all the while uttering a remarkably loud, ringing call. Its main food 

 is termites, in pursuit of which it may often be observed on rotting 

 stumps, logs, or even on the ground. 



I have no definite information on the breeding season but have a 

 series of eight juveniles collected between June 8 and August 24. 

 Molting adults have been taken from August 28 to November 9. 



Adult specimens had the irides lemon-yellow ; the orbital skin slate ; 

 the bill dark horny brown (horny black in the dried skin) ; the feet 

 and toes dull olive-green ; the claws slate. 



The male has the center of the crown shining red ; the rest of the 

 crown, the sides of the head, and the nape black ; the rump and lower 

 back deep scarlet; the remaining upperparts bright golden olive- 

 green ; the remiges and rectrices black, the former with broken white 

 bars on the basal half ; the throat, f oreneck, and sides of the lower neck 

 bright yellow, changing to greenish yellow on the breast, which color, 

 in turn, changes to whitish on the remaining underparts ; the feathers 

 of the lower breast, abdomen, flanks, and under tail coverts marked 

 with dull brownish V-shaped bars, which give a scaly appearance to 

 these parts. The female differs only in lacking the red crown patch. 

 Juveniles may always be recognized by their having the tips of the 

 primaries narrowly edged with white on the outer web.

In the North, the present species seems to be a rather uncommon but 

 well-distributed form. Eisenhofer sent to Stockholm a male taken at 

 Huai Pu, May 28, 1912, and another collected at Khun Tan in 1914. 

 I have examples from Chiang Mai, Chiang Rai, and Nan Provinces. 



Gyldenstolpe's type specimen was taken in "fairly dense evergreen 

 forest," but it is probable that bamboo was growing in the neighbor- 

 hood, for this woodpecker is partial to that type of growth beyond all 

 others. Near Chiang Mai is occurred chiefly in the extensive brakes 

 at the foot of Doi Suthep, less commonly in the deciduous forest of 

 the lower slopes to 2,000 feet, very rarely in town gardens. In Nan 

 Province it was frequently observed in clumps of giant bamboo along
