Resumen
Cerro páramo de Miraflores (CPM) is one of the high mountain ecosystems with a high degree of conservation located further south of the eastern cordillera. This research represents the first approach to the diversity of birds of this moor that has been historically affected by the armed conflict, a situation that added to its difficult access has hindered the knowledge of its biodiversity. In this sense, this work aims to determine the composition and structure of the assembly of birds in the high andean and subparram strip of the CPM, located between the departments of Huila and Caquetá, by means of the sighting methodology in transect without estimated distance and capture by middle of fog nets. 407 individuals, 53 species, 47 genera and 19 families were registered, of which Thraupidae, Tyrannidae and Trochilidae were the most representative families. In addition, the presence of two national and globally threatened species, 11 species threatened by illegal trade, eight almost endemic species and four species with new distribution records is highlighted. The high andean strip had a greater diversity of birds (H ’= 3,192) with respect to the subparum area (H’ = 2,559), in addition, they presented a significant exchange of species. These results show the good state of conservation and highlight the ecological importance of this area, which favors the high diversity of species and trophic groups of the species through the altitudinal gradient, so it is essential to establish management, conservation and monitoring plans of the birdlife present at the CPM.
