The golden-headed quetzal (''Pharomachrus auriceps)'' is a strikingly coloured bird in the genus ''Pharomachrus''; it is also referred to as ''Trogon auriceps''. It is found in moist mid-elevation forests from eastern Panama to northern Bolivia. The golden-headed quetzal is known for its iridescent green colour, which it shares with other quetzals, and its distinctive golden head. The female of the species is less brightly coloured, displaying more brown tones than the male. The golden-headed quetzal’s diet consists mainly of fruit, and occasionally insects. It is generally a solitary and quiet bird unless it is breeding season, when the male and female become a monogamous pair and create a cavity nest in an old tree. During breeding season both sexes share brooding and feeding duties for 25–30 days until the chick is ready to fledge. The golden-headed quetzal is fairly common and considered a species of least concern. == Taxonomy == The golden-headed quetzal was first described by John Gould in the 2nd edition of ''A Monograph of the Trogonidae or family of Trogons'' published in 1875.〔Henry Sotheran Limited, fine books and prints (). Henry Sotheran Limited; (2015 Oct 17 ). Available from:http://www.sotherans.co.uk/Prints/gould/trogons_toucans.php〕 It is one of five birds in the genus ''Pharomachrus,'' known as quetzals, and is included in the family Trogonidae, which is made up of birds found in tropical rainforests worldwide.〔Collar NJ. 2001. Order Trogoniformes. In: del Hoyo J, Elliot A, Sargatal J, editors. Handbook of the Birds of the World. Vol 6. Barcelona: Lynx Edicions. p. 80-127.〕 The word quetzal comes from the Nahuatl (or Aztec) word ''quetzalli'' (from the root ''quetz'' meaning "stand"), which translates to "long green plume" or "tail feather of the quetzal".〔Bierhorst J. 1985. A Nahuatl-English dictionary and concordance to the cantares mexicanos. California: Stanford University Press.〕 Quetzal is usually specifically used to refer to the resplendent quetzal (''Pharomachrus mocinno'') first described by Pablo de la Llave in 1832 but in reality it applies to all members of the genera ''Pharomachrus'' and ''Euptilotis''.〔Quetzal. 1890. In: Encyclopedia Britannica a dictionary of arts, sciences, and general literature. Chicago: R. S. Peale & Co. p. 179-180.〕 ''Pharomachrus'', coined by Pablo de la Llave, stems from Ancient Greek ''pharos'' meaning "mantle" or "cloak" and ''makros'' meaning "long" in reference to the impressive tail of the resplendent quetzal.〔Gotch AF. 1981. Birds: their Latin names explained. Blanford Press.〕 Two subspecies are recognized, ''P. a. auriceps'' (Gould, 1842) and ''P. a. hargitti'' (Oustalet, 1891).〔Integrated taxonomic information system (). (2015 Oct 17 ). Available from: http://www.itis.gov/servlet/SingleRpt/SingleRpt?search_topic=TSN&search_value=554487#〕 The species name, ''auriceps'', comes from Latin ''aurum'' meaning "gold" and ''ceps'' meaning "crowned" or "headed", in reference to the golden head of ''Pharomachrus auriceps.''〔Peru birds ().
