The woodpeckers family members are found almost worldwide. Most species live in forests or woodland habitats, although a few species are known to live in treeless areas such as rocky hillsides and deserts. They range in size from 8-50 cm. Many species exhibit patches of red and yellow on their heads and bellies, and these bright areas are important in signalling. Although the sexes of Picidae species tend to look alike, many have more prominent red or yellow head markings in males than in females.
Members of the family Picidae have strong bills for drilling and drumming on trees and long sticky tongues for extracting food. Species that use their bills in soil or for probing as opposed to regular hammering tend to have longer and more decurved bills. To prevent brain damage from the rapid and repeated decelerations, woodpeckers have evolved a number of adaptations to protect the brain. These include small brain size and the short duration of contact. The millisecond before contact with wood a thickened membrane closes, protecting the eye from flying debris. The nostrils are also protected, they are often slit-like and have special feathers to cover them. In addition to the strong claws and feet woodpeckers have short strong legs, this is typical of birds that regularly forage on trunks. The tails of most woodpeckers are stiffened, and when the bird perches on vertical surfaces, the tail and feet work together to support it. Picidae species can either be sedentary or migratory.

North American Woodpeckers
Golden-fronted Woodpecker Image by Andy Morffew
The article describes six woodpecker genera:
Dryobates, Leuconotopicus, Melanerpes, Picoides,
Sphyrapicus, and
Xiphidiopicus. They are mainly found in North America and Central America which eographically is really part ot North America, its tail end. Since South America is connected to North America, it is not surprising that these genera contain a considerable number of its South American species also.
Of the 5
Dryobates species listed here, 3 are found in North America and the others in Europe and Asia. On the otherhand, Clements Checklist of THE WORLD BIRDS places 31 species in this genus. In particular, it places in
Dryobates all the species that others have in
Leuconotopicus and
Veniliornis. The
Dryobates woodpeckers that are treated here are relative small with a length of 14 to 19 cm. The North American species (downy, ladder-backed, and Nuttall's woodpeckers) all have black and white plumage, except for some red on the head. They forage on trees and eat mainly insects.
There are six
Leuconotopicus woodpeckers. All except the smoky-brown woodpecker which is found in South America, are restricted to North America. They are medium sized woodpeckers with a length between 18 to 24 cm. They mainly eat insects, but also fruit and seeds. Their nest is usually excavated in a dead tree or a dead branch of a living tree.
Most of the North American woodpeckers are members of
Melanerpes. Twelve of the
Melanerpes species are just found in North America, three species in North and South America, and five are found just in South America. More so than most woodpeckers, the Melanerpes woodpeckers have a varied diet. Most prefer insects, but also eat other arthropods, fruit, and seeds. Some cache nuts for future consumption. And a fair number of these species will catch insects on the fly. Their name means "black creeper". These woodpeckers all have some black on their upperparts and all have black bills. They range from the white-fronted woodpecker with a length of 16 to 18 cm to the West Indian woodpecker with a length of 28 to 30 cm. In all cases, the sexes are of similar appearance. Usually there are coloration difference on the head, with the male being brighter. The Guadeloupe, Lewis's, and the red-headed woodpeckers cannot be sex differentiated based on appearance. Most of these species excavate their nest cavities in dead trees or dead limbs of living trees. Live trees are also used by some species. When available, cactus are also excavated for nest cavities - they are relatively soft for easy excavation and cactus thorns can afford protection from snakes. A couple of species also use palm trees for the cavity site.
Birds in the
Picoides genus are mainly black and white. All three species have three toes, instead of the normal four that almost all other woodpeckers have. Two of the species live in northern North America, and the Eurasian three-toed woodpecker lives in northern Eurasia. They mainly eat beetle larvae, but also other insects, fruit, and some sap. Unlike most other woodpeckers, these species do not usually peck perpendicular to the tree to forage for insects. Instead they peck more laterally to dislodge the bark, not to make a hole in the tree. Whether this foraging method is a result of having only three toes is unknown.
The Sapsuckers of genus
Sphyrapicus are restricted to North America. The are medium sized woodpeckers with a length of 17 to33 cm. They feed mainly on the sap of trees which they tap by making small holes. A sapsucker's tongue is adapted with stiff hairs for collecting the sap. They visit the same tree multiple times drilling holes to cause the sap to flow. This may eventually kill the tree. The insects attracted to the sap are also consumed, and not only by sapsuckers. They excavate their nests in trees.
There is also one species in
Xiphidiopicus, the Cuban green woodpecker.
Of all the species described here only one does not have a conservation status of Least Concern. The red-cockaded woodpecker is listed as Near Threatened because it has breeding requirements that rely on large pine trees. Most of the other woodpeckers are more tolerant in their habitat requirements and can usually adapt to highly degraded woodlands.
