We used to have a Tree near us that was a Blue Jay tree. They
would peck and push a hole in the outer bark and then press in
a acorn. The acorn typically had a worm in it. The whole mess
would sit and cook all year and the birds would come back to
eat the pickled worms and nut while making more holes. The tree
looked like it was shot with a machine gun - a 50 cal - massive
array of 1/2" holes that were darker than the other wood.

probably scrub jays which are a lot like blue jays
they are the ones that plant oak trees since sometimes they
stash the acorn in the ground and forget where they put it

next thing you know you have an oak tree

smart birds and gregarious luckily their memory it not so good
