Chestnut-vented (a split from Ochraceous) is supposed to be a montane species. Did you see this one at Sepilok, Stuart? Any more images of that one?

An innocent question as I have no field experience with these birds but will be in Sabah later this year - why would that be a Chestnut-vented Bulbul instead of Gray-cheeked or Puff-backed, especially given location?
 
Yes, Josh, the 3rd bird is a Puff-backed. I overlooked it on the Avibase checklist for Sepilok. I first looked at the images on my phone and my first impression was Ochraceous, which was why I got sidetracked. A view of the underparts would have resolved this one very quickly (clean white on Puff-backed, ochre - hence the name - on Ochreaceous). Ochraceous has a warm brown crest and nape, not dull grey-brown as in Puff-backed. If you look closely at the OP bird, you can see the trousers are whitish, not yellow-brown as they would be on Ochreaceous.

Grey-cheeked does occur here too and is superficially similar to both species but differs in its flatter crest, less puffy throat, greenish mantle and breast and yellow belly - it has much more varied plumage.

Thanks much for the explanation!
 
Thanks for sorting that one out! I definitely need to spend more time there looking at Bulbuls (chance would be a fine thing). ;)
