SUMMARY1Foxes treat different prey species in a variety of ways, eating, burying, or discarding them on the basis of preference.2Because foxes often utilize cached food and because they can remember which prey species is in a given cache the preference effect can be longstanding.3Evidence from the literature suggests that comparable effects of preference for different species of small mammals affects the diet of wild foxes and their behaviour in the same way as demonstrated in these experiments.4Certain distastes appear common to all foxes and most carnivores, for instance, insectivore and carnivore meat, in particular that of their own species.5An incidence of active cannibalism by a fox is reported.6The effect of food preference is shown to change during the course of one individual's life perhaps as a consequence of such factors as rearing cubs and competition for food.7One effect of the behavioural consequences of food preference is to defer the decision of what to eat.8That the fox will kill animals that it does not eat means that populations of animals that are not strictly fox prey are still at risk from fox predatory activity.

摘要:

ABSTRACTThe occurrence of wild foxes in suburbia is discussed. It is shown that in London breeding populations of foxes are found 5 km from the city centre, and in the last 3 years foxes have been recorded in the very centre of the city.The fox population in London is shown to be heavily dependent on residential habitats for both daytime harbourage and when selecting sites for natal earths. The fox population is unevenly distributed in London, with a marked clumping of the adult population during most of the year.The age structure of the population is presented, and these data are compared with data for other canid populations. Conclusions are drawn as to the effects of conventional control techniques on the age structure of a fox population.
