About These Birds
European Roller
파랑새롤러는 비행 중 구르고 굴러다니는 화려한 공중 묘기에서 이름을 얻었다. 수컷은 번식기에 이 공중 묘기로 암컷을 유혹한다. 밝은 파란색과 밤색이 눈에 띈다.
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.
