Woodpecker, Satisfying video.

Woodpecker, any of about 180 species of birds that constitute the subfamily Picinae (true woodpeckers) of the family Picidae (order Piciformes), noted for probing for insects in tree bark and for chiseling nest holes in deadwood. Woodpeckers occur nearly worldwide, except in the region of Australia and New Guinea, but are most abundant in South America and Southeast Asia. Most woodpeckers are resident, but a few temperate-zone species, such as the North American yellow-bellied sapsucker (Sphyrapicus varius) and the flicker (genus Colaptes), are migratory.
