Rainforests and swampy areas. They are found in the Wet Tropics of Queensland, which is a World Heritage Area.

Physical Description/Characteristics

Cassowaries are one of the largest birds in the world at up to five feet tall and weighing in at around 130 pounds. Their heads and necks are a colorful blue with red wattles hanging below their beak. On top of their head is a brown, bony casque that looks similar to a large horn. Cassowaries are covered in stringy black feathers that are often mistaken for hair. Their long scaly legs have formidable feet at the end – one of their claws is six inches long, dagger-like, and can be used as a weapon.

Life Expectancy

In the wild Cassowaries live around 30 years, and in captivity they can live 40 to 50.


In the wild, Cassowaries eat mostly fruit, with the occasional small animal or insects. At the zoo he is fed a fruit and vegetable mix with pellets called Mazuri Ratite Diet, as well as grapes for a treat.


Cassowaries are solitary except for breeding, and when it’s time to have chicks, it’s all up to the male! Female cassowaries will lay their eggs in a nest made by the male, then will leave the male to incubate the eggs and raise the chicks. Chicks will be raised and protected by their father until they are around 9 months old.

Cultural Connections

The Cassowary is a respected animal in the culture of native Aboriginal peoples of Northern Australia, including the Girramay and Djiru. The Cassowary is called a “Gunduy” in the Girramay culture and there is a traditional dance modeled after its movement in the jungle. The Girringun Aboriginal Corporation describes the relationship with Cassowaries as follows: “Our people, the Rainforest Aboriginal people of Far North Queensland have lived with cassowaries for thousands of years or since Dreamtime.  These birds are an important part of our culture, stories, songs, dances and identity. Our rainforest aboriginal culture is interconnected with the Gunduy and our country. They are a part of us and are a very important animal for our rainforests and our culture.”

Conservation Connection

Vulnerable. In Australia, they are threatened mostly by habitat loss and habitat fragmentation. In New Guinea, they are threatened by hunting, especially as a food source.

The Zoo's Animals

The Zoo has one cassowary, a male named Emil. Emil was born on August 21, 1991. Emil is one of the only cassowaries in the United States trained to do blood draws and step on a scale. He has a specially designed “squeeze” crate which is a small holding area he is trained to get into. Keepers can feed him grapes through a window and draw blood from underneath his wing.

Fascinating Facts

They are also known as the Southern Cassowary. The Cassowary is the most dangerous bird in the world, and one of the most dangerous animals at the Birmingham Zoo (just like a lion or a tiger). Make sure to respect their space! Cassowaries have many different vocalizations, and the most notable is a low, guttural booming sound. The bony casque on top of their head is used to move vegetation out of the way as they move through the rainforest. It is not used for defense, as they use their claws for this.
