About 20% of wildlife watchers report a Madagascar Yellowbrow sighting in Ranomafana National Park on a given day, based on 132 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 55th most-seen of the 102 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 80%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Madagascar Yellowbrow is recorded against all the birds logged in Ranomafana National Park (132 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.
