Both photos are form Huai Kha Kaeng Wildlife Sanctuary, taken back in August., pretty sure the ID for the first one is a juvenile white-rumped shama. A friend newly ID'ed the second one as white-rumped shama too, would you agree?
If my memory doesn't fail me, I would say it was pretty much average flycatcher size. I can't remember the length of the tail compared to rest of the body. I guess I have to leave this photo on my unidentified folder permanently..
