Van Dam's vanga (Xenopirostris damii) is a species of bird in the family Vangidae. It is endemic to Madagascar. Its natural habitat is subtropical or tropical dry forests. Males may be identified by their black hood whereas females have only a black cap.
At present, the species is endangered under the ICUN Species Red List. It has a decreasing population trend of between 1500 and 7000 individuals. The species inhabits a very small range, isolated to just two confirmed sites, one of which is the Ankarafantsika National Park. Its habitat is under increasing pressure from human encroachment and fire.

Likely
About 40% of wildlife watchers report a Van Dam's Vanga sighting in Ankarafantsika National Park on a given day, based on 200 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 31st most-seen of the 83 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
July and October–December
In those months about 50% of wildlife watchers report a Van Dam's Vanga in Ankarafantsika National Park on a given day, against about 30% in April and August–September, the lowest months. January–March and May have too few records to rate.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Van Dam's 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.
Only Ankarafantsika National Park, in our data
Ankarafantsika National Park is the only park on Wallace's Line with enough records to rate Van Dam's Vanga sightings: about 40% of wildlife watchers there report one on a given day.
Same family: Vangidae
The closest relatives of the Van Dam's Vanga that you can see in Ankarafantsika National Park (family Vangidae, Vangas, Helmetshrikes, and Allies) are Common Newtonia (about 80%), Rufous Vanga (about 60%) and Sickle-billed Vanga (about 50%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Van Dam's Vanga is recorded against all the birds logged in Ankarafantsika National Park (200 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.
