Possible
About 20% of wildlife watchers report a White-collared Oliveback sighting in Kigali on a given day, based on 257 verified sightings from GBIF citizen-science data. It is the 58th most-seen of the 244 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.
July, October and December
In those months about 30% of wildlife watchers report a White-collared Oliveback in Kigali on a given day, against about 10% in February and April–May, the lowest months.
Only Kigali, in our data
Kigali is the only city on Wallace's Line with enough records to rate White-collared Oliveback sightings: about 20% of wildlife watchers there report one on a given day.
Same family: Estrildidae
The closest relatives of the White-collared Oliveback that you can see in Kigali (family Estrildidae, Waxbills and Allies) are Bronze Mannikin (about 60%), Red-billed Firefinch (about 30%) and Red-cheeked Cordon-bleu (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the White-collared Oliveback is recorded against all the birds logged in Kigali (257 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.
