How A Woodpecker Pecks Wood

If you’ve heard the hammering of a woodpecker in the woods, you might have wondered how the birds can be so forceful. What does it take to whack your head against a tree repeatedly, hard enough to drill a hole? A team of researchers wondered that too and set out to investigate, by putting tiny muscle monitors on eight downy woodpeckers and recording them with high-speed video as they pecked away in the lab. Science Friday

A team of researchers at Brown has pecked away at the mysterious force of woodpeckers, revealing how the birds combine breathing and whole-body coordination to drill into trees with extraordinary force. “I think one of the most stunning things that we found in this study was that… they’re engaging everything from head and neck muscles, which you might expect, all the way down to muscles in their tail and hips as they push forward during these strikes,” said lead author Nicholas Antonson, a postdoctoral research fellow in ecology, evolution and organismal biology at Brown.
