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 →

Rare
Under 5% of wildlife watchers report a Kamchatka Leaf Warbler sighting in Bali Barat National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 147th most-seen of the 173 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
January and February
In those months about 10% of wildlife watchers report a Kamchatka Leaf Warbler in Bali Barat National Park on a given day, against under 5% in March to December, the lowest months. Those are among Bali Barat National Park's wettest months, with about 260 mm of rain a month against 20 mm in August.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Kamchatka Leaf Warbler sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 parks where we can rate Kamchatka Leaf Warbler sightings, Bali Barat National Park ranks 2nd at under 5%. The best odds are in Komodo National Park (Indonesia, about 10%).
GBIF citizen-science records
It is estimated from how often the Kamchatka Leaf Warbler is recorded against all the birds logged in Bali Barat National Park (12 verified sightings from 2019 to 2026), 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.
