In the nineteenth century they were considered a menace, leading to farmers and gamekeepers taking action to control their numbers. However, before the First World War fox hunters imported them from Europe for sport, helping in a really grizzly way to revive populations in the United Kingdom, and during the war many of those responsible for culling the red fox were sent to fight. Another contributory factor to their revival may have been myxomatosis in rabbits. Rabbits became a major part of the red fox food intake and this gave them a new form of food security. It is thought that the expansion of fox populations may well have driven adult foxes to seek new territories.
Foxes mate in winter and cubs are born early in spring but don't emerge until April. They come out mainly during evenings, but increasing numbers can be found enjoying the sun in the late afternoons.
