With these polar temperatures, many animals are in trouble and threatened with death from frost and snow. Among them are thousands of non-migratory birds.In most Croatian regions the ground is frozen.

To maintain the right body temperature, birds need to ingest a lot more food than in the warmer seasons, but unfortunately finding it is not easy. Ingredients - fat - polenta - bird food - seeds - net (for example, used for citrus fruits).

Preparation polenta and bird food into the fat. Put on gloves and shape the mixture into a ball. Then place the shaped mixture in a net and tie. The energy source is ready :)
