Resplendent quetzal

The resplendent quetzal ( /ˈkɛtsəl/) (Pharomachrus mocinno) is a bird in the trogon family. It is found from Chiapas, Mexico to western Panama (unlike the other quetzals of the genus Pharomachrus, which are found in South America and eastern Panama). It is well known for its colorful plumage. There are two subspecies, P. m. mocinno and P. m. costaricensis. The resplendent quetzal plays an important role in various types of Mesoamerican mythology. It is the national bird of Guatemala, and its image is found on the country's flag and coat of arms. It also lends its name to the country's currency, the Guatemalan quetzal (abbreviation GTQ). The resplendent quetzal was first described by Mexican naturalist Pablo de La Llave in 1832. It is one of five species of the genus Pharomachrus known as quetzals. The term 'quetzal' was originally used for just this species, but is now applied to all members of the genera Pharomachrus and Euptilotis. Two subspecies are recognised, P. m. mocinno and P. m. costaricensis. The epithet mocinno is Llave's Latinization of the name of the biologist J. M. Mociño, a mentor of his. (It is sometimes spelled mocino, but 'ñ' was formerly spelled 'nn' in Spanish, so the spelling with 'nn' is justified and in any case now official.) The word 'quetzal' came from Nahuatl (Aztec), where quetzalli (from the root quetza = 'stand') meant 'tall upstanding plume' and then 'quetzal tail feather'; from that Nahuatl quetzaltotōtl means 'quetzal-feather bird' and thus 'quetzal'. This species is 36 to 40 cm (14–16 in) long, plus up to 65 cm (26 in) of tail streamer for the male, and weighs about 210 g (7.4 oz). It is the largest representative of the trogon order. The subspecies costaricensis is slightly smaller than the nominate race, with tail plumes that are both shorter and narrower. Resplendent quetzals have a green body (showing iridescence from green-gold to blue-violet) and red breast. Depending on the light, quetzal feathers can shine in a variant of colors: green, cobalt, lime, yellow, to ultramarine. Their green upper tail coverts hide their tails and in breeding males are particularly splendid, being longer than the rest of the body. Though quetzal plumages appear green, they are actually brown due to the melanin pigment. The primary wing coverts are also unusually long and give a fringed appearance. The male has a helmet-like crest. The bill, which is partly covered by green filamentous feathers, is yellow in mature males and black in females. Their iridescent feathers, which causes them to appear shiny and green like the canopy leaves, are a camouflage adaptation to hide within the canopy during rainy weather. The skin of the quetzal is very thin and easily torn, so it has evolved thick plumage to protect its skin. Like other members of the trogon family, it has large eyes that adapt easily to the dim light of its forest home.
