At the end of September, the colony of jays experiences an earthquake. Birds come from all sides. Everyone carries the throat after 12 acorns, a few may still fit in the beak. They cover their regular route dozens of times a day, from sunrise to sunset, for almost four weeks. During this time, the jay is able to place near the nest even to 10 thousand acorns. Each in a different clipboard! With such stocks, winter is not a threat to jays.
Such a flight is risky for life. This is because jays are poor flyers and have no chance of meeting a hawk or a sparrowhawk in the open.. That is why they only build their nests there, where they are able to hide: in the forest.
Jays' creativity in hiding winter supplies is enormous. They hide them according to a certain pattern. E.g: one jay hides its supplies 60 centimeters west of the large oak, her neighbor – meter east of this place. Their plan to hide their supplies for the winter is hard-coded in their heads! Therefore, as a rule, they find their treasures without much trouble under the layer of snow. However, many acorns remain in the ground until spring. This is not a coincidence: the young shoots developing from them are, after all, a great delicacy for chicks.
One spring I discovered it, that the jays chose a place under a large oak growing in my home garden for their winter pantry. It was close, that a real oak forest would grow under my windows!
