Grey wolf (Canis lupus)
Along with the lion, the grey wolf until 10,000 years was the most widespread mammal. It was absent only in South America, Australia and Antarctica. Its strong durability, high intelligence, his ability for collective hunt, its lack of fastidiousness to the food, made him an almost universal predator. Wolves hunt as mice and voles, as well as elks and bisons. It has been extinct long ago in large parts of the country. Today the wolf survives mainly in the mountains and its the number is between 800 and 1000 individuals. The wolf is classified as a vulnerable species in the Red Book of Bulgaria.
