Why The Sky Has Pretty Colors

When walking back from class, I looked up to the gray sky of winter. This made me think of the summer when the sky changes from blue to pink and even a shade of red at times. I then thought to myself, "how does the sky have that many colors?" Thats when it hit me, the birds. The birds spend all day flying around, sometimes in what seems like unnecessary patterns. When they are doing this, they are simply painting the sky. The next time you see a flock of birds, don't hide and duck, look closely and you will see tiny paint brushes in their beaks. With this simple explanation, no one will ever have to wonder why the sky has pretty colors ever again.
