Rare
Under 5% of wildlife watchers report a Pollen's Vanga sighting in Mantadia National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 87th most-seen of the 98 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
October
In that month about 10% of wildlife watchers report a Pollen's Vanga in Mantadia National Park on a given day, against under 5% in May–September and November–December, the lowest months. That is one of Mantadia National Park's driest months, with about 70 mm of rain against 340 mm in January. January to April have too few records to rate.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Pollen's Vanga sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 parks where we can rate Pollen's Vanga sightings, Mantadia National Park ranks 2nd at under 5%. The best odds are in Ranomafana National Park (Madagascar, about 40%).
Same family: Vangidae
The closest relatives of the Pollen's Vanga that you can see in Mantadia National Park (family Vangidae, Vangas, Helmetshrikes, and Allies) are Red-tailed Vanga (about 50%), Common Newtonia (about 50%) and Nuthatch-Vanga (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Pollen's Vanga is recorded against all the birds logged in Mantadia National Park (8 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.
