Which bird is stocking for the winter?

The jay, the most noticeable of wintering birds, is smart and beautiful.
This bird feeds on both plant and animal food, but the main food is acorns, hazelnuts and berries.
For the winter, he makes reserves for future use, and places them in pine or spruce forests, hiding them shallowly in the soil, and masking the cache with fallen needles and twigs.
The nuthatch also stores up for the winter – it stores its reserves in the cracks of the tree bark not far from its nest. But it can also eat in man-made feeders.
