Brown-streaked Flycatcher Muscicapa williamsoni ?

posted in: birds, Miscellaneous | 0

I saw this darker looking ‘Asian Brown Flycatcher’ and considered M. d. williamsoni (Brown-streaked Flycatcher).

  1. David Wells (2007 & pers. comm. 2018) states that williamsoni “normally has an all-yellow, not black-tipped, lower mandible”.
  2. 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.
  3. 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.
