    Long ago,Bluebird's feathers were the colour of dust. She did not like her ugly colour.She was attracted

by the colour of the lake near her home. It was as blue as the sky after a storm. Bluebird wanted to be the

colour of that beautiful lake very much.

    Flapping her wings one morning, Bluebird flew from her tree to the blue lake. Then she bathed in the water

three times. After each bath, she sang, "Blue water. Still water. I went in. I am blue. " Bluebird repeated this every

morning. On the third day, she came out the lake with beautiful blue feathers.

    Now Coyote was a trickster (骗子) —and hungry too. He stayed behind Bluebird 's tree for a long time every

day and watched her go to the lake. He pretended (伪装) to be interested in everything she did. He wanted Bluebird

for lunch, but he was afraid of the blue water.

    On the third Morning, Coyote saw Bluebird come out of the lake with beautiful blue feathers. Impressed, he

sat next to Bluebird's tree and waited for her. When she returned, he asked, "How did you get blue feathers? I

want to be blue like the mountains too. "Bluebird didn't believe Coyote, but she taught him how to bathe three

times each morning and how to sing her song. Coyote did what she said, and after three days of bathing in the

lake, his white fur turned deep blue.

    Convinced (确信的) that blue fur was even more beautiful than blue feathers, Coyote forgot all about being

hungry. He ran as fast as he could to the top of the hill. Standing on his back legs, he raised his front legs off

the ground and howled. But Coyote slipped (滑倒) and rolled down the hill. He couldn't stop himself,and the dust

and dirt covered his new blue fur. He rolled and rolled until he hit into Bluebird's tree heavily. No matter how

much he tried, foolish Coyote could not shake the dust from his fur. And so the fur of all coyotes has the dull

colour of dust to this very day.
