Claudia's leaf warbler (Phylloscopus claudiae) is a leaf warbler found only in China. Its natural habitat is temperate forests. Most taxonomists previously considered it to be a subspecies of the Blyth's leaf warbler. Olsson, U., P. Alström, P.G.P. Ericson, and P. Sundberg. 2005.

Rare
Under 5% of wildlife watchers report a Claudia's Leaf-Warbler sighting in Beijing on a given day, based on 84 verified sightings from GBIF citizen-science data. It is the 185th most-seen of the 324 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.
May
In that month about 10% of wildlife watchers report a Claudia's Leaf-Warbler in Beijing on a given day, against under 5% in June to April, the lowest months.
Between 2 and 5 am
Across all the parks we cover, that three-hour window holds the most Claudia's Leaf-Warbler sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Among the best
Of the 5 cities where we can rate Claudia's Leaf-Warbler sightings, Beijing ranks 4th at under 5%, level with the leaders once rounded. The best odds are in Hanoi (Vietnam, under 5%), Chengdu (China, under 5%) and Wuhan (China, under 5%).
Same genus: Phylloscopus
The closest relatives of the Claudia's 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 Claudia's Leaf-Warbler is recorded against all the birds logged in Beijing (84 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.
