The cassowary: the most dangerous bird that challenges all predators

The cassowary, native to northern Australia and New Guinea, has earned the reputation of being the most dangerous bird in the world. Standing up to 2 metres tall and equipped with 10-centimetre claws, this winged animal is capable of causing fatal wounds with a single kick. Although its prehistoric appearance and aggressive behaviour when faced with threats make it look intimidating, they are actually shy and solitary birds, and prefer to avoid confrontations if not provoked.

Despite their danger, cassowaries play a fundamental role in the tropical ecosystem. In their natural habitat, they contribute to plant diversity by dispersing seeds as they roam the dense forests of New Guinea.

By feeding on fruits, snails, fungi and carrion, they help maintain ecological balance. As well as being a solitary ecological player, this species can run up to 50 kilometres per hour and jump great distances, making it an amazing animal in its natural environment.

Despite their ecological importance, cassowaries are not animals to be interacted with lightly. In zoos, zookeepers warn visitors not to get too close, as although they are not usually noisy, if they feel threatened, they can attack with lethal results.

Three types of cassowary have been recorded, with the smallest weighing 22 kilos and the largest weighing 70 kilos. Thanks to their large musculature and powerful claws, they can traverse virtually any surface, making them efficient predators and dangerous even to humans.

This ancient bird, with a lineage dating back to prehistoric times, continues to demonstrate its swimming skills and ability to survive in mountainous and humid environments. Its fearsome reputation is not undeserved: with its imposing appearance, speed and strength, the cassowary remains the king of the rainforest and a reminder of the powerful predators that still inhabit our world.

A surprising past: cassowaries as poultry

Surprisingly, some 18,000 years ago, prehistoric humans already interacted with cassowaries in a closer way than previously thought. Archaeological research suggests that these dangerous birds were bred as poultry in New Guinea. Despite their aggressive behaviour, young cassowaries were collected from their nests and raised to adulthood, revealing an ancient understanding of their handling. This unique relationship between humans and cassowaries highlights our ancestors’ ability to domesticate even the most fearsome animals.
