The Hypsipetes would have the black iris, orange to reddish beak, slightly forked tail, overall blackish, crest not always evident. Here we have the evident pale (light aquamarine iris), the bill is thicker at the base and shorter than Hypsipetes and yellow, the roundish and longish tail. OK. Let's try it again. Turdoides affinis taprobanus.
