Monarch Butterflies Spectacular Migration
In order to escape from the cold of Canadian winters, every year monarch butterflies fly south to Mexican woodlands in one of the most spectacular animal migrations in the planet. Without any guides other than a form of magnetic waves, still a mystery and being studied by scientists, their instinct makes them fly more than 4,000 kilometers to hibernate in the Mariposa Monarca Biosphere Reserve. The reserve is in the West of the country in an area known as the Trans-Mexican Volcanic Belt pine-oak forests in the Mexican states of Michoacán and México.
