I know our red squirrels will “check out” my marten boxes. Also have had flying squirrels “check out” those baited boxes. I’ve read that they will eat bird eggs and young.

I once saw a grey come out of a dumpster with a chicken wing, set on top and eat it like a cob of corn.

A big fox squirrel is a common visitor to my bait pile.

Squirrels eat every baby bird they can find in the spring as will deer
