BirdLife International's Handbook of the Birds of the World (HBW) treats those taxa as full species, the "black-throated" and "black-breasted" brilliants respectively. In addition, for a time in the early 20th century, the two subspecies were treated as species, the only members of genus Ionolaima, which was subsequently merged into the present Heliodoxa. As of May 2022 the SACC has a proposal pending to resurrect Ionolaima but it has gained little support.
The nominate subspecies H. s. schreibersii of black-throated brilliant is 11.5 to 13 cm (4.5 to 5.1 in) long. Males weigh about 9.9 g (0.35 oz) and females 7.1 to 8.5 g (0.25 to 0.30 oz). Both have an almost... Wikipedia →

Rare
Under 5% of wildlife watchers report a Black-throated Brilliant sighting in Yasuní National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 515th most-seen of the 533 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Black-throated Brilliant in Yasuní National Park on a given day, so our monthly data shows no clear season.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Black-throated Brilliant sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 parks where we can rate Black-throated Brilliant sightings, Yasuní National Park ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Podocarpus National Park (Ecuador, under 5%).
GBIF citizen-science records
It is estimated from how often the Black-throated Brilliant is recorded against all the birds logged in Yasuní National Park (7 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.
