It is able to hear small mammals digging, chewing and rustling underground. Once a fox detects its prey, it rapidly digs into the soil to capture it. It will also stalk small mammals by standing very still, then leaping high and bringing its forepaws down to pin the animal to the ground. Red foxes will often store food for later, returning to their hidden supply of food when they are hungry. Young red foxes are primarily preyed upon by eagles and coyotes, while mature red foxes can be attacked by larger animals, including bears , wolves and mountain lions.

Humans are the most significant predator of adult foxes, who are often hunted for fur or killed because they are considered pests. Red foxes have a wide range of vocalizations that are used to fulfill a variety of purposes. The most commonly heard red fox vocalizations are a quick series of barks, and a scream-like variation on a howl. Their barks are very high pitched and sound like ow-wow-wow-wow.
It is commonly mistaken for an owl hooting. That bark sequence is thought to be an identification system and studies indicate that foxes can tell each other apart by this call. The scream-like howl is most often heard during the breeding season, in the springtime. It is thought that this call is used by vixens female foxes to lure male foxes to them for mating, though males have been found to make this sound occasionally as well.
Most other fox vocalizations are quiet and used for communication between individuals in close proximity. The most unusual is called "gekkering. Gekkering is heard among adults in aggressive encounters of which there are many; red foxes are highly territorial and also amongst young kits playing or play-fighting.

They also have an alarm call, which up close sounds like a cough but from afar sounds like a sharp bark, and is mostly used by fox parents to alert youngsters to danger. In a recent note to BBC Wildlife Magazine , Stephen Harris noted how, when the foxes and badgers first appear in his garden in the summer, they sniff each other carefully and then ignore one another, but get very agitated when a stranger turns up.
This, and many similar observations from other researchers, suggests that foxes are capable of recognising familiar and unfamiliar animals and that neighbouring territory holders may thus be able to recognise each other. Indeed, during the mids University of Washington psychologist David Barash trapped seven foxes and held them in cages so he could observe their reaction to each other. Despite the small sample size, Barash's data suggest that foxes can recognise their neighbours and that there may even be a rudimentary social structure between them.

This is perhaps not surprising as, in urban areas at least, neighbouring groups are often related. Newcomers to the area, Tinbergen noticed, acted quite differently:. Interestingly, there are also observations of foxes urinating in such a way as to suggest they may be trying to cover up their scent.
Adele Brand in Surrey and Catherine North in Manchester captured well-grown fox cubs urinating in a water bowl on their trailcams during August and , respectively. Similarly, West Sussex-based fox watcher Onyx Stewart tells me one of his adult vixens consistently did this in a tub of water in their garden, and Wildlife Online reader Tom Fitton has seen foxes do this during the summer in his garden in London. The fox was seen from a flat window and the observer didn't investigate the drain afterwards, so cannot be certain the urine entered the drain rather than being deposited on the grate, although this was the opinion of the witness.
It is difficult to understand, however, why an animal might deliberately contaminate such an important resource. Likewise, why it would deliberately dilute the impact of its scent mark if the goal is for others to read it? Why not, for example, urinate on the ground next to the water bowl, which will surely catch the attention of visitors?
Furthermore, Tom Fitton tells me that other foxes and badgers drink from the bowl despite the contamination, without apparently over-marking as they would ground-based scent marks, perhaps suggesting the scent is barely perceptible. Similarly, one might assume urine ejected into a storm drain is unlikely to be detectable to other passing foxes. Indeed, the observation that it tends to be subadult animals i. I would be interested to hear from readers with experience of this behaviour, particularly by adults during the winter or spring.
In Minnesota, USA, for example, wildlife biologists Robert Philips and David Mech found that a vixen they captured, translocated and released in November travelled the 56 km 35 miles back to her original capture site within 12 days. Similarly, in his book Foxes at Home , Colonel J. There are many factors that influence how much of a territory gets used and how far a fox will travel each night, although the impact of season is perhaps most significant.
The vast majority of tracking studies show the same trend: during the breeding season winter foxes travel further than they do at other times of the year. Indeed, during the breeding season males are known to move over large areas—regularly trespassing—as they search for receptive vixens, while females typically spend a greater proportion of the time at the periphery of their territories again, this probably facilitates mate-finding.
Studies in North America have found dogs increasing the length of their nightly movements by four to eight times come the breeding season. Interestingly, although no seasonal difference was found for females in Bristol, this may indicate that none became pregnant during the study.
Several studies have demonstrated how pregnant foxes move shorter distances around the time they give birth and for several days after the cubs are born. Seasonal variations in ranging may, however, be for reasons more subtle than searching for a mate or the birth of cubs.
Studies in Europe have shown that, during the late summer and autumn, foxes feed heavily on fruits that are locally clumped they can strip a bramble bush of blackberries in no time ; the result is that they need to move around less than they do during the summer or winter when finding food for cubs and when food is more difficult to find, respectively. Between and , Hideharu Tsukada at Hokkaido University studied the interaction and territorial behaviour of 42 foxes in Japan's Shiretoko National Park.
In his paper to the Journal of Ethology , he described a flexible territorial system associated with the distribution of food. When food was not concentrated, resident foxes were highly territorial, showing exclusive distribution of home ranges between families and defence against other foxes at the boundaries. Interestingly, when one male fox died, his territory was absorbed by neighbouring animals after about eight days. This suggested that localized food in other families' home ranges could be utilized by foxes without a high risk of losing their territories.

Generally speaking, foxes move roughly the same distance each night, although adverse weather conditions especially snow cover may reduce the distance travelled. In Bristol, foxes moved an average of eight kilometres 5 mi. Similar values have been recorded in Japan km and Spain 4 — 5. In the UK, the longest distance travelled by a fox that I have come across in the literature was a male that was tagged as a cub by Huw Lloyd at an earth in mid-Wales and was later shot by a gamekeeper 52 km 32 miles to the north-east.
More recently, however, Brighton University's Dawn Scott tagged an adult male fox in suburban Brighton that was tracked a staggering km miles from Brighton to Rye in East Sussex in just under one month. This particular fox, known to BBC Winterwatch viewers as Fleet, was believed to have been ousted from his territory by his son possibly as a result of his suspected lungworm infection ; he left Brighton on 9th December and in two days had reached the rural setting of Ditchling Beacon on the South Downs, some 7 km just over 4 miles away.
Fleet spent a couple of days on the South Downs Way before heading north-east, through various towns and villages and, by 18th December, he had travelled some km miles from his previous territory. He moved south briefly, towards the A27, and then back north to spend Christmas Eve and Christmas Day at a caravan park near Uckfield, where he was presumably fed by, or scavenging food from, residents.
Animal Facts: Red fox
The track continued to just north of Westfield in East Sussex, where the signal was lost during early January ; a total distance of km miles and by far the longest verified dispersal by a single fox in Britain. Moreover, Fleet's impressive ramble is not far off the current record for Red fox movement, which is held by a dog fox tagged in Wisconsin and recaptured nine months later km miles in Indiana. It should be noted that, despite a fairly extensive search of the area where the final signal was received, there was no sign of Fleet's body, suggesting that the collar may have failed, and Fleet's journey may still be in progress.
Foxes may temporarily leave their territory if there are highly concentrated food resources nearby. Overall, it seems that foxes focus most of their time at specific parts of their range generally feeding and resting spots , so they may move several kilometres, but stay in a relatively small area, often using only part of their range. After a gestation period of about 52 days, females give birth to litters that vary in number from 1 to 12, with 3 - 6 being common. Young are born blind and helpless, and are weaned by week 12 when they learn to hunt for themselves.
Both males and females play a major role in food acquisition for growing pups. Dens are usually found in abandoned woodchuck or other small mammal burrows, widened to suit the needs of a family of foxes. Their basic structure consists of the main channel, with a chamber or a widening of the main channel, lined with grasses and other forbs to make a dry refuge and birthplace for their pups.
Dens vary in location, and may be found among the root systems of large trees along the banks of streams or gullies, in or beneath hollow logs or hedgerows, or anywhere a woodchuck might decide to dig their burrow. It is common to find a den with multiple entrances. As temperatures in the den increase with the onset of summer, red fox will move the pups into a new den site every few weeks to minimize exposure to parasites such as fleas.
Females are ready to breed in their first autumn, but may not produce offspring until their second year. Dispersal among littermates varies by region, food availability, and habitat quality. Between the months of September and January territoriality between parents and offspring occurs after the rearing period has ended, thus resulting in the dispersal of offspring. Some individuals have been documented to travel over miles in search of unclaimed territories. The core of red fox social structure is the family unit, as this species is monogamous and actively defends their territories from other red fox.
Territorial disputes are seldom marked by violent encounters and usually consist of antagonistic displays, chasing, and harassment. Territories are maintained year round. Red fox are highly mobile and can cover long distances on a daily basis. Travel of greater than 6 miles is not unheard of.
Range expansion occurs during the winter months, presumably due to a decreased availability of prey, and contract during the rearing season. Displayed feces and scent posts marked with urine are evidence that red fox are wary of other foxes, and as a result territories seldom overlap.
