It was a moment of crisis when a man called 911 after being viciously attacked by a bird. “Can you send an ambulance? I'm bleeding to death,” said Marvin Hajos, 75, during the desperate emergency call. Police say he was attacked by his pet cassowary, which is said to be the most dangerous bird in the world, known for its dagger-like claws. Sadly, Hajos died of the injuries inflicted by his own bird.
