species ranges up nearly to the limit of vegetation where 
it is a normal resident. I met it at about 3000 M. on Mt. 
Dempu, but was not able to shoot any, the birds being very 
shy : the only other species I saw in the same locality was 
Zosterops difficilis R. & K. On the summit of Mt. Talamau 
the only birds seen were this bulbul, Zosterops montana 
and Collocalia fuciphaga. In the alpine region it feeds 
on Vaccinium berries, but the two specimens, obtained on 
the plateau of Mt. Ophir (2800 M.), when there were no 
Vaccinium fruit, had the stomachs full of the seeds of 
Gahnia javanica Mor. They seem to breed there as one 
of the birds is young.
