I know that cracked corn isn't good for squirrels, despite the fact that that's what retailers sell as 'squirrel food'. What are the best things for squirrel watchers to be tossing out to their backyard squirrels?
I know lots of people get squirrel blocks for them, but most of the people I know can't afford that kind of stuff. I'm just talking about relatively inexpensive, healthy corn alternatives.
