Van Hasselt's sunbird (Leptocoma brasiliana), is a species of bird in the family Nectariniidae. It is found in Northeast India, Bangladesh and Southeast Asia. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical mangrove forests.
Van Hasselt's sunbird was described and illustrated in 1760 by the French zoologist Mathurin Jacques Brisson. He introduced the French name "Le grimpereau violet de Brésil" in the mistakenly belief that his specimen had been collected in Brazil. When the German naturalist Johann Friedrich Gmelin revised and expanded Carl Linnaeus's Systema Naturae in 1788 he included Van Hasselt's sunbird using Brisson's account. He placed it with the tree-creepers in the genus Certhia and coined the binomial name Certhia brasiliana. He specified the location as Brazil and cited Brisson's book. In 1825 the Dutch zoologist Coenraad Jacob Temminck described and illustrated Van Hasselt's sunbird based on a specimen that had been collected on the island of Java by Johan Conrad van Hasselt. Temminck coined the binomial name Nectarinia hasseltii, choosing the specific epithet to honour the collector. Under the rules of... Wikipedia →

Possible
About 20% of wildlife watchers report a Van Hasselt's Sunbird sighting in Sepilok on a given day, based on 405 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 78th most-seen of the 242 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.
March to June
In those months about 30% of wildlife watchers report a Van Hasselt's Sunbird in Sepilok on a given day, against under 5% in September to November, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Van Hasselt's Sunbird sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 6 parks where we can rate Van Hasselt's Sunbird sightings, Sepilok has the highest daily chance: about 20%. Next come Khao Yai National Park (Thailand, about 10%) and Cat Tien National Park (Vietnam, about 10%).
GBIF citizen-science records
It is estimated from how often the Van Hasselt's Sunbird is recorded against all the birds logged in Sepilok (405 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.
