In Spanish, woodpeckers are known as
carpinteros--carpenters. Of course, we talk of woodpeckers "hammering" or "drilling" on a tree, but they are also hearty makers of sawdust, as illustrated here. After being upside down (below) in its cavity for a few minutes excavating a deeper and deeper cavity for its nest, this flicker turns right side up with a beakful of debris which it then flings to its left. Without fail, both male and female at this Lake Union nest perfom their nestbuilding exactly this way, hour after hour--always throwing dust to the left.
