My son (Firdaus) has been looking for this nest on and off for weeks. Look like this bulbul’s nest no longer active.
No eggs inside and the birds not attended to it.
This nest was at the top of mangosteen tree, very well hidden from side and top. He used the ladder to peeped inside. Studies show only 30% of nesting end successfully. Here the link to a very good photos and documentation about yellow-vented bulbul nesting. (Click here, by D. HO from NaturePhotographicSociety Singapore)
