The name "purple roller" can also refer to the azure dollarbird (Eurystomus azureus) of Indonesia. The purple roller (Coracias naevius), or rufous-crowned roller, is a medium-sized bird widespread in sub-Saharan Africa. Compared with other rollers its colours are rather dull and its voice harsh and grating.
The purple roller was formally described in 1800 by the French zoologist François Marie Daudin under the binomial name Coracias naevia. Daudin's description was based on a specimen collected in Senegal. The specific epithet is from Latin naevius meaning "spotted" or "marked". A molecular phylogenetic study published in 2018 found that the purple roller was most closely related to the racket-tailed roller (Coracias spatulatus).
The phylogenetic relationships among the Coracias species are shown below, from the molecular study by Johansson et al. (2018) Found from Senegal and Gambia to Somalia and northern Tanzania Wikipedia →

Rare
Under 5% of wildlife watchers report a Rufous-crowned Roller sighting in Serrekunda on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 197th most-seen of the 213 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Rufous-crowned Roller in Serrekunda on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Rufous-crowned Roller 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 Serrekunda, in our data
Serrekunda is the only city on Wallace's Line with enough records to rate Rufous-crowned Roller sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Coracias
The closest relatives of the Rufous-crowned Roller that you can see in Serrekunda (genus Coracias, Typical Rollers) are Blue-bellied Roller (about 30%) and Abyssinian Roller (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Rufous-crowned Roller is recorded against all the birds logged in Serrekunda (6 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.
