The male Chestnut-Bellied Seed-Finch has a large bill, chestnut belly, and is otherwise black with a white mark on wing. All the individuals I saw in eastern Ecuador were similar to the bird pictured above, with a mottled aspect to the chestnut underparts.

The female is brown. The photo below is probably one, based on bill shape.

The Chestnut-Bellied Seed-Finch used to be grouped with the Thick-billed Seed-finch as the Lesser Seed-Finch.
