Phylloscopus tenellipes
Family: Leaf Warblers · Status: Vagrant · Size: 11.5 cm · Conservation: Least Concern
Breeds from North Korea to southeast Russia and northern South Korea, wintering to Indochina and northern Thai-Malay Peninsula. Precise wintering range unclear.
Resembles Arctic Warbler but has a dark greyish crown contrasting with olive-greenish mantle, warmish olive-brown rump, two buffish wing bars, and pale greyish-pink legs and feet. Prominence of wing bars and dullness of upperparts both variable. Short stout bill. Visually indistinguishable from Sakhalin Leaf Warbler; separable in the field only by call (higher frequency in Pale-legged Leaf Warbler; ~6 kHz vs ~5 kHz) or song, though the latter is unlikely to be heard in Singapore.
Forest and forest edge; also found in lowland scrub and mangroves on passage.
Forages for insects from the forest floor to the canopy, also in low shrubs and vines.
