Which of the four main subfamilies of Picidae contains the vast majority of true woodpeckers?

Picinae

The family Picidae, which encompasses almost 200 species worldwide that share adaptations for excavating wood, is further broken down into subfamilies to organize observed diversity in shape, size, and behavior. The subfamily designated as Picinae is recognized as containing the vast majority of what the general public recognizes universally as woodpeckers. These are the iconic species characterized by possessing strong bills capable of drilling and stiff tail feathers that are utilized as props or braces when they are hammering into wood surfaces. Although the precise taxonomic groupings can sometimes show slight variations depending on the ornithological perspective adopted, Picinae remains the core group for the typical, drilling woodpecker.
