About These Birds
Common Myna
The common myna has been named one of the world's 100 worst invasive species by the IUCN. Originally from South Asia, it has been introduced to tropical regions worldwide where it outcompetes native birds for nest cavities. Despite its invasive status, the myna is an intelligent and charismatic bird capable of mimicking human speech.
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.
