About These Birds
虎皮鸚鵡
The budgerigar is the third most popular pet in the world after dogs and cats, and by far the most common pet parrot. Wild budgies travel in enormous nomadic flocks that can darken the sky. Males can learn to mimic human speech, with one record-holding budgie having a vocabulary of 1,728 words.
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.
