Thomas Pennant had provided Brown with a drawing of the bird. The blond-crested woodpecker is now one of 13 species placed in the genus Celeus that was introduced in 1831 by Friedrich Boie. The blond-crested woodpecker has two subspecies, the nominate C. f. flavescens (Gmelin, JF, 1788) and C. f. intercedens (Hellmayr 1908). What is now the ochre-backed woodpecker (C. ochraceus) was previously included as a third subspecies. == Description == The blond-crested woodpecker is about 27 to 30 cm (11 to 12 in) long. The nominate subspecies weighs 110 to 165 g (3.9 to 5.8…
