About These Birds
Common Ostrich
타조는 세계에서 가장 큰 살아있는 새로, 키가 최대 2.7미터에 달한다. 날지 못하지만 시속 70km까지 달릴 수 있으며 아프리카 사바나와 초원에 서식한다. 세계에서 가장 큰 알을 낳는다.
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.
