Open pit mining leads to impacts on ecosystems and their biotic, abiotic and social components, leaving semi-arid areas for prolonged periods of time. This study carried out an inventory in order to understand the diversity and richness of birds at three sites: Belencito, Chámeza and Malsitio (Boyacá, Colombia), where open-pit mining is practiced in order to extract limestone. The samples were obtained from September 2018 to January 2019, and in each location an area of 1000 m2 and nine observation points with a distance of 500 m between each point were established. 50 species of birds were identified, including some migratory and endemic species. In Belencito the highest alpha diversity was recorded (q0 = 42 and q1 = 26.6 species), while in Chámeza the lowest diversity was recorded (q0 = 17 and q1 = 11.87 species).
