I'm not sure that this species has been recorded on Pulau Tioman before but here is a link to some photos I took of an individual silent bird in the forest behind Melina Beach in the very early hours of Saturday morning last week.

I was there for a week or so and while I did not record many species of birds I did see plenty of colugos as well as a mouse deer, horsfield's flying squirrel and camera trapped a brush-tailed porcupine.
