Rand's warbler (Randia pseudozosterops) is a species in the family Bernieridae. It is found only in Madagascar, where it is restricted to the island's eastern rainforests. It is grey above and unmarked pale below, with a strong pale supercilium. The bill is strong and slightly decurved, with some individuals possessing a pale orange lower mandible.
Its natural habitat is subtropical or tropical moist lowland forests, where it is fairly common up to 1200 m. It frequently joins mixed-species flocks, where it often feeds along horizontal or angled branches. It also tends to sing for long periods from the canopy. While not considered threatened, its population is inferred to be decreasing due to widespread deforestation across its range.
A 2019 phylogenetic study found Rand's warbler to be the sister species of the Thamnornis. Wikipedia →

Likely
About 40% of wildlife watchers report a Rand's Warbler sighting in Ranomafana National Park on a given day, based on 324 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 25th most-seen of the 102 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.
September and November
In those months about 50% of wildlife watchers report a Rand's Warbler in Ranomafana National Park on a given day, against about 20% in April–May and July–August, the lowest months. January and June have too few records to rate.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Rand's Warbler sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
2nd of 2
Of the 2 parks where we can rate Rand's Warbler sightings, Ranomafana National Park ranks 2nd at about 40%. The best odds are in Mantadia National Park (Madagascar, about 50%).
Same family: Bernieridae
The closest relatives of the Rand's Warbler that you can see in Ranomafana National Park (family Bernieridae, Malagasy Warblers) are Spectacled Tetraka (about 40%), Long-billed Bernieria (about 40%) and White-throated Oxylabes (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Rand's Warbler is recorded against all the birds logged in Ranomafana National Park (324 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.
