YUHINA FLAVICOLLIS ROGERSI Deignan 



Phu Kha Ferruginous-collared Yuhina 



Yuhina flavicolln rogersi Deignan, Proc. Biol. Soc. Washington, vol. 50, 1937, 

 pp. 217-218 (Phu Kha, Nan Province, North Thailand). 



This bird is rather common in the humid evergreen between 5,000 

 and 5,500 feet (the summit) on Phu Kha, but it is not yet known from 

 any other locality. 



In forest so dark that only scattered ferns grew beneath the trees, 

 I found the yuhina usually perched quietly upon some high branch 

 but occasionally fluttering up a mossy trunk in the manner of Alcippe 

 castaneceps exul. In that remote upland jungle, where probably the 

 report of a gun had never yet been heard and where the smaller crea- 

 tures had no knowledge of man, it proved to be a bird almost without 

 fear. 



Specimens taken on April 10 and 11 had the gonads highly active. 



It has the forehead and crest dark brown ; the ear coverts and the 

 occiput, beneath the crest, gray-brown; a distinct nuchal collar, be- 

 ginning at the sides of the neck behind the ear coverts, ferruginous ; 

 the remaining upperparts olivaceous-brown; an incomplete eye ring 

 of pure white feathers ; the lores and a narrow mustachial streak, ex- 

 tending to the ferruginous collar, black ; the chin, throat, and center of 

 the breast and abdomen, white; the sides of the breast olivaceous- 

 brown with white streaks ; the flanks similar but gradually changing 

 to pale grayish fulvous on the under tail coverts.

The herpornis is common in the more open evergreen and the mixed- 

 deciduous forest throughout our provinces. On Doi Ang Ka and Doi 

 Khun Tan it has been recorded at 3,500 feet and on Doi Suthep, from 

 2,700 to 4,000 feet (rarely as low as 2,100 feet) ; in Fhrae and Nan
