Correct sentence: In autumn, many animals, such as squirrels, make stashes for the winter.
Why this is better: The original sentence used the word "like" twice. We only need one idea to show an example. Using "such as" (or using just one "like") makes the sentence clear. We also use the simple verb "make" to say what they do regularly.
What "stashes" means: A stash is a hidden pile of food that animals save to eat later when food is hard to find.
Other simple ways to say it:
- In autumn, many animals, like squirrels, hide food for the winter.
- In autumn, many animals gather food to save for the winter.
