Phylloscopus warbler for ID: possible Two-barred Warbler

posted in: birds, Identification | 0

I saw this Phylloscopus warbler (dark green leaf-warbler) that was feeding on a caterpillar. The key features include:

  1. Two easily seen wingbars
  2. A long supercilium which is pale (hardly any yellowish)
  3. Lower mandible orange-yellow, upper mandible horn black
  4. No median crown stripe
  5. No yellow under the tail; very little yellow on underparts

I considered the commoner (for my region) Yellow-browed Warbler (Phylloscopus inornatus) but there is definitely no median crown stripe. The Greenish Warbler (Phylloscopus trochiloides) has not yet been recorded this far south but is a possibility; however there is limited yellow on the underparts. That suggests the Two-barred Warbler (Phylloscopus plumbeitarsus) which is considered a vagrant to my region. I have seen a similar bird on 23rd December 2007 in my Ipoh garden.

Note that feeding just 2-3 meters away from this bird was an ‘Arctic Warbler’ (unsure which one).

Appreciate any opinions.
