The two-barred warbler (Phylloscopus plumbeitarsus) is a bird of the leaf warbler family (Phylloscopidae). The species was first described by Robert Swinhoe in 1861. It was formerly included in the "Old World warbler" assemblage. It is closely related to the greenish warbler, to which it was formerly considered conspecific.
It is found in northern Mongolia, Manchuria and southern Siberia. They are a migratory species. Before the autumn migration, both adults and juveniles molt. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Two-barred Warbler is recorded against all the birds logged in Phnom Penh (41 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
