Variable Chachalaca

About the Variable Chachalaca

The little chachalaca (Ortalis motmot) is a bird in the family Cracidae, the chachalacas, guans, and curassows. It is found in Brazil, French Guiana, Suriname, Guyana, Venezuela and possibly Colombia. In 1760 the French zoologist Mathurin Jacques Brisson included a description of the little chachalaca in his Ornithologie based on a specimen collected in French Guiana. He used the French name Le faisan de la Guiane and the Latin Phasianus guianensis. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added 240 species that had been previously described by Brisson. One of these was the little chachalaca. Linnaeus included a brief description, coined the binomial name Phasianus motmot and cited Brisson's work. The specific name had been used by the Dutch zoologist Albertus Seba in 1734 when he had misapplied the Aztec name motmot to a chachalaca. The species is now placed in the genus Ortalis that was introduced by the German naturalist Blasius... Wikipedia →
