About These Birds
Emperor Penguin
황제펭귄은 모든 펭귄 중 가장 크고 무거운 종이다. 남극 겨울에 번식하며 영하 60도의 혹독한 추위를 견딘다. 수컷이 두 달 이상 알을 품는 동안 먹이 없이 버티는 것으로 유명하다.
Southern Cassowary
The southern cassowary is often called the most dangerous bird in the world due to its powerful legs and dagger-like inner claw that can reach 12 cm in length. Despite this reputation, cassowaries are vital rainforest keystone species, dispersing seeds of plants that no other animal can. The purpose of their distinctive casque remains debated.
