largest woodpecker in the world
(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 56â60 cm (22â23.5 in) long. Researchers have discovered that the imperial woodpecker has slow climbing strides and a fast wing-flap rate compared with other woodpeckers.
