The Kamchatka leaf warbler (Phylloscopus examinandus) is a species of leaf warbler (family Phylloscopidae). It was formerly included in the "Old World warbler" assemblage. It is closely related to the Arctic warbler and the Japanese leaf warbler, to which it was formerly considered conspecific.
It breeds in Kamchatka, Sakhalin, Hokkaido and the Kurile Islands; it migrates to Indonesia and the Philippines. The first European observation of a Kamchatka leaf warbler was made on July 18, 2021, in Kilpisjärvi, Enontekiö, Finland. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Kamchatka Leaf Warbler is recorded against all the birds logged in Hangzhou (38 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.
