About These Birds
Common Starling
紫翅椋鸟（Sturnus vulgaris）— 原产于欧亚大陆，已引入北美、澳大利亚和南非。具金属光泽的羽毛和白色斑点为特征。能形成壮观的大群（椋鸟旋舞）。
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.
