Food for thought! These large pileated woodpeckers were seen foraging on an incense cedar tree in search of ants, beetle larvae, termites, and other insects. Leaning their heads far from the tree and pulling back with their legs, these woodpeckers can strike a tree at speeds up to 15 miles per hour! How do they not get a headache? Powerful neck muscles absorb most of the shock while the bird's brain fits snuggly into its skull with little room to rattle around.
