With luck
About 10% of wildlife watchers report a Red-whiskered Bulbul sighting in Chattogram on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 55th most-seen of the 76 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
March
In that month about 30% of wildlife watchers report a Red-whiskered Bulbul in Chattogram on a given day, against under 5% in October, the lowest month. That is one of Chattogram's driest months, with about 40 mm of rain against 780 mm in July. April and July–August have too few records to rate.
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.
48th of 65
Of the 65 cities where we can rate Red-whiskered Bulbul sightings, Chattogram ranks 48th at about 10%. The best odds are in Hong Kong (China, about 90%), Kanpur (India, about 90%) and Tuen Mun (China, about 80%).
Same order: Passeriformes
The closest relatives of the Red-whiskered Bulbul that you can see in Chattogram (order Passeriformes, Perching Birds) are Indian Pied Starling (about 80%), House Crow (about 70%) and Striated Grassbird (about 60%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Red-whiskered Bulbul is recorded against all the birds logged in Chattogram (6 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.
