The ruby-cheeked sunbird (Chalcoparia singalensis) is a species of sunbird in the family Nectariniidae. The ruby-cheeked sunbird was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the wagtails in the genus Motacilla and coined the binomial name Motacilla singalensis. Gmelin erroneously specified the type locality as Ceylon (now Sri Lanka) where the species does not occur. The locality was designated as Malacca on the Malay Peninsula by the American ornithologist Harry C. Oberholser in 1912. Gmelin based his account on the "green warbler" from the East Indies that had been described and illustrated in 1776 by the English naturalist Peter Brown. The ruby-cheeked sunbird is now the only species placed in the genus Chalcoparia that was introduced in 1850 by the German ornithologist Jean Cabanis. The genus name is from Ancient Greek khalkoparēos meaning "with cheeks of bronze". The specific epithet is from the erroneous type locality, Sri Lanka.

Rare
Under 5% of wildlife watchers report a Ruby-cheeked Sunbird sighting in Royal Manas National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 327th most-seen of the 388 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
July
In that month about 10% of wildlife watchers report a Ruby-cheeked Sunbird in Royal Manas National Park on a given day, against under 5% in October to June, the lowest months. That is one of Royal Manas National Park's wettest months, with about 930 mm of rain against 10 mm in December. August and September have too few records to rate.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Ruby-cheeked Sunbird sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
19th of 20
Of the 20 parks where we can rate Ruby-cheeked Sunbird sightings, Royal Manas National Park ranks 19th at under 5%. The best odds are in Sepilok (Malaysia, about 30%), Way Kambas National Park (Indonesia, about 30%) and Kaeng Krachan National Park (Thailand, about 20%).
Same family: Nectariniidae
The closest relatives of the Ruby-cheeked Sunbird that you can see in Royal Manas National Park (family Nectariniidae, Sunbirds and Spiderhunters) are Streaked Spiderhunter (about 60%), Black-throated Sunbird (about 30%) and Crimson Sunbird (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Ruby-cheeked Sunbird is recorded against all the birds logged in Royal Manas National Park (9 verified sightings from 2019 to 2026), 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.
