It's a Minivet

I did make a mistake with this one, thinking that it's a flycatcher-shrike.  It's an Ashy Minivet, a migratory from the northern part of the world like China, Japan, even Siberia.  This bird feeds on seeds and fruits, and seen to forage mainly in the upper canopy of trees.  Hyper-active, it's also quite difficult to nail down.
