クロルリノジコ Cyanoloxia cyanoides

Chunky, stout-billed bird of humid evergreen forest and edge in tropical lowlands. Usually found in pairs, often skulking at low to middle levels in lush vegetation. In typical views, looks simply dark. Note the large size relative to buntings, very stout bill, and broad tail, which can be twitched side to side. Male is deep blue-black overall. Female is rich dark brown overall. Sharp squeaky call often doubled and rather distinctive.
