I saw this darker looking ‘Asian Brown Flycatcher’ and considered M. d. williamsoni (Brown-streaked Flycatcher).
- David Wells (2007 & pers. comm. 2018) states that williamsoni “normally has an all-yellow, not black-tipped, lower mandible”.
- I reviewed all 15 images labelled as williamsoni (Brown-streaked Flycatcher) in OBI database and almost all have a clear black-tipped lower mandible. Also the same with birds in Singapore web sites and eBird images.
- Handbook of the Birds of the World (2020) on M. d. williamsonistates “more extensive dark area at tip of lower mandible”.
So I am inclined to go with a dark tip to the bill, including distal lower mandible.
This bird is browner that the nominate Asian Brown Flycatcher, has a pale buff eye ring (Wells), some pale brown streaks on breast/flanks.
Opinions welcome. Sadly no images of the wings, side or back.
