Neotropical bellbird

Neotropical bellbird (or simply bellbird) is the common name given to passerine birds of the genus Procnias, found in the Neotropics. They are members of the cotinga family. They are all restricted to tropical or subtropical humid forested regions, often in low mountains or foothills. As indicated by their common name, they all have extremely loud calls that are reminiscent of a metal bell being rung.

Three of the four species are restricted to South America, while the last, the three-wattled bellbird, is restricted to southern Central America.

They are strongly sexually dimorphic. Males have an at least partially white plumage, and facial wattles or bare facial skin. Females lack the wattles/bare facial skin, and are overall olive with yellowish streaks below.
