The black-faced grassquit (Melanospiza bicolor) is a small bird in the family Thraupidae, the tanagers and allies. It is found in the West Indies except Cuba Colombia, Venezuela and islands off its coast, and on islands in the western Caribbean Sea.
The first formal description of the black-faced grassquit was by the Swedish naturalist Carl Linnaeus in 1766 in the twelfth edition of his Systema Naturae. He introduced the binomial name Fringilla bicolor. Linnaeus based his description on the "Bahama Sparrow" that was described and illustrated by Mark Catesby in his The Natural History of Carolina, Florida and the Bahama Islands which was published between 1729 and 1732. By 1970 it had been reassigned to the genus Tiaris. A molecular phylogenetic study published in 2014 found that this genus was polyphyletic and that the black-faced grassquit was closely related to the Saint Lucia black finch in the (then) monospecific genus Melanospiza. In the resulting reorganization of the genera, between 2016 and 2020 taxonomic systems moved the black-faced grassquit to Melanospiza.

Possible
About 30% of wildlife watchers report a Black-faced Grassquit sighting in Maracaibo on a given day, based on 198 verified sightings from GBIF citizen-science data. It is the 18th most-seen of the 89 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
April
In that month about 50% of wildlife watchers report a Black-faced Grassquit in Maracaibo on a given day, against about 20% in January and September–October, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Black-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.
2nd of 3
Of the 3 cities where we can rate Black-faced Grassquit sightings, Maracaibo ranks 2nd at about 30%. The best odds are in Caracas (Venezuela, about 50%).
Same family: Thraupidae
The closest relatives of the Black-faced Grassquit that you can see in Maracaibo (family Thraupidae, Tanagers and Allies) are Blue-gray Tanager (about 70%), Bananaquit (about 40%) and Olivaceous Saltator (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black-faced Grassquit is recorded against all the birds logged in Maracaibo (198 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.
