The idea that a woodpecker's tongue provides cushioning for their brain as it wraps around their skull has come into question. The newest calculations, made with the most accurate modern technology, refute the idea that a woodpecker's brain is cushioned at all!

Of course, any of these conclusions might be proven wrong or incomplete as scientists discover new information in the future. The beauty of science is that it requires us to be able to change our minds in light of new evidence. One thing that doesn't need to change is the magic we feel when we watch a great black bird with a flaming topknot spread their broad wings and with a few swooping beats disappear into the forest.
