Subspecies are somewhat variable in plumage, but they all share several features, such as black sides of head with pale supercilium (white or grey depending on subspecies) again limited above by black; white throat bordered below by a black breast band of very varying width; and yellow at the bend of the wing. The bill is mostly orange, but yellowish in some southern subspecies and mostly dusky in one.


Mexico, through Central America and western South America to Peru. Subspecies spectabilis is isolated on the east side of the Andes while the other South American subspecies are west or north of these mountains.


Eight subspecies are recognized:

  • saturatus
  • rufidorsalis
  • aurantiirostris
  • strictocollaris
  • occidentalis
  • erythrorhynchus
  • spectabilis
  • santarosae


Moist lowland and foothill forest and second-growth.


An elusive bird of the forest floor.
