The hook-billed vanga (Vanga curvirostris) is a species of bird in the family Vangidae. It is endemic to Madagascar. Its natural habitats are subtropical or tropical dry forest, subtropical or tropical moist lowland forest, and subtropical or tropical moist montane forest.
In 1760 the French zoologist Mathurin Jacques Brisson included a description of the hook-billed vanga in his Ornithologie based on a specimen collected on the island of Madagascar. He used the French name L'écorcheur de Madagascar and the Latin Collurio Madagascariensis. 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 previously described by Brisson. One of these was the hook-billed vanga. Linnaeus included a brief description, coined the binomial name Lanius curvirostris and cited Brisson's work. It is now the only species placed in the genus Vanga that was introduced by the French ornithologist Louis Pierre Vieillot in 1816.
The genus name Vanga is the Malagasy name for the species. The specific epithet curvirostris is from Latin curvus "curved" and -rostrum "billed". Two subspecies are recognised: A 2018 study on avian skull evolution has concluded that the ancestral neornithe had a beak most similar to this species. This suggests a similar ancestral ecological niche for modern birds. Wikipedia →

Likely
About 50% of wildlife watchers report a Hook-billed Vanga sighting in Berenty Reserve on a given day, based on 100 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 21st most-seen of the 63 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Hook-billed Vanga sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Yes
Of the 4 parks where we can rate Hook-billed Vanga sightings, Berenty Reserve has the highest daily chance: about 50%. Next come Ankarafantsika National Park (Madagascar, about 30%) and Ranomafana National Park (Madagascar, about 20%).
Same family: Vangidae
The closest relatives of the Hook-billed Vanga that you can see in Berenty Reserve (family Vangidae, Vangas, Helmetshrikes, and Allies) are Common Newtonia (about 20%) and Chabert Vanga (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Hook-billed Vanga is recorded against all the birds logged in Berenty Reserve (100 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.
