The Garden Birds of Feathers Territory

On a lovely autumn day in a quiet neighbourhood village Feathers Territory is formed after some garden birds discover that seeds and nuts have been set out for them in most of the back gardens. This is a welcoming sight for the birds as they are aware that winter is approaching. The winter is very harsh. The garden birds soon learn they have to survive and occupy themselves in the very cold and snowy weather. Their life is never boring. They make use of all the facilities in the gardens and learn how to fend off their unwelcoming enemies. How do the garden birds manage to survive the winter?
