In Spain there are two species of foxes found in the wild: the red fox (Vulpes vulpes) and the arctic fox (Alopex lagopus). The red fox is a very common species in Spain, both in the countryside and in urban parks. These animals are of medium size, with a body length between 50 and 70 cm and a weight between 3 and 7 kg. Their fur is generally dark gray with white, brown, or black markings. Males are usually slightly larger than females. These animals are omnivorous, feeding mainly on fruits, insects, bird eggs, and small vertebrates.
The arctic fox is a subspecies of the red fox found mainly in northern Europe and Asia. It is adapted to live in cold climates with freezing temperatures for long periods of time. Its fur is white during the winter months to better blend in with the snow; however, during the warmer months it is usually dark gray with white or black spots. Like the red fox, this subspecies also feeds mainly on fruit and insects; however, unlike the former, they can survive long-term without drinking water thanks to their moisture-rich diet.
