Rare
Under 5% of wildlife watchers report a Greater Swamp Warbler sighting in Abuja on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 108th most-seen of the 131 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
April and November–January
In those months about 10% of wildlife watchers report a Greater Swamp Warbler in Abuja on a given day, against under 5% in February–March and May–October, the lowest months. Those are among Abuja's driest months, with about 25 mm of rain a month against 250 mm in August.
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.
3rd of 5
Of the 5 cities where we can rate Greater Swamp Warbler sightings, Abuja ranks 3rd at under 5%. The best odds are in Dakar (Senegal, about 10%) and Accra (Ghana, about 10%).
GBIF citizen-science records
It is estimated from how often the Greater Swamp Warbler is recorded against all the birds logged in Abuja (10 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.
