"Fat balls and other fat-based food bars are excellent winter food. If they are sold in nylon mesh bags, always remove the bag before putting the fat ball out – the soft mesh can trap and injure birds. You can make your own bird cake by pouring melted fat (suet or lard) onto a mixture of ingredients such as seeds, nuts, dried fruit, oatmeal, cheese and cake. Use about one-third fat to two-thirds mixture. Stir well in a bowl and allow it to set in a container of your choice. An empty coconut shell, plastic cup or tit bell makes an ideal bird cake ‘feeder’. Alternatively, you can turn it out onto your bird table when solid."
