Animal Encounters XIV

Hello there folks! I hope everyone is well and warm in this cold but refreshing month of Febuary. The latest animal from Bristol Zoo to grace this page is a very elusive animal.

The Cassowary




The double-wattled cassowary is one of the largest birds in the world. Weighing as much as 128 pounds, only the ostrich is heavier. Flightless birds, cassowaries are covered in coarse black feathers, with the exception of the skin on the head and throat which is brightly colored red and blue. These coarse feathers are an adaptation to the thick vegetation of the rain forest where cassowaries live. The flight feathers are reduced to five or six quills on both sides of their body that protect the bird when it is traveling through the undergrowth. One of the cassowary's most distinguishing features is the large protuberance on the top of its head called the casque.

It is believed that the casque assists the cassowary in pushing through the dense tropical forest vegetation, and may also provide some sort of protection. In captivity, cassowaries have been observed using their casques like a shovel to search for food on the ground. It is believed that the size of the casque may indicate dominance and age, since the casque continues to grow throughout the life of the bird. Another distinguishing feature of the cassowaries is their wattles. Wattles are present in two of the three species of cassowary. These brilliantly colored folds of skin hang from the bird's neck, and may act as social signals in the dark forest. Cassowaries have powerful legs and feet that enable them to run up to 30 miles per hour and jump as high as five feet. Their feet are equipped with sharp claws and the inner toe is formed into a long dagger-like claw that can be a formidable weapon.

Double-wattled cassowaries are found in New Guinea and northern Australia. They are most often found in the rain forest, occasionally straying to swampy forested areas. They are excellent swimmers and are often found along river banks. Cassowaries are very important to the native people of New Guinea both economically and ritually. Cassowaries have been traded for pigs and even for a wife. Some tribes hunt them for their meat which is considered a delicacy. They use the feathers to decorate headdresses, and the feather quills for earrings. The sharp claws are often placed at the tips of arrows, while the strong leg bones are used as daggers. Cassowaries have been traded throughout Asia for at least 500 years, and it is believed that this is how the double-wattled cassowary reached Australia. For many native people, cassowaries are full of legends and mystical powers. Some tribes believe that cassowaries are reincarnations of female ancestors, while others believe that the cassowary is the primal mother. These tribes do not hunt or deal in trade with cassowaries.

I'm shy!

Although none of the three species of cassowary are globally threatened, all are suffering from loss of habitat. Their strict ecological needs mean that they are especially vulnerable to shrinking habitats. As rainforests are cleared, cassowaries are forced from one forest to another, often crossing roads where they are in danger of being hit by passing cars. Introduced feral pigs and dogs prey often upon chicks. In New Guinea, an increase in the price of cassowary feathers by the native people, has led to an increase in hunting of the cassowary.

On a seperate note, I've just moved houses and am now settling in. As always, I find the process of moving traumatising and troublesome. The decision to keep some useless junk for sentimental values compared with the need to be practical and realistic always have me gnashing my teeth and pulling my hair out at the end of the day. This goes to show what a stubborn old dog I've become ......
