The orange-bellied leafbird is common on all the higher peaks of 

 the North (including Phu Kha), ranging through the evergreen from 

 4,500 to 5,500 feet and occasionally seen as low as 3,000 feet. On Doi 

 Suthep, where it may be observed in large and noisy flocks at flow- 

 ering trees, it is one of the most conspicuous birds of the higher 

 ridges. 



The relationships between our three species of Chloropsis and cer- 

 tain showily flowering trees are noteworthy, and it seems certain 

 that, although attracted to the blossoms solely for the purpose of 

 feeding upon nectarivorous insects, these birds inadvertently play an 

 important part in cross pollination. 



A specimen from Doi Ang Ka, April 12, had the gonads enlarged. 

 Examples in postjuvenal molt were taken at various localities between 

 August 12 and November 17 ; in postnuptial molt, between August 13 

 and November 23. 



Adults have the irides brown; the bill black; the feet and toes 

 plumbeous-blue or dark plumbeous; the soles yellowish gray; the 

 claws horny black or blackish brown. 



The old male has the forehead and sides of the crown greenish yellow, 

 the remaining upperparts deep green, more or less suffused with yellow
