The Chinese leaf warbler (Phylloscopus yunnanensis) is a species of Old World warbler in the family Phylloscopidae. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical high-altitude shrubland. It is found only in China.
The Chinese leaf warbler's scientific binomial name, Phylloscopus yunnanensis, originates from the Irish ornithological naturalist authority John David Digues La Touche in 1922. A more recent Latin "junior synonym" alternate scientific name is P. sichuanensis from 1992. Yunnanensis and sichuanensis derive from the Yunnan and Sichuan provinces in China.
The Chinese leaf warbler is a brightly colored, small leaf-warbler, with a total length of around 10 cm and a wing length of 5–6 cm. Its body is slightly elongated and compact. The warbler has a slightly forked or notched tail that is almost square in shape. Its bill is pointed and short (around 1 cm long) and dark brown in color, brownish-yellow on the underside. The wings are very short and rounded, the legs slender and very dark. Claws and toes are dark brownish-grey with dusky buff undersides.

Rare
Under 5% of wildlife watchers report a Chinese Leaf-Warbler sighting in Beijing on a given day, based on 34 verified sightings from GBIF citizen-science data. It is the 239th 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 Chinese Leaf-Warbler in Beijing on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Chinese Leaf-Warbler sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 cities where we can rate Chinese Leaf-Warbler sightings, Beijing ranks 2nd at under 5%. The best odds are in Xining (China, about 10%).
Same genus: Phylloscopus
The closest relatives of the Chinese Leaf-Warbler that you can see in Beijing (genus Phylloscopus, Leaf Warblers) are Yellow-browed Warbler (about 20%), Pallas's Leaf-Warbler (about 20%) and Dusky Warbler (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Chinese Leaf-Warbler is recorded against all the birds logged in Beijing (34 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.
