The Rufous Motmots (Baryphthengus martii) - also known as Martin's Rufous Motmots - are colorful birds found in Central and South America, where they inhabit tall humid lowland and hill forests and second growth. These largest of all motmot species are relatively common within their range.

Distribution / Habitat

Rufous Motmots occur naturally in the rain forests from northeastern Honduras in Central America south to western Ecuador, northeastern Bolivia, and southwestern Brazil in South America. They are resident (non-migatory).

They are typically associated with lowland evergreen forest areas:

  • Costa Rica: up to about 4,100 feet (~ 1,250 meters)
  • Southern Panama and Ecuador: up to about 4,600 feet (~ 1,400 meters)
  • Peru: up to about 4,300 feet (~ 1,300 meters), locally as high as 5,200 feet (~1,600 meters)

They typically remain close to bodies of water, and are often seen in pairs.

Subspecies and Ranges:

Rufous Motmot (nominate race) (Baryphthengus martii martii - Spix, 1824) - Southern Form

Range: From southeastern Colombia south to northern Bolivia and east to the Rio Tapajos in Brazil.

Rufous Motmot (ssp. semirufus) (Baryphthengus martii semirufus - Sclater,PL, 1853) - Northern Form

Range: Eastern Honduras, Eastern Nicaragua, Caribbean slopes of Costa Rica and Panama, northwestern Colombia (to the eastern bank of the Magdalena river in Boyacá) and western Ecuador west of the Andes mountain range.

[Rufous Motmot (ssp. costaricensis) (Baryphthengus martii semirufus [costaricensis] - Todd, 1943] - The Costa Rican and Nicaraguan form is not universally recognized as a subspecies in spite of their larger size and some minor differences in coloration. They are typically lumped together with ssp. semirufus

  • Animal foods, such as larval and adult insects (including beetles, crickets, grasshoppers, katydids, roaches and wasps), arachnids (including spiders, scorpions and whip scorpions), lizards, fish, crabs and frogs. Animal prey is beaten on a branch or other substrate before consuming.
  • Fruits and vegetation: Fruits of Heliconias, nutmegs (Virola), palms, berries, as well as seeds of Inga and Protium.

Breeding / Nesting

The breeding season varies by location, but most breeding activities have been observed between March and June.

They nest in 10 to 16 ft (3 - 5 meter) long burrows that both parents dig and/or refurbish (abandoned mammal burrows).
