Jays are birds that like to hide their food, like acorns and hazelnuts, in many different spots. Sometimes, they forget where they put their food. When this happens, the nuts can grow into new trees. This helps the forest become stronger and full of healthy trees. So, even when jays forget, they are helping the forest grow!
Another way to say this is: Jays store their food in lots of places but often don't remember all their hiding spots. The seeds they leave behind can sprout and grow into trees, making the forest a happier and healthier home for many animals.
