}} The brown-backed woodpecker (Dendropicos obsoletus) is a species of bird in the family Picidae. It has a wide distribution in tropical Africa where its range extends from Senegal in the west to Ethiopia, Kenya and Tanzania in the east. This species is described as generally uncommon, but it has a very large range and the population appears to be steady, so the International Union for Conservation of Nature has rated its conservation status as being of "least concern".[1] DescriptionThe brown-backed woodpecker is a small species, growing to a length of between {{convert|13|and|16|cm|in|1|abbr=on}}. The beak is long and chisel-tipped with a wide base. The male has a red hind crown and nape while the female lacks these. Otherwise the sexes are similar, the head is brown with a white supercilium and moustache and dark ear coverts. The body plumage is brown with white barring on the wings and tail and the underparts are whitish, with variable amounts of dark streaking. When the feathers are worn, this bird looks rather pale and can be confused with the little grey woodpecker (Dendropicos elachus).[2] Distribution and habitatIt is native to Benin, Burkina Faso, Cameroon, Central African Republic, Chad, Democratic Republic of the Congo, Eritrea, Ethiopia, Gambia, Ghana, Guinea, Guinea-Bissau, Ivory Coast, Kenya, Mali, Mauritania, Niger, Nigeria, Senegal, Sierra Leone, Sudan, Tanzania, Togo, and Uganda.[1] It inhabits open, dry areas, scrubland, the edges of woodland, especially Combretum woodland and Hagenia forest, savannah with scattered trees and suburban gardens. Its altitudinal range is from sea level to about {{convert|2300|m|ft|-2|abbr=on}}, and even higher on Mount Kenya.[2] References1. ^1 2 {{IUCN|id=22681030 |title=Dendropicos obsoletus |assessor=BirdLife International |assessor-link=BirdLife International |version=2013.2 |year=2012 |accessdate=26 November 2013}} {{Taxonbar|from=Q27074900}}{{DEFAULTSORT:woodpecker, brown-backed}}2. ^1 {{cite book|author1=Hans Winkler|author2=David A.
