It has been introduced in many other parts of the world and has established itself in Argentina, Tonga and Fiji, as well as parts of Samoa, USA and Cook Islands. It is included in the list of the world's 100 worst invasive alien species. In New Zealand they were the target of a successful extermination campaign in 1955, however they are still sporadically reported.
In 1760 the French zoologist Mathurin Jacques Brisson included a description of the red-vented bulbul in his Ornithologie based on a specimen that he mistakenly believed had been collected from the Cape of Good Hope in South Africa. He used the French name Le merle hupé du Cap de Bonne Espérance and the Latin Merula Cristata Capitis Bonae Spei. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added 240 species that had been...

Very likely
About 80% of wildlife watchers report a Red-vented Bulbul sighting in Gir National Park on a given day, based on 179 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 2nd most-seen of the 139 birds we can rate there. Over three days the chance rises to over 90%, if each day is a fresh chance.
February and March
In those months about 90% of wildlife watchers report a Red-vented Bulbul in Gir National Park on a given day, against about 60% in September, the lowest month. Those are among Gir National Park's driest months, with almost no rain against 330 mm in July. July and August have too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Red-vented Bulbul sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 26 parks where we can rate Red-vented Bulbul sightings, Gir National Park ranks 5th at about 80%, level with the leaders once rounded. The best odds are in Udawalawe National Park (Sri Lanka, about 80%), Ranthambore National Park (India, about 80%) and Yala National Park (Sri Lanka, about 80%). All parks ranked.
Same order: Passeriformes
The closest relatives of the Red-vented Bulbul that you can see in Gir National Park (order Passeriformes, Perching Birds) are Oriental Magpie-Robin (about 70%), Large-billed Crow (about 70%) and Indian Robin (about 70%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Red-vented Bulbul is recorded against all the birds logged in Gir National Park (179 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.
