Growing up in the NW suburbs of Chicago we had grey squirrels and they are really wild and hard to approach. I knew old tyme eastern Europeans DP's that used to shoot and eat them on some of our land. I personally never tried it or wanted to try eating one.
I never seen a red squirrel until I got to Iowa.
Than on Drake campus we had very gregarious big red squirrels that would literally eat out of your hand.
We also had the largest group of crows that I ever seen congregate in the city in my life, like 10's of thousands of them, it was creepy sometimes. Worthy of Hitchcock's movie "
The Birds". lol. [1]
• Video Link now multiply that by a thousand.
I never seen a grey squirrel on campus, I have no Idea how they compete with each other and how they take over an area. But I have not seen both of them
mixed in the same area.
But the big red ones on campus loved peanut M and M's
Made them really obese really. It got so bad we were advised not to feed them but its hard when they are used to it and right at you window regardless of the level of the dorm in the morning.
Newer news but it was going on in the 80's big time. So much corn around Des Moines its insane, like downstate Illinois but worse because they grow less soybeans.

Flocks of American crows have made their winter home in central Iowa towns and cities, causing big problems for pedestrians, the Des Moines Register said.
Thousands of noisy crows feed in farm fields and landfills during the day then head to town...

Also BTW the Des Moines Register in the last century was a highly respected newspaper, I have no idea what they are like now.
