ABSTRACT.Livestock production is being questioned for its greenhouse gas emissions. However, production systems influence multiple environmental variables and, in some cases, contribute to very valuable environmental services. This work summarizes information collected at 30 livestock production farms and four IN-IAs experimental fields allocated throughout the Uruguayan territory. A total of 231 bird species were recorded, 42 of them identified like priority conservation species. Of these species 10 are included in UICN lists and 19 in Uruguayan Red List. We conclude that livestock production system based on natural grasslands are very rich ecosystem in term of bird species. Traditional management provides suitable habitat for several priority conservation species. However, several species, mainly tall-grass dependents, need special management measures.
