There are several swan lakes in Perth, the capital of Western Australia, where hundreds of black swans roost, inhabiting the reserve, and the black swans live in harmony with other waterfowls, drawing a beautiful picture. The black swans here are not afraid of people, they can even chase people for food, if you have food in your pocket is found by it, it will put your mouth into your pocket to "steal", a cute look, let you can not help but be handsome. Little black swan is really ugly duckling, the beauty of the swan is gradually formed in the process of growth, this people have been very early recognition, otherwise "ugly duckling" how did the term come out? Australian black swans are not allowed to feed casually, however, and are also confused, black swans are chasing you tightly behind your buttocks, it is like a miserly child, can you refuse a child's plea?
