Likely
About 50% of wildlife watchers report a Hume's Warbler sighting in Jiuzhaigou National Park on a given day, based on 82 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 7th most-seen of the 131 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
May and June
In those months about 60% of wildlife watchers report a Hume's Warbler in Jiuzhaigou National Park on a given day, against about 20% in November, the lowest month. Those are among Jiuzhaigou National Park's wettest months, with about 150 mm of rain a month against 15 mm in December. January to March have too few records to rate.
Between 4 and 7 am
Across all the parks we cover, that three-hour window holds the most Hume's 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.
Yes
Of the 15 parks where we can rate Hume's Warbler sightings, Jiuzhaigou National Park has the highest daily chance: about 50%. Next come Keoladeo National Park (India, about 30%) and Bandhavgarh National Park (India, about 20%). All parks ranked.
Same genus: Phylloscopus
The closest relatives of the Hume's Warbler that you can see in Jiuzhaigou National Park (genus Phylloscopus, Leaf Warblers) are Buff-barred Warbler (about 50%), Sichuan Leaf-Warbler (about 50%) and Tickell's Leaf Warbler (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Hume's Warbler is recorded against all the birds logged in Jiuzhaigou National Park (82 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.
