THE BIRDS OF NORTHERN THAILAND 549 



from Ban Huai Horn or its neighborhood. I collected this flower- 

 pecker in Chiang Mai, Chiang Rai, and Nan Provinces, and only in the 

 last did I consider it to be a fairly common species; my series of 

 eight were taken at Ban Sop Mae Chaem, Muang Fang, Chiang Saen 

 Kao, Ban Wang Mo, and Ban Hai Huai Som. I have, in addition, 

 four sight records from Doi Suthep : One at 3,300 feet, July 20, 1929 ; 

 one at 3,600 feet, July 12, 1930; two at 3,300 feet, July 4, 1931; two 

 at 2,200 feet, October 31, 1931. 



This seems to be properly a bird of the more open lowland ever- 

 green, although, attracted by desirable flowers or fruits, it may enter 

 villages when these are at no great distance from the forest. To Doi 

 Suthep, where alone I have have found it at comparatively high 

 elevations, it seems to come only as an irregular visitor and, of the 

 July occurrences, two certainly (the third probably) were associated 

 with the antheses of an unidentified orange-flowered vine at the hill- 

 residence of H. M. the late Phraratchaya Chao Dara Ratsami na 

 Chiang Mai. Its notes and habits are those of the genus. 



A male from Ban Wang Mo, March 31, had the gonads enlarged. 

 A specimen from Ban Hai Huai Som, June 20, has not quite finished 

 the postnatal molt, while postnuptial molt is shown by a July example 

 from Muang Fang. 



An adult male had the irides orange; the maxilla black; the man- 

 dible plumbeous, tipped black ; the feet and toes slaty ; the claws horny 

 brown. 



Either sex has the entire upperparts olive-golden; the remiges 

 black, the primaries very narrowly edged with whitish, the secondaries 

 with inwardly increasingly broad margins of olive-golden; the 

 rectrices black; the lores white above and slaty below; a long white 

 mustachial streak, separated from the white chin and throat by a 

 slaty-olive stripe; the remaining underparts creamy white, boldly 

 streaked everywhere with olive-slate or slaty olive; the under tail 

 coverts orange-golden or golden-yellow; the under wing coverts and 

 axillaries white. 



D. c. chrysorrheum is easily separable from chrysochlore by its more 

 robust bill and by having the upperparts darker and duller, the 

 streaking below darker and bolder.
