The clear yellowish undersides and lack of a wing bar can be used to tell it apart from similar species. It has slim dark legs with largely pale lower mandible and grayish wing panel.

Rare
Under 5% of wildlife watchers report a Tickell's Leaf Warbler sighting in Namdapha National Park on a given day, based on 26 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 212th most-seen of the 298 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.
March
In that month about 10% of wildlife watchers report a Tickell's Leaf Warbler in Namdapha National Park on a given day, against under 5% in April–May and October–February, the lowest months. That is one of Namdapha National Park's driest months, with about 120 mm of rain against 660 mm in July. June to September have too few records to rate.
Between 4 and 7 am
Across all the parks we cover, that three-hour window holds the most Tickell's Leaf Warbler sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is most active around dawn and dusk.
10th of 15
Of the 15 parks where we can rate Tickell's Leaf Warbler sightings, Namdapha National Park ranks 10th at under 5%. The best odds are in Jiuzhaigou National Park (China, about 30%), Eravikulam National Park (India, about 30%) and Langtang National Park (Nepal, about 20%).
Same genus: Phylloscopus
The closest relatives of the Tickell's Leaf Warbler that you can see in Namdapha National Park (genus Phylloscopus, Leaf Warblers) are Blyth's Leaf-Warbler (about 20%), Yellow-browed Warbler (about 10%) and Yellow-vented Warbler (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Tickell's Leaf Warbler is recorded against all the birds logged in Namdapha National Park (26 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.
