He'd peck...
hardwood, softwood, redwood, dogwood, cottonwood, plywood, hickory, beech,
rosewood, teakwood, sandalwood, and candlewood,
walnut, hazelnut, apple, and peach.
Then...
oak trees, elm trees, fir trees, pine trees,
pear trees, shoe trees, telephone poles,
barn doors, benches, table tops, and fences.
A woodpecker would peck a peck of little holes.
