About These Birds
Great Tit
The great tit is the largest European tit and one of the most studied wild birds in the world. Research at Wytham Woods in Oxford has monitored great tit populations since the 1940s, contributing enormously to ecology and evolution. These innovative birds famously learned to open milk bottle tops in 20th-century Britain.
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.
