Possible
About 20% of wildlife watchers report a Madagascar Swamp Warbler sighting in Mantadia National Park on a given day, based on 122 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 54th most-seen of the 98 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
September
In that month about 40% of wildlife watchers report a Madagascar Swamp Warbler in Mantadia National Park on a given day, against about 20% in May–August and October–December, the lowest months. That is one of Mantadia National Park's driest months, with about 60 mm of rain against 340 mm in January. January to April have too few records to rate.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Madagascar Swamp Warbler sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 parks where we can rate Madagascar Swamp Warbler sightings, Mantadia National Park has the highest daily chance: about 20%. Next come Ranomafana National Park (Madagascar, about 10%).
GBIF citizen-science records
It is estimated from how often the Madagascar Swamp Warbler is recorded against all the birds logged in Mantadia National Park (122 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.
