Domestic Creole ducks (PCDs) are hardy, less nutritionally demanding, less susceptible to disease, and promising among native species due to their rapid growth rate. In Guatemala, PCDs are part of the biological heritage of people who live in rural areas. The present study aimed to characterize the backyard PCDs to identify the morphometry for their selection, conservation and use. The work was carried out in the municipalities of Camotán, Chiquimula; San Manuel Chaparrón, Jalapa and Olintepeque, Quetzaltenango. With a sample of 376 PCD, adults, females and males from the families' backyard for convenience. The zoom variables were 17 for the female, 14 for the male, and eight zoom indexes. A univariate analysis was performed, determining arithmetic means, standard deviations, coefficients of variation and standard error, and multivariate between populations. The results indicate that the morphometry describes a bird that has an elongated and narrow head, more body length than a dorsal elevation, an elongated and elliptical trunk, raised in front because the dorsal elevation is greater, thoracic perimeter is greater and curved, back flat and elongated rump in females (p˂ .0001). Long, elongated, light weight and strong long hindquarters. These local genetic resources or ecotypes are the product of local environmental conditions, accepting that it is a Cairina moschata domestica, Donkin 1989 or Muscovy in Guatemala.
