It looks like a juvenile Common Tailorbird - small size, green back, rufous on crown, longish tail.

Looking again, and especially with the new photo, I think that I was wrong earlier. These look more like juvenile Plain Prinias. The new photo is in better light, and it is clear that the back is not green and the crown is not rufous. It also explains the slightly paler outer tail that was puzzling me before. Were there any adults around?
