Cassowary



Cassowary 
Cassowary is a bird . It is most dangerous bird than any other . It runs 70 km/h. It has sharp claw. It's among the largest bird in the world . It found in Australia.


Taxonomy, systematics and evolution 

Most authorities consider the above monotypic, but several subspecies of each have been described (some have even been suggested as separate species, e.g., C. (b) papuanus). Validation of these subspecies has proven difficult due to individual variations, age-related variations, the scarcity of specimens.


Behavior and ecology

While females move between satellite territories of different males, they appear to remain within the same territories for most of their lives, mating with the same or closely related males over the course of their life span. Courtship and pair bonding rituals begin with the vibratory sounds broadcast by females. Males approach and run with necks parallel to the ground with dramatic movements of the head, which accentuate the frontal neck region. The female approaches drumming slowly. 


Reproductive

Young cassowaries are brown and have buffy stripes. They are often kept as pets in native villages [in New Guinea], where they are permitted to roam like barnyard fowl. Often they are kept until they become nearly grown and someone gets hurt. Mature cassowaries are placed beside native houses in cribs hardly larger than the birds themselves.


Diet

Where trees are dropping fruit, cassowaries will come in and feed, with each bird defending a tree from others for a few days. They move on when the fruit is depleted. Fruit is swallowed whole, even items as large as bananas and apples.

SAVE ANIMALS
It's super-easy to help animals, no matter how old you are. Check out how Save Animals to get a jump-start on making a huge difference in the lives of animal everywhere: Animals are alive for their own reasons, not to entertain us. Animals in movies, circuses, and zoos are denied everything that is natural and important to them. They will never be allowed to hang out with their families, graze, or do anything that they would do in the wild. Refuse to support this cruelty by never going to a zoo, marine park, or circus that uses animals. If your class is planning on dissecting any animal, ask your teacher for a humane alternative assignment, such as using a computer program to perform a virtual dissection. An animal will be saved, and you will actually learn and remember way more! Check out more info on how to get a dissection alternative at your school.
