(Gould, 1832) The imperial woodpecker (Campephilus imperialis) is a member of the woodpecker family, Picidae. The genus Campephilus is essentially a tropical one, embracing 13 species, including the imperial woodpecker. If it is not extinct, it is the world's largest woodpecker species, at 56â60 cm (22â23.5 in) long. Researchers have discovered that the imperial woodpecker has slow climbing strides and a fast wing-flap rate compared with other woodpeckers.
