The Key to Scientific Names
Legend Overview
Introduction
An Atlantic Forest endemic, which is found from southeast Brazil to eastern Paraguay and extreme northeast Argentina, the Buff-bellied Puffbird was formerly considered conspecific with the White-necked Puffbird (Notharchus hyperrhynchus) and the Guianan Puffbird (Notharchus macrorhynchos). The present species is easily distinguished from either of the latter two species by its pale buffy-rufous ventral region, below the black breast band, vocalizations, and also its different oestology. This puffbird is generally found in lowland forest regions, but it regularly ventures into clearings and other disturbed areas, and like others of its genus the species still-hunts insects and small vertebrates from a high perch. Although the Buff-bellied Puffbird is not considered globally threatened, it is generally rather uncommon over much of its range, except perhaps in eastern Paraguay.
Field Identification
23·5 cm; 72–75·6 g (1). Black upperparts glossed green, feathers buffy-edged; very narrow white forehead , white throat and upper breast , greyish-white sides of face and thin nape-collar; black breastband, pale rufous abdomen , grey patches on sides ; bill black; iris red, brown or straw-coloured; feet black. Differs from very similar N. macrorhynchos mainly in green gloss above, pale rufous belly with much more limited, greyer flank marks, greyer face and hindcollar, narrower black breastband, smaller bill. Immature duller; pectoral band may be incomplete; iris brown.

Conservation Status
Not globally threatened. In Brazil, range recently shown to be wider than thought, in S reaching W to Mato Grosso do Sul, and in N now known from S Bahia (3); relatively rare in São Paulo state, uncommon in Paraná, where range recently extended and has been found in several protected areas (4); frequently encountered in E Paraguay; generally rare in Argentina (Misiones), though regularly recorded in Iguazú area.
