Yellow-throated Squirrel
Sciurus gilvigularis View in CoL
French: Ecureuil du Brésil / German: Gelbkehlhérnchen / Spanish: Ardilla de garganta amarilla
Taxonomy. Sciurus gilvigularis Wagner, 1842 View in CoL ,
“Brazil, Borba, Rio Madeira.”
Two subspecies are recognized.
Subspecies and Distribution.
S. g. gilvigularis Wagner, 1842 — N Brazil, S Venezuela, and NE Guyana; however the range is disjunct and poorly known.
S. g. paraensis Goeldi & Hagmann, 1904 —
S range in Brazil is unclear but likely S of
Amazon River.
Descriptive notes. Head-body 155-177 mm, tail 1656-195 mm; weight 150-165 g. The Yellow-throated Squirrel has short thin pelage, with grizzled dorsum of ocherous buff and black and a pale buff eye ring. Ventral pelage is dark ocherous orange, palest on throat and lower abdomen. Tail is sometimes faintly banded and grizzled with buff and black, washed with fulvous or white, and edged in buff. Nominate gilvigularis has tail washed in fulvous, whereas paraensis is washed with white.
Habitat. Humid coastal and evergreen forests dominated by palms, lianas, and rattans. Yellow-throated Squirrels appear to be absent from secondary or logged forests.
Food and Feeding. The Yellow-throated Squirrel is herbivorous and feeds primarily on seeds and fruit of palms. Maripa palm (Attalea maripa, Arecaceae) and its large fruits are favored, but various small tree seeds are also consumed. Yellow-throated Squirrels sit on branches or rattans near palms to feed, and loud gnawing of seed hulls betray their locations.
Breeding. There is no information available for this species.
Activity patterns. Yellow-throated Squirrels are diurnal and active throughout the year.
Movements, Home range and Social organization. The Yellow-throated Squirrel appears to be solitary and lives at low densities.
Status and Conservation. Classified as Data Deficient on The IUCN Red List. Population trend of the Yellow-throated Squirrel is unknown. Lack of information on ecology, natural history, or threats likely impedes conservation and management efforts; it might be vulnerable to deforestation.
