This article does a great job asking and uncovering the nuances and previous misconceptions around the question of how woodpeckers can sustain their pecking without suffering traumatic brain injury. My frustration with this piece is that is spends 95% of the article posing the question in various ways, and then only a few quick sentences without further explanation or elaboration to answer it. All we're left with is "they have smaller brains" and no further scientific breakdown as to why that minimizes any possible brain damage. I'm left a bit disappointed from the otherwise fantastic journalist Ed Yong.
