The buff-throated warbler (Phylloscopus subaffinis) is a species of leaf warbler (family Phylloscopidae). It was formerly included in the "Old World warbler" assemblage. It breeds in China and winters down toward northern Southeast Asia. Its natural habitat is temperate forests.
Its underparts are yellowish, and its upperparts are greenish-gray. Its bill has a dark tip. It is similar to the Tickell's Leaf Warbler, but duller in color. It can be identified by its short two-note call. It forages in low vegetation.
It breeds on hillsides in open scrub habitat. Wikipedia →

Rare
Under 5% of wildlife watchers report a Buff-throated Warbler sighting in Chengdu on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 129th most-seen of the 156 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.
February
In that month about 10% of wildlife watchers report a Buff-throated Warbler in Chengdu on a given day, against under 5% in March to January, the lowest months. That is one of Chengdu's driest months, with about 15 mm of rain against 270 mm in August.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Buff-throated 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.
Only Chengdu, in our data
Chengdu is the only city on Wallace's Line with enough records to rate Buff-throated Warbler sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Phylloscopus
The closest relatives of the Buff-throated Warbler that you can see in Chengdu (genus Phylloscopus, Leaf Warblers) are Pallas's Leaf-Warbler (about 20%) and Yellow-browed Warbler (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Buff-throated Warbler is recorded against all the birds logged in Chengdu (6 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.
