About These Birds
Barn Swallow
제비는 세계에서 가장 넓게 분포하는 제비류이며, 어떤 참새목 조류보다 가장 긴 이동을 합니다. 북반구 전역에서 봄의 도래를 알리며, 고대 그리스에서 현대 시에 이르기까지 문화적 참고가 되고 있습니다. 제비는 둥지를 위해 인공 구조물에 거의 완전히 의존하게 되었습니다.
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.
