Although its extent of occurrence is probably less than 10,000 km2, this species is listed as Least Concern in view of its presumed large and stable population, occurrence in a number of protected areas, and because it does not appear to be under threat and is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.

Habitat and Ecology [top]

Habitat and Ecology:This species is found in grasslands in high elevation in Panama and Costa Rica (Blondel et al. 2009).

This species favours cold environments (Reid 1997). It is terrestrial, travelling in runways under logs and among rocks or through dense vegetation. Almost entirely insectivorous in diet, it prefers larval beetles, which are probably located by smell. Little nest-building activity occurs in captivity, and nests have not been found in the wild. It appears to breed year-round; litters size is 2 to 4 young, averaging 2.7 (Reid 1997).
Generation Length (years):1-2

Threats [top]

Major Threat(s): There are no major threats to this species, though in parts of its range it is adversely affected by agrochemicals, loss of grassland habitat (to development) and to some extent, deforestation.

Conservation Actions [top]

Conservation Actions: Much of its habitat occurs within protected areas.
