Is it safe for squirrels to eat bread?

Last week my mom put out some stale wheat bread in a couple smaller trees next to our house/porch for the birds. But the birds never got it because there s this squirrel that likes to venture really close to our house that found it. And ever since, he s been coming back to our porch to feast on bread. He s really quirky and adorable. My mom and I named him Cornelius. We ve been leaving him a slice of bread since.

But the more I got thinking about it, the more I wondered if bread was really safe for squirrels to eat?? So yesterdsy I put a strawberry out with the bread. Soon enough, he came and ate the bread but he didn t touch the strawberry. I figured he must ve been full and that he d come back later for the strawberry. He did come back to scout for bread but he still refused to eat the strawberry. I put apple out today with the bread and he did the same thing.

Cornelius really seems to like bread but is it good for him?
