The Indochinese roller (Coracias affinis) or Burmese roller, is a member of the roller bird family. It occurs widely from Nepal, eastern India to Myanmar and Southeast Asia. It is listed as Least Concern on the IUCN Red List.
The Indochinese roller was formally described in 1840 by the American naturalist Thomas Horsfield under the binomial name Coracias affinis based on specimens that had been collected in Assam by the naturalist John McClelland. The specific epithet affinis is from Latin adfinis or affinis meaning "related" or "allied".
McClelland has sometimes been credited as the authority but under the rules of the International Code of Zoological Nomenclature Horsfield now receives the credit. The Indochinese roller was formerly considered as a subspecies of the Indian roller because of a narrow hybrid zone in northeast India but a molecular phylogenetic study published in 2018 found that the Indochinese roller was more closely related to the purple-winged roller (Coracias temminckii) than it is to the Indian roller. The Indochinese roller is monotypic: no subspecies are recognised.

Likely
About 40% of wildlife watchers report an Indochinese Roller sighting in Yangon on a given day, based on 77 verified sightings from GBIF citizen-science data. It is the 22nd most-seen of the 66 birds we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
January–February and August–September
In those months about 50% of wildlife watchers report an Indochinese Roller in Yangon on a given day, against about 20% in October, the lowest month. April has too few records to rate.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Indochinese Roller 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.
Among the best
Of the 5 cities where we can rate Indochinese Roller sightings, Yangon ranks 2nd at about 40%, level with the leaders once rounded. The best odds are in Bangkok (Thailand, about 40%).
Same order: Coraciiformes
The closest relatives of the Indochinese Roller that you can see in Yangon (order Coraciiformes, Rollers, Kingfishers, and Allies) are White-throated Kingfisher (about 80%), Blue-tailed Bee-eater (about 20%) and Asian Green Bee-eater (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Indochinese Roller is recorded against all the birds logged in Yangon (77 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.
