About These Birds
Scarlet Macaw
The scarlet macaw is one of the most iconic tropical birds with its dazzling tricolor plumage. These highly intelligent parrots form lifelong pair bonds and can live over 75 years in captivity. They play an important ecological role as seed dispersers in Neotropical rainforests.
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.
