List Of Piciformes By Population
This is a list of Piciformes species by global population. While numbers are estimates, they have been made by the experts in their fields. For more information on how these estimates were ascertained, see Wikipedia's articles on population biology and population ecology. This list is not comprehensive, as not all Piciformes have had their numbers quantified.

Nine families of largely arboreal birds make up the order Piciformes , the best-known of them being the Picidae, which includes the woodpeckers and close relatives. The Piciformes contain about 71 living genera with a little over 450 species, of which the Picidae (woodpeckers and relatives) make up about half. In general, the Piciformes are insectivorous, although the barbets and toucans mostly eat fruit and the honeyguides are unique among birds in being able to digest beeswax (although insects make up the bulk of their diet). Nearly all Piciformes have parrot-like zygodactyl feet—two toes forward and two back, an arrangement that has obvious advantages for birds that spend much of their time on tree trunks. An exception are a few species of three-toed woodpeckers. The jacamars aside, Piciformes do not have down feathers at any age, only true feathers. They range in size from the rufous piculet at 8 centimetres in length, and weighing 7 grams, to the toco toucan, at ...
