Like Criniger gutturalis sordidus RicuM. this species is only a subspecific race of 
Criniger gutturalis from which it is separated merely by its larger size. 
It was fairly common in Northern Siam where it keeps to the evergreen forests as 
well as to the bamboo-jungles, but they, were only met with on localities where the vege- 
tation was very dense. They were mostly observed in couples or in small flocks. They 
have a smacking note often repeated when the birds have been disturbed in some way.

A fine series of this Bulbul was obtained at different parts of Northern Siam where 
it seems to be rather common in the dense evergreen jungles or in the mixed forests on 
the summits of the hills. It goes about in small parties and keeps to the highest trees 
where it searches for food among the leaves. It is as a rule very difficult to detect among 
the dense vegetation on account of its plain, protecting colouring.
