They run all over the yard searching for nuts, eating the nuts, and burying the nuts.
A few have grown quite fat getting ready for their time of hibernation.
They might wake up a few times, as they sleep the winter away, but when they run out of food, they will scamper over the yard trying to find the nuts they have buried.
It's all instinct.
God, the Creator, gave them a way to survive the winter by sleeping and digging up the nuts they have hidden.
They just know how to do what they need to do to survive.
No one taught them.
They just knew how to do this when they were born.
God also ensured the propagation of trees through this instinct of the squirrels. The squirrels do forget where they bury all of their nuts and seeds. Where they are buried is where new trees will grow when the squirrels forget.
This reminds me of what Jesus said to His disciples. This is a go-to set of verses for me when
anxiety rears its ugly head and I forget the goodness of God.
“For this reason I say to you, do not be worried about your life, as to what you will eat or what you will drink; nor for your body, as to what you will put on. Is not life more than food, and the body more than clothing? Look at the birds of the air, that they do not sow, nor reap nor gather into barns, and yet your heavenly Father feeds them. Are you not worth much more than they? And who of you by being worried can add a single hour to his life? And why are you worried about clothing? Observe how the lilies of the field grow; they do not toil nor do they spin, yet I say to you that not even Solomon in all his glory clothed himself like one of these. But if God so clothes the grass of the field, which is alive today and tomorrow is thrown into the furnace, will He not much more clothe you? You of little faith! Do not worry then, saying, ‘What will we eat?’ or ‘What will we drink?’ or ‘What will we wear for clothing?’ For the Gentiles eagerly seek all these things; for your heavenly Father knows that you need all these things. But seek first His kingdom and His righteousness, and all these things will be added to you."
Matthew 6: 35-33
We have more than instinct.
We have God who not only loves His creatures, but who loves His children even more.
