It was formerly included in the "Old World warbler" assemblage, and was usually (and sometimes is still) treated as a subspecies of the paddyfield warbler (A. agricola).

Rare
Under 5% of wildlife watchers report a Manchurian Reed Warbler sighting in Bangkok on a given day, based on 18 verified sightings from GBIF citizen-science data. It is the 239th most-seen of the 277 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Manchurian Reed Warbler in Bangkok on a given day, so our monthly data shows no clear season.
Yes
Of the 2 cities where we can rate Manchurian Reed Warbler sightings, Bangkok has the highest daily chance: under 5%. Next come Beijing (China, under 5%).
GBIF citizen-science records
It is estimated from how often the Manchurian Reed Warbler is recorded against all the birds logged in Bangkok (18 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.
