The specific epithet gularis is Modern Latin meaning "-throated". Vieillot based his description on a specimen in the Muséum National d'Histoire Naturelle in Paris which he mistaken believed had been collected in "Australasie"; the type locality has been designated as Senegal. A molecular phylogenetic study published in 2018 found that the blue-throated roller was most closely related to the broad-billed roller (Eurystomus glaucurus).

With luck
About 10% of wildlife watchers report a Blue-throated Roller sighting in Bwindi Impenetrable National Park on a given day, based on 120 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 178th most-seen of the 400 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
April–July and November–December
In those months about 10% of wildlife watchers report a Blue-throated Roller in Bwindi Impenetrable National Park on a given day, against under 5% in January–March and August–October, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Blue-throated Roller sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 5
Of the 5 parks where we can rate Blue-throated Roller sightings, Bwindi Impenetrable National Park ranks 3rd at about 10%. The best odds are in Semuliki National Park (Uganda, about 30%) and Taï National Park (Ivory Coast, about 10%).
GBIF citizen-science records
It is estimated from how often the Blue-throated Roller is recorded against all the birds logged in Bwindi Impenetrable National Park (120 verified sightings from 2019 to 2026), 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.
