Southern Amazon Red Squirrel (Sciurus spadiceus) lives in tropical rainforest across South America. It feeds on fruits and nuts. Its conservation status is Least Concern.
Fascinating facts about the Southern Amazon Red Squirrel
- The southern Amazon red squirrel is among the biggest squirrels in its range, reaching a total length of 48 to 63 cm. Its tail alone measures 24 to 34 cm, giving it a distinctive long-tailed silhouette. Both sexes are similar in size and carry a body mass of 570 to 660 g. The tail fades from dark brown at the base to orange along most of its length, adding a splash of colour to its otherwise reddish-brown coat.
- In lowland rainforests the species occurs at densities of 3.8 to 6.6 individuals per square kilometre, making it a common sight for researchers. Each animal maintains a home range of 25 to 50 ha, roaming across the forest floor and occasional canopy patches. Their non-territorial nature means several squirrels may share the same feeding tree, reinforcing the high local densities. Such abundance reflects the species' adaptability to both ground and canopy habitats.
- When a threat appears, the squirrel emits a distinctive alarm call that sounds like a sneeze followed by a chattering noise, alerting nearby conspecifics. Rather than leaping between branches, it usually drops to the forest floor, a behaviour that complements the vocal warning. This combination of sound and rapid descent helps the group respond quickly to predators such as ocelots and jaguars.
- Southern Amazon red squirrels do not defend exclusive feeding areas; instead, multiple individuals often gather in a single tree to eat. This non-territorial habit is reflected in their social feeding groups, which can be seen throughout their range where they are common.
- Although they spend most of their day on the forest floor among dense undergrowth, southern Amazon red squirrels can swiftly ascend trees when the wet season brings heavy floods. During these periods they retreat to the canopy, using their climbing ability as a quick safety measure. This behaviour complements their diurnal herbivorous lifestyle, allowing them to continue feeding on nuts while avoiding inundated ground.

About the Southern Amazon Red Squirrel
In the lush canopy of the Amazonian rainforest, the Southern Amazon Red Squirrel dances through the trees with effortless agility, its rusty-red fur blending seamlessly into the dappled sunlight that filters through the leafy boughs. With a twitch of its bushy tail, it launches itself from branch to branch, its tiny paws barely making contact with the bark as it weaves a intricate pathway through the forest's upper realm. As it moves, the squirrel's large, dark eyes shine with a keen intelligence, drinking in every detail of its surroundings with a quiet, unassuming intensity.
