It is considerably smaller than White-necked Puffbird.

Among black and white Puffbirds, this one is unique in having buffy belly and grey flank barring.


Atlantic forest in south-eastern Brazil, eastern Paraguay, and north-eastern Argentina.


This is a monotypic species1.

Some authorities have treated this as a subspecies of White-necked Puffbird.


Atlantic Rain Forest.



"The song of swainsoni begins with a long series of 15+ "ui-ui-ui-ui" notes, which accelerate in pace and build in intensity before switching to a nearly as long series of 10+ disyllabic or trisyllabic "dibule-dibule-dibule" notes that descend in pitch but still accelerate toward the finish."2
