Human activities have been influenced the biotic and abiotic factors of the ecosystem, causing air pollution, degradation of ecosystems and water contamination. The emission of pollutants from the air, mainly by the intense traffic of vehicles and the industries, generate alterations in the morphology, physiology and behavior of several animals. The birds respond to these environmental changes and present quantitative information on the qualitative aspects of the environment, being used as biomonitoring. One of the tools for biomonitoring is the analysis of erythrocyte nuclear abnormalities, among which the number of enucleated erythrocytes, called erythroplastids stands out, and several studies relate their presence with air pollution. Thus, the objectives of this study were to quantify the presence of erythroplastids in Antilophia galeata, to relate the presence of these cells with the distance of the studied areas of the urban environment, and to verify if the presence of erythroplastids is related to the body condition and seasonality. Capture campaigns were carried out between June 2013 and October 2018 in five Cerrado areas in the Triângulo Mineiro; blood extensions were made and measurements were taken to calculate the body condition of the birds. The analysis of erythroplastids was made by optical microscope and 10 thousand erythrocytes were counted per individual analyzed. There were a difference in the amount of erythroplastids among the areas: within the urban environment and with intense flow of vehicles in their proximity versus areas more distant from the urban environment and with a high degree of preservation. No relationship was found between the presence of erythroplastids and the body condition and between the dry and rainy seasons. The quantification of erythroplastids in A. galeata can be considered a biomonitoring tool of the air quality.'
