In the revised generic classification, the hairy woodpecker was moved to the genus Leuconotopicus that was erected by the French ornithologist Alfred Malherbe in 1845. [10] [11] Some taxonomic authorities place the hairy woodpecker in an expanded Dryobates that includes all the species in the genera Leuconotopicus and Veniliornis. [12] [13]
The family's taxonomy is unsettled; the Clements taxonomy lists 235 species [2] and BirdLife International's Handbook of the Birds of the World lists 254 [3]. This list is presented according to the IOC taxonomic sequence and can also be sorted alphabetically by common name and binomial.
The downy woodpecker (Dryobates pubescens) is a species of woodpecker, the smallest in North America. Length ranges from 14 to 18 cm (5.5 to 7.1 in). Length ranges from 14 to 18 cm (5.5 to 7.1 in).

The largest surviving species is the great slaty woodpecker, which weighs 430 g (15 oz) on average and up to 563 g (19.9 oz), and measures 45 to 55 cm (18 to 22 in), but the extinct imperial woodpecker, at 55 to 61 cm (22 to 24 in), and ivory-billed woodpecker, around 48 to 53 cm (19 to 21 in) and 516 g (18.2 oz), were probably both larger.
Certain tree species are particularly susceptible to dying after being damaged by yellow-bellied sapsuckers. For example, a USDA forest study that examined trees injured by yellow-bellied sapsuckers noted a mortality of 67% for Betula populifolia , 51% for B. papyrifera , and 40% for Acer rubrum .
The name Leuconotopicus combines the Ancient Greek leukos meaning "white", nōton meaning "back" and pikos meaning "woodpecker".
