAND 301 



Northern birds belong to the form, intermediate between levaillantii 

 and macrarhynchos, which Mayr designates "Subsp. 2" (Ibis, 1940, 

 p. 695).

The paragraph dealing with the distribution in our provinces of 

 the ashy cuckoo-shrike (Coracina n. siamensis) applies equally well 

 to the white-eared jay, and, in fact, wherever one species is seen the 

 other may be expected to occur also. 



This bird is usually seen perched alone at the top of some high 

 tree, but where conditions are particularly favorable a number of 

 individuals may be in sight at once. I have more than once seen such 

 an informal gathering at the edge of a jungle grass fire, where the 

 jays were preying on the numerous small creatures driven out by 

 the flames. It is a rather noisy species, whose commonest note is a 

 rasping jay. 



I collected a male • with the gonads enlarged, March 7, and Gylden- 

 stolpe (1916) obtained at the end of May young birds still in com- 

 pany with the parents. Specimens taken between July 10 and 

 October 17 are in postnuptial molt. 



Adults have the irides brown; the bill black; the feet and toes 

 pale brownish gray or dusky flesh. 



The present species has the forehead white, each feather with a 

 black shaft streak ; the crown and rather short, rounded crest black ; 

 the scapulars and back vinaceous-brown, paler and more vinaceous on 

 the rump; the upper tail coverts white; the wings black, with the 

 shoulders chestnut, the remaining coverts narrowly barred black and 

 sky blue, the greater part of the outer web of the outer secondaries
