He used the French name Le bruant de S. Domingue and the Latin name Emberiza dominicensis.

When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition he added 240 species that had been previously described by Brisson. One of these was the yellow-faced grassquit. Linnaeus included a terse description, coined the binomial name Emberiza olivacea and cited Brisson's work. The specific name olivaceus is Neo-Latin for "olive-green". This is now the only species placed in the genus Tiaris that was introduced by the English naturalist William Swainson in 1827.

Rare
Under 5% of wildlife watchers report a Yellow-faced Grassquit sighting in Panama City on a given day, based on 117 verified sightings from GBIF citizen-science data. It is the 162nd most-seen of the 363 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
November
In that month about 10% of wildlife watchers report a Yellow-faced Grassquit in Panama City on a given day, against under 5% in December to October, the lowest months. That is one of Panama City's wettest months, with about 250 mm of rain against 10 mm in February.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Yellow-faced Grassquit sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
7th of 7
Of the 7 cities where we can rate Yellow-faced Grassquit sightings, Panama City ranks 7th at under 5%. The best odds are in Santo Domingo (Dominican Republic, about 30%), Medellín (Colombia, about 20%) and Havana (Cuba, about 10%).
Same family: Thraupidae
The closest relatives of the Yellow-faced Grassquit that you can see in Panama City (family Thraupidae, Tanagers and Allies) are Blue-gray Tanager (about 60%), Palm Tanager (about 40%) and Crimson-backed Tanager (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Yellow-faced Grassquit is recorded against all the birds logged in Panama City (117 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.
