About These Birds
Japanese White-eye
O olho-branco-japonês é uma pequena ave verde-oliva com anel ocular branco característico, muito popular como canário de gaiola no Japão e amplamente distribuído na Ásia.
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.
