An extremely distinctive curiousity of a bird - the Magnificent Frigatebird is the largest, most famous and widespread of the frigatebirds. Perhaps best known for the males possessing a bright red inflatable throat balloon that they use for mating displays. They also are one of the fastest birds in the world capable of moving up to 153km/h. Their feeding habits are a mix of catching fish from the water and using their speed, size and power to kleptoparasitise other seabirds, forging them to regurgitate their own catches.
