With luck
About 10% of wildlife watchers report a Hume's Warbler sighting in Royal Bardia National Park on a given day, based on 22 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 150th most-seen of the 233 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
January
In that month about 20% of wildlife watchers report a Hume's Warbler in Royal Bardia National Park on a given day, against under 5% in April–July, September and December, the lowest months. That is one of Royal Bardia National Park's driest months, with about 35 mm of rain against 590 mm in July. August has too few records to rate.
Between 4 and 7 am
Across all the parks we cover, that three-hour window holds the most Hume's 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.
12th of 15
Of the 15 parks where we can rate Hume's Warbler sightings, Royal Bardia National Park ranks 12th at about 10%. The best odds are in Jiuzhaigou National Park (China, about 50%), Keoladeo National Park (India, about 30%) and Bandhavgarh National Park (India, about 20%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Hume's Warbler is recorded against all the birds logged in Royal Bardia National Park (22 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.
