This species is listed as Least Concern in because of its wide distribution, presumed large population, occurrence in a number of protected areas, tolerance to some degree of habitat modification, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.

Geographic Range [top]

Range Description:This species is found from Tamaulipas, northeastern Mexico including the Yucatan Peninsula, in many lowland tropical forest (typically below 1,000 m) of Central and South America. There are at least two disjunct populations, one in Central America, Mexico, and into South America (western Colombia and western Ecuador), and another population living in western Perú, most of Boliva western Brazil, central Paraguay along the banks of the Rio Paraguay, and south into northern Argentina (Patton and da Silva 2008, de la Sancha and D’Elía 2015). There are four recognized subspecies, and this is probably a species complex that could be divided into various species in the near future (see Patton and da Silva 2008 for details). Descriptions on its current distribution reflects that of the four subspecies.

Habitat and Ecology [top]

Habitat and Ecology:This species is found in throughout a variety of habitats which include humid forests, primary and secondary growth forests, gallery forests, and along watercourses. It is most commonly found in moist/humid areas, but it also occurs in nearly all vegetation types, including deciduous and evergreen forests, and drier habitats such as Chacoan forests (Astúa 2015). This species is nocturnal, arboreal and terrestrial, with good swimming abilities. The species is highly omnivorous, feeding on different plant and animal material, including vertebrates and invertebrates, and a whole variety of fruits (Astúa 2015).

Threats [top]

Major Threat(s): No major threats are known to this species.

Conservation Actions [top]

Conservation Actions: More research is needed on methods to provide more habitat protection, and surveys to establish its range of occurrence and abundance. This species occurs in many protected areas throughout its range.
