The wedge-billed woodcreeper (Glyphorynchus spirurus) is a passerine bird which breeds in the tropical New World from southern Mexico to northern Bolivia, central Brazil and the Guianas. The short wedge-shaped bill of Glyphorynchus spirurus is quite different in shape from that of other woodcreepers.
