The Cassowary: The World’s Most Dangerous Bird

Fun Facts

Hello, everyone! Have you ever heard of the cassowary? While this enormous bird has a dangerous side with its massive body and sharp claws, it also has a surprising history.

The cassowary can grow up to 1.9 meters in length and weigh a staggering 85 kilograms! Its bare skin from the head to the neck is bright blue, and it sports a brown, bony crest on its head. Additionally, it has a red wattle hanging down from its throat.

These birds inhabit the tropical rainforests of New Guinea, Indonesia, and northeastern Australia. Although they can’t fly, they can run at speeds of up to 50 kilometers per hour thanks to their powerful legs. Their diet mainly consists of fruit, and they eat up to 5 kilograms a day! As they roam vast areas, they disperse the seeds of the fruits they consume, acting as “seed carriers” that help preserve the forest ecosystem.

Interestingly, there is a theory that cassowaries might have been domesticated by humans as far back as 18,000 years ago. It’s hard to imagine today, but the idea that ancient people might have kept cassowaries is quite fascinating. Incidentally, the first time cassowaries arrived in Japan was during the early Edo period. In 1635, a Dutch trading ship presented one to the Hirado Domain.

However, we can’t talk about cassowaries without mentioning their dangerous side! Their sharp claws, which can be up to 12 centimeters long, make them incredibly dangerous if they kick you. In fact, in 2004, they were recognized in the Guinness Book of World Records as the “world’s most dangerous bird.” It really highlights the power of nature!

You can also see cassowaries in seven zoos across Japan! Sadly, in the wild, they face a harsh environment where only 1% of chicks survive, and their numbers are declining due to habitat loss, putting them at risk of extinction. If you get a chance to see one in a zoo, take the time to carefully observe its imposing figure. You’ll be captivated by its strength and vibrant colors. Until next time!
