About the Whistler's Warbler

Whistler's warbler (Phylloscopus whistleri) 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, from the Himalayas to Myanmar. Its natural habitats are subtropical or tropical moist montane forests and heavily degraded former forest.

Whistler's 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. The common name commemorates the English ornithologist Hugh Whistler (1889–1943). Wikipedia →

Before you go

What are the chances of seeing a Whistler's Warbler in Manas National Park?

Rare

Under 5% of wildlife watchers report a Whistler's Warbler sighting in Manas National Park on a given day, based on 35 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 260th most-seen of the 377 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.

When is the best time to see a Whistler's Warbler in Manas National Park?

February

In that month about 10% of wildlife watchers report a Whistler's Warbler in Manas National Park on a given day, against under 5% in March to January, the lowest months. That is one of Manas National Park's driest months, with about 40 mm of rain against 1070 mm in June.

What time of day is best to see a Whistler's Warbler?

Between 4 and 7 am

Across all the parks we cover, that three-hour window holds the most Whistler's Warbler sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.

Where does the Whistler's Warbler sighting chance come from?

GBIF citizen-science records

It is estimated from how often the Whistler's Warbler is recorded against all the birds logged in Manas National Park (35 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.
