Cassowary in the future

A cassowary is the second largest bird in the world, and it is considered to be the most dangerous bird in the world. The cassowary cannot fly . They are generally jet-black with brightly colored skin of their heads, they have a huge horn that is used as a shock absorber when they push through the rainforest, and large powerful legs. They can run up to 31mph and jump up to 7 feet into the air, and swim really well, on the end of their feet are three dagger-like toenails. In the future, assuming they survive, they would probably be smaller, but maybe even faster. the horn would be smaller as well but they would still have the powerful legs for running through their habitat and escaping danger.
