Pampas Fox Habitat

The Pampas Fox is a common sight in the Southern Cone Pampas grasslands and enjoys open habitats and tall grass plains. It is also often found in more arid and semi-humid regions, along with scrub lands, coastal sand dunes, open woodlands, and even grazed pastures and croplands. In the driest regions, it is replaced by the Chilla Fox.

Where its range overlaps with that of the Crab-eating Fox, the Pampas Fox will choose more open areas. Despite the extensive cattle breeding and agricultural activities that have altered its home, the Pampas Fox has proven surprisingly adaptable.

In a coastal area of northern Patagonia, the Pampas Fox was observed using all available habitats. Radio-collared Pampas Foxes seemed to prefer the more intact grassland and cropland areas of the Argentine Pampas, though their preference was even stronger in the most modified habitats.

Territorial Behavior

The Pampas Fox is a nocturnal, solitary, and territorial animal that marks its territory by defecating at specific latrine sites. This behavior has social implications as it allows other foxes to recognize the territorial boundaries and avoid confrontation. Scent marking techniques are also used to communicate with other foxes and to deter potential predators.

Territory size variability is common among Pampas Foxes, but they usually range around 260 hectares, equivalent to 640 acres. This territory is used for hunting, mating, and raising their young.

Intra and inter-species competition can occur when individuals compete for resources, and territorial disputes may arise when a fox crosses the boundary of another fox’s territory. Overall, territorial behavior is vital to the survival and reproduction of the Pampas Fox.

Where Do Pampas Foxes Make Their Dens?

Pampas foxes can den in any available cavity, including caves, hollow trees, and the burrows of viscachas or armadillos. They also construct their burrows, with entrances usually facing South or Southeast to avoid direct sunlight and strong winds.

The mate selection process is crucial in determining the den’s location. Once a pair has chosen each other, they will work together to construct a suitable den. They will also mark their territory by defecating at specific latrine sites.

Sometimes, multiple pairs of foxes may share a den, but only if they are closely related. The den’s location is also important for predator avoidance, as they are vulnerable to attacks from larger predators such as pumas and jaguars.

Pampas Fox Appearance

The Pampas fox is similar in size and shape to the culpeo or Andean fox but has a wider snout and reddish head and neck. Its short and thick fur is grey for the most part, and a black line runs down the back, ending on the tail. The underside is a light, nearly white color.

The ears are large and broad with a reddish external surface and a white internal one. The inner side of the legs is the same color as the underside, while the outer part of the forelimbs is reddish, and the hind limbs are grey, with a dark blotch on the lower leg.


Pampas fox can weigh between 5.3 to 17.6 lb and grow up to 31 inches in body length!

However, their size can vary across different regions, with those living in the northern parts of their range appearing larger and more richly colored.

There isn’t much variation in size differences between males and females. Both sexes are similar in size, with males only being slightly larger.

Factors affecting the size of Pampas foxes are not well known, but it’s believed that genetics and food availability may play a role.
