About These Birds
Japanese White-eye
일본동박새는 동아시아 전역에 서식하는 작고 활발한 새이다. 뚜렷한 흰 눈 고리가 특징이며 올리브색과 녹색의 밝은 깃털을 가진다. 꽃의 꿀과 작은 곤충, 과일을 먹으며 숲, 공원, 정원 등 다양한 환경에서 생활한다.
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.
