About These Birds
Barn Owl
헛간올빼미는 어떤 올빼미보다 가장 비대칭적인 귀를 가지고 있어, 동물계에서 가장 정밀한 청각 위치 파악 능력을 지닙니다. 소리만으로 완전한 어둠 속에서 먹이를 잡을 수 있습니다. 헛간올빼미의 독특한 하트 모양 얼굴은 포물면 접시처럼 작용하여 소리를 어긋난 귀로 집중시킵니다.
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.
