Caracterização da avifauna em quatro fragmentos de áreas verdes urbanas de Juiz de Fora (MG)

Abstract

Birds can be considered bioindicators of the places where they live. For this reason, it is important to have records on the diversity of the avifauna of a given location, especially urban green areas, in order to know the conservation status of these areas. With this in mind, the aims of this research are to characterize the avifauna, in a comparative way, in four urban green fragments in the city of Juiz de Fora, regarding feeding guilds, taxonomic composition and species richness, and to update the city's species list, which resulted in 353 species. To do this, we used the list of species of four urban green areas, the list from the WikiAves platform and data related to the food guild categories of each species, the conservation status was used according to the IUCN and a Jaccard index was drawn up to compare the species composition of the areas. The four most abundant families in the four areas have a diverse diet and most of them are small, with a generalist diet. The distribution of feeding guilds in all the areas analyzed is very similar. However, the taxonomic composition of the species and the relationship with the number of families found in the four areas are different, especially when looking at the avifauna of Mariano Procópio, which is different from the others. The size of the area available to the avifauna also influences the diversity of the area. Richness increases as the green area available also increases.
