Scientific Name: Phylloscopus borealoides
Malay Name: Cekup-Daun Kaki Pudar Jepun
Chinese Name: 库页岛柳莺
Found from the Japanese Archipelago, Sakhalin to Kuril islands and winters to Southeast Asia
Size: 11.5 cm
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. Can only be distinguished from the very similar looking Pale-legged Leaf Warbler in the field (which may also occur in Singapore) by its characteristic song.
Ecology/Behaviour: 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: Very rare migrant
Conservation Status: Least Concern (IUCN 3.1)
Location: Confirmed to winter in Singapore when two individuals were heard singing the characteristic song of the Sakhalin Leaf Warbler at a forested patch in Dairy Farm Nature Park in March 2014. Another record photographed at Lower Pierce Boardwalk in February 2009 cannot be identified conclusively as Sakhalin or Pale-legged Leaf Warbler.
