Taxonomy. Sciurus richmondi Nelson, 1898 View in CoL ,

“Escondido River, Nicaragua.”

Restricted by E. W. Nelson in 1899 to “Escondido River (50 miles [80 km] above Blufiekds), Nicaragua.”

This species is monotypic.

Distribution. Nicaragua.

Descriptive notes. Head-body 160-218 mm, tail 130-184 mm; weight 235-268 g. Dorsum of Richmond’s Squirrelis nearly uniform dark brown, washed with ocherous tones. Venteris yellow-buff to or- ange. Tail is same color as dorsum above and tawny ocherous below.

Habitat. [Lowland mature primary and gal- lery forests, often in riparian areas. While most common in primary forest, Rich- mond’s Squirrel can persist in agricultural plantations and second-growth forests.

Food and Feeding. Richmond’s Squirrel forages on the ground, lower branches, and tree trunks but rarely in the canopy. It is herbivorous and feeds on seeds, nuts, fruits, and other plant tissues.

Breeding. Breeding season of Richmond’s Squirrel occur in February-September, after which litters of 2-3 young are produced in leaf nests or cavities.

Activity patterns. Richmond’s Squirrels are diurnal and active throughout the year, starting activity in early morning.

Movements, Home range and Social organization. Richmond’s Squirrel appears to live and forage alone, only occasionally interacting with others while foraging on the ground and in lower canopy levels.

Status and Conservation. Classified as Near Threatened on The IUCN Red List. Population trend of Richmond’s Squirrel is unknown. Lack of information on ecology, natural history, or threats likely impedes conservation and management efforts. It is likely vulnerable to deforestation in its extremely limited distribution. Despiteits small size, Richmond’s Squirrel is occasionally harvested. Richmond’s Squirrel likely faces considerable conservation challenges because of its small distribution and loss and fragmentation of its habitat.
