One Woodpecker

ost birders I know have a weakness for woodpeckers. It’s partly the drumming that seduces us: that monotone hammering woodpeckers make every spring to claim a territory and find a mate. But it’s also their shape and color. Shape because every part of a woodpecker’s anatomy — bill, skull, ribcage, tail feathers, and feet — has been adapted to its peculiar foraging techniques on the trunks of trees.
