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 →

Rare
Under 5% of wildlife watchers report a Two-barred Warbler sighting in Bangkok on a given day, based on 191 verified sightings from GBIF citizen-science data. It is the 128th most-seen of the 277 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
November
In that month about 10% of wildlife watchers report a Two-barred Warbler in Bangkok on a given day, against under 5% in December to October, the lowest months. That is one of Bangkok's driest months, with about 40 mm of rain against 280 mm in September.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Two-barred Warbler sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is most active around dawn and dusk.
5th of 10
Of the 10 cities where we can rate Two-barred Warbler sightings, Bangkok ranks 5th at under 5%. The best odds are in Hanoi (Vietnam, about 10%), Beijing (China, about 10%) and Hong Kong (China, under 5%).
GBIF citizen-science records
It is estimated from how often the Two-barred Warbler is recorded against all the birds logged in Bangkok (191 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.
