The Amazonian motmot's plumage varies among the subspecies. The bodies of all are shades of green. All have a long tail that has extended feathers with racquet tips that are green or black. Most have a black eyemask, though their size and shape differ. The central crown is black and surrounded or partially bordered by a blue band. The nominate subspecies has a chestnut nape. Momotus momota ignobilis and M. m. cametensis have more extensive chestnut on the neck and face.

  • M. m. nattereri — northeastern Bolivia
  • M. m. simplex — western to west central Brazil south of the Amazon
  • M. m. cametensis — north central Brazil
  • M. m. parensis — northeastern Brazil
  • M. m. marcgravianus — eastern Brazil
  • M. m. pilcomajensis — southern Bolivia, southern Brazil, and northwestern Argentina
Throughout its range the Amazonian motmot inhabits the interior and edges of humid lowland forest. It is found up to in Venezuela, to in Ecuador, and to in Peru.

Behavior

Feeding

The Amazonian motmot is omnivorous. It has been documented eating insects and other arthropods, small mammals and reptiles, and fruit.

Breeding

Like most Coraciiformes, the Amazonian motmot nests in long tunnels in earth banks. Very little else is known about its breeding phenology.

Vocalization

The Amazonian motmot's song has been described as "a fast, hollow hoo-do" and "a bubbling whOOP-oo". It also makes "a gruff kak", sometimes in a series.
