“Tris dark hazel, bill black, feet black or greenish black.” 
The Yellow-vented Bulbul was fairly common in second- 
ary jungle and waste land both in the Korinchi Valley and on 
the West Sumatran Coast, though it was never met with in 
primaeval forest. It was, however, not nearly so abundant 
as in the Malay Peninsula, where it is one of the commonest 
of garden birds. 
Sumatran and Malay Peninsula birds differ in no respects.
