Bare-Throated Bellbird

One of the loudest birds in the world is the male Bare-Throated Bellbird. Argentina, Brazil, and Paraguay all have moist subtropical and tropical forests where they can be found. The male has bristly bluish-black exposed skin around its eye, beak, and throat, and white plumage. The female is more uninspiring; she has olive-brown upperparts and yellow underparts with streaking. The male produces one of the loudest bird calls ever recorded, which sounds metallic and reminiscent of a hammer hitting an anvil. This bird consumes fruit and assists in spreading forest tree seeds.

Although this behavior tends to vary among populations, this species appears to migrate in at least some areas, including southeast Brazil. The International Union for Conservation of Nature (IUCN) has listed the Bare-throated Bellbird as Vulnerable to extinction due to habitat degradation and the pet bird trade.
