Taxonomy and systematics

The rufous motmot and rufous-capped motmot (''Baryphtengus ruficapillus'') are the only two species in their genus, and have sometimes been treated as conspecific and apparently form a superspecies. The rufous motmot has two recognized subspecies, the nominate '' Baryphthengus martii martii'' and ''B. m. semirufus''. In the early 20th century, ''B. m. martii'' was classified in its own genus, ''Urospatha''.Remsen, J. V., Jr., J. I. Areta, E. Bonaccorso, S. Claramunt, A. Jaramillo, D. F. Lane, J. F. Pacheco, M. B. Robbins, F. G. Stiles, and K. J. Zimmer. Version 19 January 2021. A classification of the bird species of South America. American Ornithological Society. https://www.museum.lsu.edu/~Remsen/SACCBaseline.htm retrieved January 19, 2021 Later, the Nicaraguan and Costa Rican populations were considered to be a third subspecies, ''B. m. costaricensis'', but it was decided they were part of ''B. m. semirufus''. The binomial commemorates the German botanist and explorer Carl Friedrich Philipp von Martius.

Young birds are paler and duller than adults, and lack the tail rackets and black breast spot.

Distribution and habitat

The nominate subspecies of rufous motmot occurs in the western Amazon Basin in southeastern Colombia through eastern Ecuador and Peru to northern Bolivia, and east into western Brazil. The range of ''B. m. semirufus'' is separate from that of the nominate. It occurs from eastern Honduras through the Caribbean slopes of Nicaragua, Costa Rica, and Panama, and continues on the Pacific slope of Panama into northwestern Colombia and western Ecuador. In elevation it ranges from near sea level to in Costa Rica and to in Panama and Ecuador. In Peru it can be found locally to but more generally to .

The rufous motmot inhabits humid lowland evergreen primary forest and also secondary forest. It prefers tall forest, especially along rivers and streams, but avoids dense foliage.
