Hawk attacks postman in Calgary

A daring hawk attacked repeatedly a postman from Calgary, Canada. If everyone would expect a furious dog to be the number one enemy of the postal carriers, this time it turned out that a very aggresive hawk hunted repeatedly an employee of the Canadian post service, forcing the man in the end to wear a bike helmet. Still, this was not enough for the flying foe.
It looks like the hawk has a special hate for a single postman. The attaks started in june and increased in frequency and aggresiveness as well. The man began using a helmet for protection but the bird did not give up and continued the favorite attacking strategy. Following this threatening events, the postal services for about 150 homes in Calgary were suspended and the post office officials wait for the hawks to migrate to the south and this is expected to happen in a few days.
