The study was conducted to investigate the phenotypic diversity of Guajolote present in small backyard poultry operations. From September 2004 to July 2006, in 54 municipalities in the coastal region of Oaxaca, Mexico 768 “guajalotes” growers were visited. Eleven different phenotypes of Guajolote, previously described as turkey varieties, have been identified. The phenotypes identified and their frequency are: Bronze (30.1%), Black (29.0%), Royal Palm (13.4%), Auburn (5.3%), Bourbon Red (5.2%), Narragancet (2.6%), Spotted (2.4%), Brown (2.2%), Slate (1.7%), White (1.5%) and Imperfect Albino (0.2%). The remainder (6.4%) were not identified as a phenotype previously described. This is the first report about the phenotypic differentiation of Guajolote in Mexico.
