About These Birds
Red-tailed Hawk
The red-tailed hawk is the most widespread and common hawk in North America. Its screaming cry is so iconic that it is often dubbed over bald eagle footage in films and television. These adaptable raptors thrive in human-altered landscapes and are a familiar sight perched along highways.
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.
