As far as I know, the woodpecker knocks on the tree to get to its prey, i.e. its food, among other things. This is different for other animals: predatory cats see their prey and chase it until they have killed it. The woodpecker knocks the bark of the tree until it splinters away and then he finds cavities where he finds the food. So he does something in faith without sight. That impresses me. He doesn't see it, but he is so certain that he will succeed - even if maybe not on the first try. Should you find yourself in a similar situation right now, where you need something but don't see it yet - then be encouraged and remember how you experienced before that you finally received and found all that was needed. And if it helps: Jesus says about our God: Your Father knows exactly what you need even before you ask.
I wish you an extraordinary day!
