The White-necked Puffbird (Notharchus hyperrhynchus) is a species of puffbird in the Bucconidae family. It is found in forest and woodland from southern Mexico, through Central America, to the Chocó, northern Colombia (including Magdalena Valley), northern Venezuela, and the western and southern Amazon Basin. It was formerly considered a subspecies of N. macrorhynchos, but under the common name White-necked Puffbird. The two differ markedly in bill-size (N. hyperrhynchus larger-billed than N. macrorhynchos), plumage (among others, N. hyperrhynchus has less black to the flanks and more white to the forecrown than N. macrorhynchos), and voice. Consequently, the two were separated by SACC in 2004.
