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.

Terrestrial Woodpeckers
Andean Flicker Image by Adam_Kumiszcza
Most of the terrestrial woodpeckers obtain a considerable amount of their food while on the ground. They mainly eat ants, termites, beetles and their larvae; some also eat fruit and seeds. The New World terrestrial woodpeckers belong to genus
Colpates. There are two sister genera in the Old World:
Picus and
Chrysophlegma. In fact, there used to be only a total of two terrestrial woodpecker genera,
Chrysophlegma was seperated from
Picus.
The
Colpates New World woodpeckers typically have a brown or green back and wings with black barring, and beige to yellowish underparts with black spotting or barring. There are usually colorful markings on the head. They range in size from the grey-crowned woodpecker with a length of 17 cm to many
Colpates species that are a little over 30 cm long. Many of these birds – particularly the northerly species – are more terrestrial than usual among woodpeckers. Some species, such as the crimson-mantled woodpecker, were formerly placed in the genus
Piculus but moved to Colpates based on DNA analysis. Note that this classification was not made because they acted like a terrestrial woodpecker which is reflected by having "woodpecker" as part of their name instead of "flicker". Some
Colpates species make their nest-holes only in earthen bankings, others make them only in trees, and some species use both approaches.
The
Picus Old World woodpeckers typically have green upperparts. They are about the same size as their New World counter parts: 25 to 35 cm in length. Of the 13 species, two forage mostly in trees and 3 forage mostly on the ground; the remaining species forage at both places. Every member of
Picus excavates its nest cavity in a tree. The three
Chrysophlegma species used to be in
Picus until DNA analysis indicated that they probably did not have a common ancestor. They all forage in trees, not on the ground. All of the species from these two genera are found in Asia; two of them are also found in Europe.
Each of the three genera that are described here have 1 species that is not listed as Least Concern. Perhaps the fact that most of the species are diverse and forage on trees as well as on the ground helps protected them.
