With luck
About 10% of wildlife watchers report a Madagascar Swift sighting in Antananarivo on a given day, based on 155 verified sightings from GBIF citizen-science data. It is the 37th most-seen of the 69 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
January and October–November
In those months about 20% of wildlife watchers report a Madagascar Swift in Antananarivo on a given day, against under 5% in May, the lowest month.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Madagascar Swift 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.
Only Antananarivo, in our data
Antananarivo is the only city on Wallace's Line with enough records to rate Madagascar Swift sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Madagascar Swift is recorded against all the birds logged in Antananarivo (155 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.
