Garden birds spend up to 85 % of their day feeding just to survive. The fat reserves they build up during the day are used up over night when roosting in winter conditions. Here is a great way to make your own bird cake which will greatly help them through the winter. Keep your old glass jars (shallow with wide opening work best) and fill them with a selection of any of the following ingredients Mixed seed, Peanuts, sunflower hearts, black sunflower seeds, Nyjer seed, dried fruit, oatmeal. Then pour lard (waste fat or suet from your roasting tray , frying pan etc) in to the jars and it will make its way down through the seeds making it into a solid block. Let it cool and its ready to serve. Place the jar on its side on the bird table. Place a weight at each side of the jar to stop it from rolling. Sit back and watch the birds feasting.
