Rufous motmot
Template:Short description Template:Use American English
The rufous motmot (Baryphthengus martii) is a near-passerine bird in the family Momotidae. It is found from northeastern Honduras south to western Ecuador, northern Bolivia, and western Brazil.[1][2]
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.[2] The rufous motmot has two recognized subspecies, the nominate Baryphthengus martii martii and B. m. semirufus.[1] In the early 20th century, B. m. martii was classified in its own genus, Urospatha.[3] 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.[2] The binomial commemorates the German botanist and explorer Carl Friedrich Philipp von Martius.Script error: No such module "Unsubst".
Description
The rufous motmot is the second-largest member of its family. The male of the nominate subspecies is Script error: No such module "convert". long and weighs Script error: No such module "convert".. The female weighs Script error: No such module "convert".. Male and female B. m. semirufus weigh Script error: No such module "convert". and Script error: No such module "convert". respectively. Adults are mainly cinnamon-rufous, with a black face mask and central breast spot, green wings and sides, a greenish-blue lower belly, and dark blue tail and flight feathers. The tail is very long, and that of B. m. semirufus but not the nominate has a bare-shafted racket tip. The bill and legs are black. Young birds are paler and duller than adults, and lack the tail rackets and black breast spot.[2]
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 Script error: No such module "convert". in Costa Rica and to Script error: No such module "convert". in Panama and Ecuador. In Peru it can be found locally to Script error: No such module "convert". but more generally to Script error: No such module "convert"..[2]
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.[2]
Behavior
Feeding
The rufous motmot is omnivorous. It has been documented eating many types of fruit, adult insects and their larva, arachnids including crustaceans, and small fish, lizards, and frogs.[2]
Breeding
The rufous motmot's breeding and nesting phenology has few reported details. It is assumed to nest in deep burrows in earthen banks like other motmots. The clutch size and eggs are undescribed.[2]
Vocalization
The rufous motmot's song has been described as "hoos, hoots, or hoops".[4] It is sometimes answered by a low owl-like hoop hoop huhuhuhuhuhu.[5] An agitation call is a dry chatter.[6][2]
Status
The IUCN has assessed the rufous motmot as being of Least Concern.[7]
