Tut my M2 is over 20 y.o. and just recently started doing this.
For his shredding pleasure, I give him telephone books. He will shred them and fill up the bottom of his home with about 12 inches of paper. I've noticed a depression in the pile that is clean and poo free.
No problem with him doing, just strange that he has never done this.
We allow our males to build nests in the bottom of their cages, too. A word of caution though, they can get very defensive of their nests, if you haven't already found that out. You may find that you need to scale back the amount of time you let him do this, i.e. once a week instead of once a day.

Elliot, is your M2 a male? Ours is about 20 and we think he's a male (black eyes) but not certain. He occasionally tears up paper and puts it in a corner on top of the cage. I always thought he was just making a mess. A too wouldn't build a nest if he lives with a macaw, would he?
Hi we have a U2 at work that builds nest. He doesn't live with other birds, not in the same room anyway. Fred and Patty Chicken live in the next room. During breeding season he gets very aggressive around his box. We cut back on how often he gets one. It helps alot. Nancy
My situation with Tut is he was abused before I got him in '87. He is not really aggressive as much as he is very hand shy. He still takes food from my hand gently. Any thing he does that is to his overall comfort and not harmful to his physche, I let him.
I'm not 100% sure he's male, but when he was with a Goffin I had, they used to do the wild thing.
I have never had him on my arm. He will step up to a perch rod. He will take food by hand and eat mush from a spoon. He isn't a screamer, but will crank up every now and then. He is sneaky though. He will imitate the Quaker or the Scarlet or the U2.
What kind of life he had before I became his guardian, I don't know. But he will have the best I can give him. My only hope is for Tut to trust me and know that I'm not going to hurt him. If I never get him to allow cuddles or touching, that's fine with me.
We've only had Brewster for a little more than a year & he's never "nested". He loves to shred stuff up though! I would think for a bird Tut's age that he would have done that before. I read somewhere on a rescue site that they determine an adult M2's sex by the size of his beak The male's beak is much larger than the female's! I'm not sure....the beak is sooooo big Since Tut will live a long time, you are doing great on your progress! He sounds like a sweet bird!
