Cassowary, AustraliaBehold the cassowary, declared by the Guinness Book of World Records to be “the most dangerous bird in the world.” The distinction is mainly due to its huge claws that it uses to defend itself, usually aiming for the torso of would be intruders, human or otherwise. Native to northeastern Australia and Papua New Guinea, it is the third largest bird in the world behind the ostrich and the emu. Like those birds, it is flightless, and it can grow to over 6 feet tall and weigh more than 150 pounds. Lucky for me I had a 600mm lens on my camera and could photograph from a safe distance.
