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 Sian Ka'an Biosphere Reserve on a given day, based on 19 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 239th most-seen of the 288 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
October
In that month about 10% of wildlife watchers report a Blue-black Grassquit in Sian Ka'an Biosphere Reserve on a given day, against under 5% in November to September, the lowest months. That is one of Sian Ka'an Biosphere Reserve's wettest months, with about 160 mm of rain against 30 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.
69th of 73
Of the 73 parks where we can rate Blue-black Grassquit sightings, Sian Ka'an Biosphere Reserve ranks 69th at under 5%. The best odds are in Emas National Park (Brazil, about 70%), Serra da Canastra National Park (Brazil, about 50%) and Cerro Azul Meámbar National Park (Honduras, about 30%). All parks ranked.

GBIF citizen-science records
It is estimated from how often the Blue-black Grassquit is recorded against all the birds logged in Sian Ka'an Biosphere Reserve (19 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.
