Rare
Under 5% of wildlife watchers report a White-vented Myna sighting in Hanoi on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 82nd most-seen of the 97 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.
February and September
In those months about 10% of wildlife watchers report a White-vented Myna in Hanoi on a given day, against under 5% in March–August and October–January, the lowest months.
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.
5th of 6
Of the 6 cities where we can rate White-vented Myna sightings, Hanoi ranks 5th at under 5%. The best odds are in Bangkok (Thailand, about 70%), Kuala Lumpur (Malaysia, about 10%) and Phnom Penh (Cambodia, about 10%).
GBIF citizen-science records
It is estimated from how often the White-vented Myna is recorded against all the birds logged in Hanoi (8 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.
