The information in this article corresponds to a compilation of data from scientific journals, ornithological collections and virtual libraries (xeno-song, eBird and Biomap), as well as our contributions during more than 15 years of studies in Tolima. Together, this information allows us to understand the diversity of birds in the region. In addition, this article includes data on localities and the altitudinal and geographical distribution of each species. The results indicate the presence of 800 bird species in Tolima, of which 24 are endemic, 69 are near-endemic and 82 are migratory. Furthermore, 42 species face some degree of threat, two are classified as having deficient data and four have been introduced. This list constitutes a reference for studies of birds of the Upper Magdalena Valley. It is a necessary tool for conservation plans in this region of the country.
