My first long trip in 2010 to Taman Negara Kuala Koh was simply "paradise" and managed to sight just under 40 species of birds and those that I have "heard" are not accounted for. Anyway, long story short, I was blessed with the sighting of the Asian Paradise Flycatcher on many occasions, the White Morph, Dark Morph and the sub adult male without its long central feathers tail. Only managed to photograph the white morph and the sub adult but not the Dark Morph long-tailed, next time may be.
The white morph Asian Paradise Flycatcher is simply stunning and is one of most beautiful bird of Malaysia, at least that is what I think.
There are two very interesting articles about ASian Paradise Flycatcher here that you should not missed.
