Descriptions
Identification
A single bird heard calling repeatedly. High pitched, sharp. I searched for the source while recording the sound on my handphone. I couldn't find it so I shared the recording with others to seek opinions which confirmed my suspicions that this was likely a Sakhalin leaf warbler, even without seeing the bird. Jen Wei and Raghav independently confirmed the frequency at the right level (roughly 4,700) for Sakhalin. Pale-legged should be about 5,700. Despite no sighting I'm submitting this due to the fact that this may be the earliest record for the species by over two weeks.
Habitat/behaviour
Calling from/behind thick cover. No views.
Viewing conditions
After an afternoon deluge. Overcast but light conditions irrelevant given no views.
Observer's experience

Observer's experience w/similar species
Pale-legged warbler seen and heard once in Singapore.
