The green-crowned warbler (Phylloscopus burkii) is a species of leaf warbler (family Phylloscopidae). It was formerly included in the "Old World warbler" assemblage. It is found in the Indian subcontinent, ranging across Bangladesh, Bhutan, India, Nepal, and Pakistan. A single sighting was recorded from Sigiriya, Sri Lanka in 1993. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests.
The green-crowned warbler was previously placed in the genus Seicercus. 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 Golden-spectacled Warbler sighting in Royal Manas National Park on a given day, based on 39 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 216th most-seen of the 388 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.
January and April
In those months about 10% of wildlife watchers report a Golden-spectacled Warbler in Royal Manas National Park on a given day, against under 5% in February–March, May–July and October–December, the lowest months. Those are among Royal Manas National Park's driest months, with about 110 mm of rain a month against 930 mm in July. August and September have too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Golden-spectacled 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.
2nd of 3
Of the 3 parks where we can rate Golden-spectacled Warbler sightings, Royal Manas National Park ranks 2nd at under 5%. The best odds are in Langtang National Park (Nepal, about 10%).
Same genus: Seicercus
The closest relatives of the Golden-spectacled Warbler that you can see in Royal Manas National Park (genus Seicercus) are Chestnut-crowned Warbler (about 10%), Gray-cheeked Warbler (about 10%) and Whistler's Warbler (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Golden-spectacled Warbler is recorded against all the birds logged in Royal Manas National Park (39 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.
