The first time I saw this Bulbul I knew it was but I was not pretty sure if what kind. It took me a lot of time comparing to all the Bulbuls posted on google, opening different sebsites just to know the given name. Well, Ochraceous Bulbul, it the given name and it is quite a big name for a Bulbul.
Ochraceous is another word for ocherous which means: 1.any of several earthy mineral oxides of iron occurring in yellow,brown, or red and used as pigments. 2. a moderate orange yellow, from moderate or deep orange tomoderate or strong yellow (http://www.thefreedictionary.com/ocherous).
