About These Birds
Ruby-throated Hummingbird
The ruby-throated hummingbird is the only breeding hummingbird in eastern North America. These tiny birds beat their wings about 53 times per second and can fly backwards, sideways, and even briefly upside down. They make an extraordinary non-stop 800 km crossing of the Gulf of Mexico during migration.
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.
