Chestnut Woodpecker

The chestnut woodpecker (Celeus elegans) a species of bird in subfamily Picinae of the woodpecker family Picidae. It is found on Trinidad and in every mainland South American country except Argentina, Chile, Paraguay, and Uruguay. == Taxonomy and systematics == The chestnut woodpecker has these six subspecies: C. e. hellmayri Berlepsch, 1908 C. e. deltanus Phelps, W.H. & Phelps, W.H. Jr., 1950 C. e. leotaudi Hellmayr, 1906 C. e. elegans (Müller, P.L.S. 1776) C. e. citreopygius Sclater, P.L. & Salvin, 1867 C. e. jumanus (Spix, 1824) Some studies have found that subspecies citreopygius and jumanus are more closely related to the blond-crested woodpecker (C. flavescens) than to the other chestnut woodpecker subspecies. They have at times been treated as one or two separate species, and their exact placement is not fully resolved. Several more subspecies have been proposed as divisions of the six, but all have been determined to be either indistinguishable from one of the six, an aberrant form of one of them, or a hybrid. == Description == The chestnut woodpecker is about 26 to 32 cm (10 to 13 in) long. Subspecies C. e. hellmayri weighs 138 to 168 g (4.9 to 5.9 oz), C. e. leotaudi…
