乌鸦为什么是黑的

A gorgeous bird entranced by its own beauty sings and dances all day long in the forest, not caring enough to prepare for the winter. When winter finally comes, the bird has no place to go. After a while, there is a fire, and the freezing animal wants to limber up but in the end all his colorful feathers are singed and turn black as coal. And thus the once so beautiful bird has transformed into a black crow.
