The grey-crowned warbler (Phylloscopus tephrocephalus) is a species of Old World warbler in the family Phylloscopidae. It is found in Bangladesh, China, India, Laos, Myanmar, Thailand and Vietnam. Its natural habitats are temperate forests, subtropical or tropical moist lowland forest, and subtropical or tropical moist montane forest.
The grey-crowned warbler was previously placed in the genus Seicercus. However, a molecular phylogenetic study published in 2018 found that neither Phylloscopus nor Seicercus were monophyletic. In the subsequent reorganization, the two genera were merged into Phylloscopus, which has priority under the rules of the International Commission on Zoological Nomenclature. Wikipedia →

Rare
Under 5% of wildlife watchers report a Gray-crowned Warbler sighting in Doi Inthanon National Park on a given day, based on 95 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 212th most-seen of the 367 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
February and April
In those months about 10% of wildlife watchers report a Gray-crowned Warbler in Doi Inthanon National Park on a given day, against under 5% in March and May–January, the lowest months. Those are among Doi Inthanon National Park's driest months, with about 65 mm of rain a month against 340 mm in August.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Gray-crowned Warbler sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 parks where we can rate Gray-crowned Warbler sightings, Doi Inthanon National Park ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Cuc Phuong National Park (Vietnam, under 5%).
Same genus: Seicercus
The closest relatives of the Gray-crowned Warbler that you can see in Doi Inthanon National Park (genus Seicercus) are Chestnut-crowned Warbler (about 20%) and Martens's Warbler (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Gray-crowned Warbler is recorded against all the birds logged in Doi Inthanon National Park (95 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.
