Slate-colored Grosbeak

A large, heavy-billed seed-eating bird of humid lowland forest in the Amazon basin, Central America, and northern South America, slate-colored grosbeaks have uniform dark slate-grey plumage with a powerful, pale bill. Despite their name, they are placed in the saltator genus. They inhabit dense, humid forest interior and forest edge, foraging in pairs or small groups on large seeds and hard fruits. Their powerful bills crack seeds too tough for most other birds. Listed as Least Concern.
