Rare
Under 5% of wildlife watchers report a Manchurian Reed Warbler sighting in Beijing on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 315th most-seen of the 324 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 Beijing on a given day, so our monthly data shows no clear season.
Among the best
Of the 2 cities where we can rate Manchurian Reed Warbler sightings, Beijing ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Bangkok (Thailand, under 5%).
Same genus: Acrocephalus
The closest relatives of the Manchurian Reed Warbler that you can see in Beijing (genus Acrocephalus, Reed Warblers) are Oriental Reed-Warbler (about 10%) and Black-browed Reed Warbler (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Manchurian Reed Warbler is recorded against all the birds logged in Beijing (9 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.
