Possible
About 20% of wildlife watchers report a Madagascar Swamp Warbler sighting in Antananarivo on a given day, based on 193 verified sightings from GBIF citizen-science data. It is the 31st most-seen of the 69 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.
January and September–October
In those months about 30% of wildlife watchers report a Madagascar Swamp Warbler in Antananarivo on a given day, against about 10% in June and August, the lowest months.
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.
Only Antananarivo, in our data
Antananarivo is the only city on Wallace's Line with enough records to rate Madagascar Swamp Warbler sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Madagascar Swamp Warbler is recorded against all the birds logged in Antananarivo (193 verified sightings), 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.
