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 →

Rare
Under 5% of wildlife watchers report a Van Hasselt's Sunbird sighting in Kuala Lumpur on a given day, based on 23 verified sightings from GBIF citizen-science data. It is the 168th most-seen of the 228 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Van Hasselt's Sunbird in Kuala Lumpur on a given day, so our monthly data shows no clear season.
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 2 cities where we can rate Van Hasselt's Sunbird sightings, Kuala Lumpur has the highest daily chance: under 5%. Next come Singapore (Singapore, under 5%).
GBIF citizen-science records
It is estimated from how often the Van Hasselt's Sunbird is recorded against all the birds logged in Kuala Lumpur (23 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.
