I keep a hanging basket of shredded paper, torn-up cardboard, shelled peanuts, plastic bottle-tops and other bits and pieces. The birds (especially Dominic) love to dive into it and hurl things out while finding their favourite pieces to munch on. I spread newspaper underneath it and so it's simple enough to scoop up all the confetti when they've finished playing and toss it out.
take some paper muffin cups but some treats inside wist them and put them into coffee filters and tie them closed.
I do this everyday doesn't get old.
Take an string and some bottle caps,put holes in the bottle caps and put 2 together tie a knot above and repeat then put treats inside.
