The biotic and abiotic characteristics of the different types of habitats that make up a landscape can have important effects on the presence,abundance and density of animal populations. However, the structure of the landscape can be modified as a result of anthropic activity. TheYungas are one of the most threatened environments, parrots being one of the most affected groups in this region. In this work we evaluateif the structure of the landscape influences the presence and abundance of parrot species in the Yungas of Jujuy. The work was carried outin the Premontane Forest for two years (2014-2016). Observations of abundance of parrots were carried out at 71 count points. Thestructure of the landscape was characterized by geographic information systems. A Redundancy analysis was performed to analyze theresponse of the species to the composition of the landscape. A total of 3186 parrot specimens were observed (x = 4.95 individuals). Pionusmaximiliani was the most abundant species (n = 1250), followed by Amazonas aestiva (n = 862) and Pyrrhura molinae (n = 628). Forestcoverage is positively related to the presence and abundance of the total parrot ensemble. Generalist species were more abundant in citruscrops, and sugarcane and soya crops affected most species negatively. In agrosystems, the presence of species is positively related to forestwindbreaks. The results emphasize the need to conserve forests, and in agrosystems we recommend keeping the forest windbreaks for thesustainability of the populations
