Scientific Name: Phylloscopus tenellipes
Malay Name: Cekup-Daun Kaki Pudar Barat
Chinese Name: 淡脚柳莺
Range: Breeds from North Korea to Southeast Russia and winters in Southeast Asia. Precise wintering range rather unclear.
Identification: Adult resembles Arctic Warbler but has dark greyish crown contrasting with olive-greenish mantle, warmish olive-brown rump and pale greyish pink legs and feet. Indistinguishable from the very similar looking Sakhalin Leaf Warbler visually (or oftentimes even in hand), and in the field it can only be told apart by its call (~6Khz instead of ~5Khz) or characteristic song.
Behaviour/Ecology: Usually forages for insects on the forest floor, sometimes climbing up low shrubs and vines to glean prey. May also be found in the mid-storey to canopy levels.
Local Status: Vagrant
Conservation Status: Least Concern (BirdLife International 2016)
