The blue-black grassquit (Volatinia jacarina) is a small Neotropical bird in the family Thraupidae, the tanagers and allies. It is found in Mexico, every Central American country, every mainland South American country, in Trinidad and Tobago, and in Grenada.

Rare
Under 5% of wildlife watchers report a Blue-black Grassquit sighting in Caracas on a given day, based on 401 verified sightings from GBIF citizen-science data. It is the 106th most-seen of the 295 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
June–August and October
In those months about 10% of wildlife watchers report a Blue-black Grassquit in Caracas on a given day, against under 5% in September and November–May, the lowest months. Those are among Caracas's wettest months, with about 100 mm of rain a month against 15 mm in March.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Blue-black 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.
22nd of 35
Of the 35 cities where we can rate Blue-black Grassquit sightings, Caracas ranks 22nd at under 5%. The best odds are in San Pedro Sula (Honduras, about 30%), Lima (Peru, about 30%) and Goiânia (Brazil, about 30%).
Same family: Thraupidae
The closest relatives of the Blue-black Grassquit that you can see in Caracas (family Thraupidae, Tanagers and Allies) are Blue-gray Tanager (about 90%), Saffron Finch (about 60%) and Bananaquit (about 60%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Blue-black Grassquit is recorded against all the birds logged in Caracas (401 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.
