Rare
Under 5% of wildlife watchers report a Greater Swamp Warbler sighting in Kigali on a given day, based on 34 verified sightings from GBIF citizen-science data. It is the 148th most-seen of the 244 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
January and August–September
In those months about 10% of wildlife watchers report a Greater Swamp Warbler in Kigali on a given day, against under 5% in February–July and October–December, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Greater 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.
4th of 5
Of the 5 cities where we can rate Greater Swamp Warbler sightings, Kigali ranks 4th at under 5%. The best odds are in Dakar (Senegal, about 10%), Accra (Ghana, about 10%) and Abuja (Nigeria, under 5%).
Same genus: Acrocephalus
The closest relatives of the Greater Swamp Warbler that you can see in Kigali (genus Acrocephalus, Reed Warblers) are Lesser Swamp Warbler (about 10%) and Eurasian Reed-Warbler (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Greater Swamp Warbler is recorded against all the birds logged in Kigali (34 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.
