Blyth's leaf warbler (Phylloscopus reguloides) is a species of leaf warbler (family Phylloscopidae). It was formerly included in the "Old World warbler" assemblage. It is found mainly in Southeast Asia, southern China and along the Himalayas till northern Pakistan. Its natural habitat is subtropical or tropical moist montane forests.
This bird was named after the English zoologist Edward Blyth. In regard to its birdsong complexity, which takes into account the number of distinct notes, Blyth leaf warbler's high complexity is a consequence of increased variation between song types. Wikipedia →

Rare
Under 5% of wildlife watchers report a Blyth's Leaf-Warbler sighting in Jim Corbett National Park on a given day, based on 14 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 301st most-seen of the 368 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 Blyth's Leaf-Warbler in Jim Corbett National Park on a given day, so our monthly data shows no clear season.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Blyth's Leaf-Warbler sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
8th of 8
Of the 8 parks where we can rate Blyth's Leaf-Warbler sightings, Jim Corbett National Park ranks 8th at under 5%. The best odds are in Doi Inthanon National Park (Thailand, about 30%), Langtang National Park (Nepal, about 20%) and Namdapha National Park (India, about 20%).

GBIF citizen-science records
It is estimated from how often the Blyth's Leaf-Warbler is recorded against all the birds logged in Jim Corbett National Park (14 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.
