Pupils help birds to survive the intense cold. They have built bird-houses and hang them near schools, nurseries, on the streets of cities and forest villages. Considering the frost, tree trunks are covered in ice, and it is hard for the bird kind to get natural food, and that is why many birds stay closer to people’s homes where it is easier for them to be fed.
Daily feeding of birds during hibernation is not only a considerable contribution into salvation of the bird kind, but also a great possibility to observe live nature, which is one of the most important means of fostering of a careful attitude to all living beings in children.
