There was a little brown bird that lived in a tree. The bird's name was Sadie.

Sadie wanted to build herself a nest, so she flew around the forest looking for twigs, feathers, and grass. 

Sadie stopped to take a break and saw something that did not belong on the forest floor. Sadie saw an empty bottle.

As Sadie looked around, she saw that there was a lot of trash in her forest. She did not know why anyone would leave these things here.

Sadie knew that there was too much trash for her to find what she needed for her nest. She thought for a moment, then had an idea.
