I have heard similar accounts of foxes digging up the bodies of foxes buried in people’s gardens, which has led to the suggestion that foxes may bury their dead (i.e. Roger Burrows described how foxes excavated and removed the bodies of foxes and badgers buried in his garden, in one case removing the head of a dead fox, although this should be treated with caution. Some authors have suggested that this happens during particularly harsh winters, although Stephen Harris observed cannibalism in the relatively food-rich habitat of suburban London (fox remains in six stomachs, accounting for 0.6% of the total diet), as did Brian Coman in Victoria, Australia (fox remains in 27 stomachs, accounting for just under 3% of the diet). red foxes, striped skunks, and raccoons were better able to find bait when it was cool and humid, presumably because such conditions cause scents to linger.”įoxes will occasionally scavenge carcasses of their own species.

The researchers found that 66 eggs and 87 starlings were eaten by raccoons, foxes and skunks the baits hung around for longer as wind speeds increased and they concluded that: In a paper to the journal Ethology in 2012, Ruzicka and Conover presented data from their study in which they distributed chicken eggs and dead starlings in various different habitat types around the Willard Bay Reservoir between May and August 2009. By contrast, hot, dry conditions cause scents to be quickly vapourised and dispersed within a few minutes. Indeed, it has been calculated that ideal scavenging conditions occur at wind speeds of between one and four meters per second (2 - 8 knots), with cool, humid conditions to allow the scents to linger in the air and on the ground. The reason for this is that wind speeds above about three metres per second (6 knots) causes air mixing and turbulence, which dilutes odours, making them more difficult to follow. In the Highlands of Scotland, foxes typically live singly or in pairs, so a group of 12 would indicate multiple neighbouring animals making use of this food resource.Ī recent study by Rebekah Ruzicka and Michael Conover at the Utah State University in the USA suggests that the weather conditions and the landscape in which a carcass is lying impact how easily a scavenger can track it down. They had clearly eaten their fill…” A Red fox caught on a remote camera scavenging from the carcass of a deer left out by researchers at the University of Wisconsin. One was rolling in the snow in the centre of the frozen burn, and others were gnawing lazily at the stag.

Others were bickering, and their yaps and yells sounded strange in a silence which seemed veritably to hiss. “ One or two of them were lying down, tidying themselves or gnawing the ice from between their toes. In his book, British Wild Animals, for example, Mortimer Batten described “a dozen foxes” surrounding a dead stag killed by the harsh conditions in the Highlands during the memorable winter of 1947. In their Mammals of the Soviet Union, Vladimir Heptner and Nikolaï Naoumov noted that foxes feed on carrion only in the late hours of the evening and overnight, leaving at sunrise (often to lay up nearby, where it may remain for several days, visiting the carcass periodically) – if the carrion is visited by wolves the fox, according to Heptner and Naoumov, follows after them early in the morning.Ī carcass may occasionally attract several foxes that will feed together it is unclear whether such aggregations of an ordinarily territorial species consist of related individuals, although some reports suggest not. shot, but not collected) during the hunting season. Indeed, following 641 miles of fox trails on three study areas in Michigan, USA, during two winters, led wildlife biologist Ray Schofield to 61% of the deer carcasses marked (i.e. They will also make use of any animals killed on roads or by hunters. Foxes are not averse to taking carrion and where they share their territory with larger carnivores (lynx and wolves, for example), they may shift their diet more towards scavenging from their kills.
