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 Kolkata on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 245th most-seen of the 247 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Golden-spectacled Warbler in Kolkata on a given day, so our monthly data shows no clear season.
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.
Among the best
Of the 5 cities where we can rate Golden-spectacled Warbler sightings, Kolkata ranks 5th at under 5%, level with the leaders once rounded. The best odds are in Tamluk (India, under 5%), Lucknow (India, under 5%) and Jabalpur (India, under 5%).
GBIF citizen-science records
It is estimated from how often the Golden-spectacled Warbler is recorded against all the birds logged in Kolkata (5 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.
