The energy expenditure of chasing and fighting during the breeding season can result in a buck losing an immense amount of weight, with some research documenting losses of as much as 20% of body weight with some sources showing body mass losses of up to 30%. [11] On average, a buck before breeding season can weigh up to 180 pounds (82 kg).
In doing so, kit foxes exercise the economics of water at the cost of energy. [6] The apparent velocity of kit foxes is essentially an illusion created by their limited size and cryptic coloration, and their incredible ability to evade and change directions. An accurate account clocked a fox kit at around 40 km/h in front of the car, but the ...
In their summer camps, starting in January, male grey-headed flying foxes set up mating territories. Mating territories are generally 3.5 body lengths along branches. [28] These flying foxes' neck glands enlarge in males in the mating season, and are used to mark the territories. [28]
The gray fox (Urocyon cinereoargenteus), or grey fox, is an omnivorous mammal of the family Canidae, widespread throughout North America and Central America.This species and its only congener, the diminutive island fox (Urocyon littoralis) of the California Channel Islands, are the only living members of the genus Urocyon, which is considered to be genetically sister to all other living canids.
Bengal foxes are thought to form long-term monogamous pairs, but this supposition is based on scarce evidence [13] and extra-pair copulations are known to occur. [citation needed] During the breeding season, males vocalize intensely during the night and at dusk and dawn. [13]
During the breeding season, in southern hemisphere winter the months of July and August, [14] monogamous pairs may occur, but the duration and persistence from year to year is not well known. [4] [11] Paired adults typically only have contact during the mating season, [4] but mouth sniffing or nuzzling ("greeting") occurs, as does body slamming ...

Conservationists had to take healthy breeding pairs out of the wild population to breed them in captivity until they had enough foxes to release back into the wild. [30] Nonnative grazers were also removed so that native plants would be able to grow back to their natural height, thereby providing adequate cover and protection for the foxes ...
