With luck
About 10% of wildlife watchers report a Plain-backed Sparrow sighting in Bangkok on a given day, based on 1,364 verified sightings from GBIF citizen-science data. It is the 53rd most-seen of the 277 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
February to April
In those months about 20% of wildlife watchers report a Plain-backed Sparrow in Bangkok on a given day, against about 10% in May to January, the lowest months. Those are among Bangkok's driest months, with about 45 mm of rain a month against 280 mm in September.
Among the best
Of the 3 cities where we can rate Plain-backed Sparrow sightings, Bangkok ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Phnom Penh (Cambodia, about 10%).
Same genus: Passer
The closest relatives of the Plain-backed Sparrow that you can see in Bangkok (genus Passer, True Sparrows) are Eurasian Tree Sparrow (about 70%) and House Sparrow (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Plain-backed Sparrow is recorded against all the birds logged in Bangkok (1,364 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.
