The hoary fox or hoary zorro (Lycalopex vetulus), also known as raposinha-do-campo in Brazil (Portuguese for "little fox of the meadow"), is a species of zorro or "false" fox endemic to Brazil. Unlike many other foxes, it feeds primarily on small invertebrates such as insects.
Description
The hoary fox has a short muzzle, small teeth, a short coat, and slender limbs. The upper part of the body is grey, and the underside of the body is cream or fawn. The tail is black on the tip with a marked dark stripe along the upper surface, which in male animals may extend all the way along the back to the nape of the neck. The ears and outside part of the legs are reddish or tawny, and the lower jaw is black. Some melanistic individuals have also been reported.{{cite web|title=Lycalopex vetulus|url=http://animaldiversity.ummz.umich.edu/site/accounts/information/Lycalopex_vetulus.html|work=University of Michigan Museum of Zoology|publisher=Animal Diversity Web|access-date=30 October 2010}}
It is small for a fox, weighing only {{convert|3|to|4|kg|abbr=on}}, with a head and body length of {{convert|58|to|72|cm|abbr=on}}, and a tail {{convert|25|to|36|cm|abbr=on}}. Together with its slender form, the small size of the hoary fox makes it an agile and fast-running animal, while its relatively weak teeth adapt it to feeding on invertebrates, rather than larger prey.
Behaviour and diet
Hoary foxes are nocturnal,{{cite journal | author = Courtenay, O.| year = 2006 | title = First observations on South America's largely insectivorous canid: the hoary fox (Pseudalopex vetulus) | journal = Journal of Zoology | volume = 268 | issue = 1 | pages = 45–54 | doi = 10.1111/j.1469-7998.2005.00021.x|display-authors=etal}} and largely solitary outside of the breeding season. They mainly eat insects, especially termites, dung beetles, and grasshoppers,{{cite web | url=https://animaldiversity.org/accounts/Lycalopex_vetulus/ | title=Lycalopex vetulus (Hoary fox) | website=Animal Diversity Web }} but also may eat rodents, small birds, and fruit. Individuals have widely varying home ranges, depending on the local environment and reported examples are as follows: {{convert|385|ha|abbr=on}} for 1 adult female in southern Bahia, {{convert|456|ha|abbr=on}} for a group consisting of an adult breeding pair and 5 juvenile offspring in a pasture of Minas Gerais, and {{convert|48|ha|abbr=on}} for 2 breeding pairs out of 3 study groups from pastures in eastern Mato Grosso.
Range
The hoary fox is endemic to Brazil and its geographic distribution is associated with the limits of the Cerrado ecosystem, in an altitude range of 90–1,100 m. However, it can also be found in transition zones, including open habitats in the Pantanal. The occurrence of the hoary fox in areas of the Atlantic Forest is in a matrix of anthropogenic pastures, regionally interspersed by remnants of semideciduous forest and small patches of Cerrado.{{cite journal |access-date=19 July 2021 |author1=Dalponte, J.

The current extension extends from the northeast and west of São Paulo to the north of Piauí, passing through the states of Ceará, Mato Grosso do Sul, Mato Grosso, Goiás, Distrito Federal, Minas Gerais, Tocantins, Bahia and probably open regions in the south of the states of Rondônia.{{fact|date=July 2024}}
Reproduction
Females usually give birth to two to four pups in August to September, after a gestation period around 50 days. The sex ratio of the pups is equal between males and females. The female prepares a den in which to give birth, sometimes using the burrows of other animals. Weaning occurs around 4 months of age. Both parent participate in rearing of the pups.
