After Christmas, your tree can be moved outside and redecorated for the birds. Anchor the tree in a bucket full of damp sand. Hang strings of popcorn and cranberries and add strings of peanuts (in the shell). Apples, oranges, leftover breads and cakes, even peanut butter cookies, can be hung on the boughs, but don’t use food containing chocolate, as it is poisonous to some animals. For best results, push the edible ornaments well into the tree; things that swing may scare birds.
