The bare-throated bellbird (Procnias nudicollis) is a species of bird in the family Cotingidae. It is found in moist subtropical and tropical forests in Argentina, Brazil, and Paraguay. The male has white plumage and bristly bluish-black bare skin around its eye, beak and throat. The female is more drab, being olive-brown above with streaked yellow underparts. The male has one of the loudest bird calls known, producing a metallic sound similar to a hammer striking an anvil. This bird feeds on fruit and plays a part in dispersing the seeds of forest trees. It is considered a vulnerable species because of loss of its forest habitat and collection for the pet bird trade.
