Way of life

Very few data and observations are available about Sanborn's squirrel; it is known only from a few collected individuals. It lives in a limited area in the Amazon rainforest at altitudes of 300 to 580 meters. The animals are diurnal and their way of life probably corresponds to other tree-living squirrels of their size.

Systematics

Sanborn's squirrel is classified as an independent species within the genus of squirrels ( Sciurus ), which consists of almost 30 species. The first scientific description comes from Wilfred Hudson Osgood from 1944, who described the species on the basis of individuals from Peru in the area between the Rio Inambari and the Rio Tambopata , about 33 kilometers north of Santo Domingo , from a height of 570 meters. He named the species after the zoologist and taxidermist Colin Campbell Sanborn .

Apart from the nominate form, no subspecies are distinguished within the species .

Status, threat and protection

Sanborn's croissant is not classified in a hazard category by the International Union for Conservation of Nature and Natural Resources (IUCN) due to insufficient data on stocks, taxonomy and ecological needs, but is listed as "data deficient". It is believed that the species is threatened due to its limited range.
