The thick-billed seed finch (Sporophila funerea) is a species of bird in the family Thraupidae, but was until recently placed in Emberizidae. It is found widely in shrubby and grassy areas from southern Mexico, through Central America, to the Chocó in Colombia and Ecuador. It is replaced by the closely related chestnut-bellied seed finch in South America east of the Andes, as well as the valleys of Cauca and Magdalena in Colombia. The two have often been considered conspecific as the lesser seed-finch (Sporophila angolensis).
The male is almost entirely black, with a small white wing patch. The female is a rich brown all over. They are both very similar to the all-black Caribbean slope form of the variable seedeater. It is distinguished, however, by a larger bill with a straight culmen. They measure 11.5 cm (4.5 in) long and weigh 13.5 g (0.48 oz).

Rare
Under 5% of wildlife watchers report a Thick-billed Seed-Finch sighting in Bastimentos Island National Marine Park on a given day, based on 177 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 181st most-seen of the 375 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
February, April–June and October–November
In those months about 10% of wildlife watchers report a Thick-billed Seed-Finch in Bastimentos Island National Marine Park on a given day, against under 5% in March, July–September and December–January, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Thick-billed Seed-Finch sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
12th of 29
Of the 29 parks where we can rate Thick-billed Seed-Finch sightings, Bastimentos Island National Marine Park ranks 12th at under 5%. The best odds are in Piedras Blancas National Park (Costa Rica, about 20%), San Lorenzo Protected Forest (Panama, about 10%) and Gandoca-Manzanillo Wildlife Refuge (Costa Rica, about 10%).

GBIF citizen-science records
It is estimated from how often the Thick-billed Seed-Finch is recorded against all the birds logged in Bastimentos Island National Marine Park (177 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.
