Kara Gagalı Koca Tohumcul Sporophila atrirostris

Rare seed-eating bird found in wet, grassy areas (often near water) in lowlands and foothills east of the Andes. Note the very stout, dark bill. Male is black with a small white patch in the wing that may be concealed when perched. Brown female is not easily identified unless seen together with the male. She is smaller than female Chestnut-bellied Seed-Finch, and tends to be slightly darker than female Large-billed Seed-Finch.
