This species was formerly placed in the genus Amazilia. A molecular phylogenetic study published in 2014 found that Amazilia was polyphyletic. In the revised classification to create monophyletic genera, the glittering-throated emerald and the sapphire-spangled emerald (Chionomesa lactea) were moved by most taxonomic systems to the resurrected genus Chionomesa that had...

Rare
Under 5% of wildlife watchers report a Glittering-throated Emerald sighting in São Paulo on a given day, based on 26 verified sightings from GBIF citizen-science data. It is the 269th most-seen of the 353 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 Glittering-throated Emerald in São Paulo on a given day, so our monthly data shows no clear season.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Glittering-throated Emerald sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Glittering-throated Emerald is recorded against all the birds logged in São Paulo (26 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.
