Birds are bioindicator species, with continuous monitoring of their community important to assess the degree of changes in the environment. This study aimed to compare the composition and structure of the bird community in three different environments: fields, woods and urban area of the central campus of UFRN. Between 2016 and 2017, 56 species of birds were registered through 81 Mackinnon lists, 44 of which occurred in the fields, 36 in the urban area and 33 in the forest. Most of them are common and of low sensitivity to anthropic alterations, mainly including omnivorous and insectivorous species, being Coereba flaveola and Pitangus sulphuratus the most frequent in all environments. There was a high similarity between the avifauna of the three environments and also between the bird communities of Parque das Dunas and Campus, where 54% of the species were common to both. It is likely that the intense urbanization of the campus has contributed to the population decline or even the local extinction of bird species more sensitive to changes in the landscape. On the other hand, synanthropic and more generalist species increased their densities. It is assumed that they use the countryside environment mainly as a resting and foraging point, because in this occurred greater wealth. The population of Athene cunicularia depends exclusively on this environment to survive, just as the forest species Ortalis araucuan, Hemitriccus griseipectus and Cantorchilus longirostris depend on the maintenance of the forests.
