This old woodpecker reminds me of people who think more highly of themselves than they should. Usually they are so busy bragging about their achievements and their greatness that they fail to recognize God as the source of all their abilities. They are suffering from spiritual delusions of grandeur. Without the Lord no one amounts to anything, and in our own strength we cannot please Him.
Corrie Ten Boom used to tell the story about a proud woodpecker who was tapping away at a dead tree when the sky unexpectedly turned black and the thunder began to roll. Undaunted, he went right on working. Suddenly a bolt of lightning struck the old tree, splintering it into hundreds of pieces. Startled but unhurt, the haughty bird flew off, screeching to his feathered friends, "Hey, everyone, look what I did! Look what I did!"
