Possible
About 20% of wildlife watchers report a Red-whiskered Bulbul sighting in Ho Chi Minh City on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 45th most-seen of the 103 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
April and August
In those months about 30% of wildlife watchers report a Red-whiskered Bulbul in Ho Chi Minh City on a given day, against under 5% in February, May–July, September and November, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Red-whiskered Bulbul sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
40th of 65
Of the 65 cities where we can rate Red-whiskered Bulbul sightings, Ho Chi Minh City ranks 40th at about 20%. The best odds are in Hong Kong (China, about 90%), Kanpur (India, about 90%) and Tuen Mun (China, about 80%).

GBIF citizen-science records
It is estimated from how often the Red-whiskered Bulbul is recorded against all the birds logged in Ho Chi Minh City (14 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.
