PSITTIPARUS, 119 



Measurements. Wing 86 to 89-5 mm. ; tail about 78 mm. ; cul- 

 men 12 to 13 mm. long but only 9 to 9*5 mm. deep at the base ; 

 tarsus about 25 mm. 



Distribution. Hills vSouth of the Brahmaputra, Chin, Kachiu 

 Hills and hills of Central Burma. 



Nidification. Cannot be distinguished from that of the lied- 

 headed Parrot-Bill in any way. 88 eggs average 20*7 X 16-2 mm. 



Habits. Similar to those of P. r. haheri, but is perhaps not 

 found at such low elevations. It occurred in the low hills round 

 Margharita in Assam, but here the close proximity of the snow- 

 line gives an avifauna and flora at 700 to 1,000 feet which obtains 

 elsewhere at more than twice this height. It is curious that 

 though all the Red-headed forms of Parrot-Bill consort together 

 when feeding, none of the red-headed birds are ever found mixing 

 with those of the grey-headed races.
