Cuvier's Toucan (Ramphastos cuvieri) was once considered a subspecies of the Red Bill Toucan (R. tucanus) but achieved full species status in the 1990s following the work of Sibley & Monroe. Cuvier's Toucans occur south of Venezuela south to central and western Brazil into eastern and northern Peru. They can easily be confused in the field with the Yellow Ridged Toucan (Ramphastos vitellinus culminatus). Both birds are so close in size and appearance that only their calls readily distinguish them. The Cuvier has a yelping call similar to a Red Bill or Swainson, whereas the Yellow Ridged has a croaking call similar to the Channel Bill, of which it is a subspecies. Cuvier's Toucans were common in the U.S. in the 1960s and early 1970s but have since gradually disappeared, perhaps because they were never bred in captivity. The only Cuvier's in captivity today are at the Dallas World Aquarium. They are not listed on CITES.
