I thought that was squab, aka rats with wings...
When I was married, I used to do battle against squirrels, them raiding the bird feeders. The then-wife got me a book, something like "101 Ways to Fight Squirrels".
While the book was peppered with squirrel history and lore, I don't think any of the passive ways could beat a shooting contest, imho.
I'll continue to pass on even considering to consume them.
FWIW, pre-WWII editions of "The Joy of Cooking" have detailed instructions for skinning/cleaning fresh squirrel for cooking.
