Foxes are typically a nocturnal animal, which means that they are awake & active at night time. It is easier for them to hunt for their food during the night as their prey (food) is usually settling down and trying to sleep. Foxes like other nocturnal animals have developed eyesight that allows them to see their prey at night. Plus during the heat of the day (like in summer) they are able to reserve their energy and not over heat themselves by hunting during daylight - so they hunt at night when it is cooler for them.
