Abstract
About 9800 species of birds belonging to the avians class now a day, many are being raised as pets or kept in captivity, a fact which raises the need for more knowledge of anatomical and physiological order in these animals. The evolving capacities of the digestive tract allow the survival of many populations of avians presents, which created their own niche according available food resources. The interest was conduct a comparative anatomical description of the digestive tract of avians of the Columbiforms order, with four specimens of birds, Zenaida auriculata, Columba Livia, Patagioenas picazuro, donated by IBAMA, Uberlândia / MG. In the Laboratório de Ensino e Pesquisa em Animais Silvestres (LAPAS) UFU, the birds were photographed and identified as to species and dissected for the purpose of obtaining information on topography, form and dimensions of the segments of the digestive tract. All the studied specimens have cecum and ingluvium, and the digestive tract showed little topographical variations.
