Jay (Garrulus glandarius) - a watchful and timid bird known to all. He can warn other animals of impending danger. In autumn, she eats a lot of acorns and hides a lot of them in various places in the forest, stocking up for the winter - hence the long name of the acorn. However, not all acorns are found by jays in winter and young trees sprout from them in spring. This is how jays plant valuable oak forests and create mixed forests. Now is an opportunity to observe these cunning raven birds.
