Kea

kea parrots live in New Zealand. Accustomed to a person and very curious birds sometimes damage the machines, their tents and booths in search of food residues; they are attracted to places of landfills and waste containers, and often they dumped the contents on the ground; very playful, like somersaults in the snow or take a bath in the newly thawed pools. These birds can eat like carrion and live sheep attack. Parrot uses a clever tactic: he sits on the ground near the victim and then suddenly jumps on her back and vyklёvyvaet pieces of fat, causing extensive sheep wound. If a sheep abruptly dumps him, he tries again. The finale of this story is usually sad: Sheep runs with the "rider" on the back, is a run it will not lead to the death, even if the animal manages to get rid of the annoying bird, later it is still ill or dying because of wounds received. It also happens that backed parrot sheep falls from cliffs and splits. And then the carcass immediately flock to flock Kea.
