This bird def was trying to eat it. Flew down with such motive, picked it up, disappointed all across his or her face, dropped wrapper, went to a crumb or some food.
Look up how many bird skeletons and cadavers (weird word) they (researchers, humans, people…) find loaded with plastic in their bellies.
Fish are shiny objects and excellent sources of protein, and so are a variety of insects. Plastic is not found in nature. Nor are spaceships.
