GREY-FRONTED GREEN PIGEON 39 



wherever found, it is resident, merely moving higher up the hills 

 in the hot weather and rains. BourdiUion says that it ascends as 

 high as 3,000 ft. in Travanoore, but Davison, possibly referring 

 to other months, says that it does not ascend the hills at all. 

 Though common enough in some parts of its distribution, the Grey- 

 fronted Green Pigeon seems nowhere to be found in as vast numbers 

 as is the Ashy-headed Green Pigeon. It collects also in rather smaller 

 flocks, generally of half a dozen or so, and there appear to be no 

 record of flocks much over twenty. Mr. F. W. BourdiUion says that 

 it " may be found in great numbers in the neighbourhood of the hiU- 

 men's clearings, but in February and March they ascend the hills 

 to over 2,000 ft. Their note is a low chuckling whistle." 



This description of their call would, however, apply only to some 

 of their notes, as other writers describe their whistle as a most beautiful 

 and melodious sound, apparently much hke that made by the other 

 birds of this genus.
