Hoary Fox (Lycalopex vetula) lives in open savanna across South America. It feeds on small mammals insects. Its conservation status is Near Threatened.
Fascinating facts about the Hoary Fox
- The hoary fox relies primarily on insects, especially termites, dung beetles and grasshoppers, and also eats occasional rodents, small birds and fruit. Its weak teeth are adapted to feeding on invertebrates.
- Weighing only 3 to 4 kg, the hoary fox is one of the smallest members of its family, with a head-body length of 58 to 72 cm. Its tail adds another 25 to 36 cm, giving the animal a balanced, streamlined profile. The combination of its diminutive size and slender build makes it an agile, fast-running hunter across the savannah. These proportions, together with its weak teeth, reflect its adaptation to an insect-based diet.
- Home-range sizes vary widely, with a solitary adult female in southern Bahia covering about 385 ha. A breeding pair with five juveniles in a Minas Gerais pasture occupies a larger area of roughly 456 ha, reflecting the need for ample foraging ground. In eastern Mato Grosso, two breeding pairs were recorded using only 48 ha each, showing that richer habitats can support smaller territories.
- Male hoary foxes bear a distinctive dark stripe that runs along the upper side of the tail and can continue the full length of the back to the nape of the neck. This stripe stands out against the animal's grey upper body and the black tip of the tail, forming a clear dorsal line. The contrast is especially noticeable because the tail tip is black while the rest of the coat is a lighter cream or fawn on the underside.
- When it is time to give birth, a female hoary fox prepares a den and will often repurpose the burrows of other animals for this purpose. After a gestation of about 50 days, she usually delivers two to four pups in the late winter months of August to September. Both the mother and the father then share the duties of caring for the young, with the pups remaining in the den until they are weaned at roughly four months old.

About the Hoary Fox
In the arid landscapes of South America, the hoary fox moves with a quiet purpose, its grizzled coat blending seamlessly into the rocky outcrops and scrubby vegetation as it pads silently across the desert floor. With eyes that gleam like polished onyx, this cunning hunter navigates the harsh terrain with ease, its bushy tail twitching with every snap of a twig or rustle of leaves. As it pauses to survey its kingdom, the hoary fox exudes a sense of rugged resilience, a true embodiment of the unforgiving yet beautiful world it inhabits.
