Rare
Under 5% of wildlife watchers report a White-vented Myna sighting in Cat Tien National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 216th most-seen of the 244 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a White-vented Myna in Cat Tien National Park on a given day, so our monthly data shows no clear season.
Between 2 and 5 am
Across all the parks we cover, that three-hour window holds the most White-vented Myna 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.
9th of 9
Of the 9 parks where we can rate White-vented Myna sightings, Cat Tien National Park ranks 9th at under 5%. The best odds are in Kaziranga National Park (India, about 40%), Royal Manas National Park (Bhutan, about 20%) and Kaeng Krachan National Park (Thailand, about 20%).
GBIF citizen-science records
It is estimated from how often the White-vented Myna is recorded against all the birds logged in Cat Tien National Park (10 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.
