Mission Critical: Dino Bird 關鍵任務 —— 恐龍鳥 Learn about this giant bird that is as dangerous as its dinosaur ancestors. 來認識一下這種巨鳥，牠和牠的恐龍祖先一樣危險喔。
Australia is home to amazing and strange animals that are some of the deadliest▼ on Earth. The southern cassowary▼is no exception. It rules the jungles of New Guinea and northeastern Australia. However, their populations have been dropping all across their range. National Geographic film crews traveled to one of the oldest rainforests in the world to track this giant bird to find out why in Mission Critical: Dino Bird. The southern cassowary is a giant, flightless▼ bird that looks like something which belongs in the age of the dinosaurs. Its neck is bright blue and red, and it has a large, bony crest▼ on top of its head. Standing nearly 190 centimeters tall and weighing in at around 85 kilograms, these birds are the biggest thing in the rainforest. As if that weren’t enough, these dangerous birds have a large, knife-like claw on each foot. Though they eat mostly fruit, they are still really dangerous when in danger or scared. Cassowaries have even been known to use their powerful legs to kill both dogs and people. This month, National Geographic heads to Australia to follow a cassowary named Bertha in Mission Critical: Dino Bird.
