Abstract

Coastal areas have the largest human population, causing significant urbanization impacts on biodiversity. The coast of Buenos Aires province (Argentina) has touristic cities, which have shown significant growth during the last decades. Therefore, it is fundamental to analyze the effect of urbanization on bird communities. The aim of this study is to analyze the bird communities present in residential areas and implanted forests on coastal dunes in Cariló. Eight fixed radius point counts were carried out in each habitat between spring 2021 and summer 2022. Both habitat types had similar values of species richness, Shannon and Simpson diversity, and functional diversity. However, residential habitat showed higher abundance than the forest. Significant changes between habitats in species composition were found. The Tropical Parula (Setophaga pitiayumi) and the Rufous-collared Sparrow (Zonotrichia capensis) were more abundant in the forest, while the Chimango Caracara (Phalcoboenus chimango), the Monk Parakeet (Myiopsitta monacha) and the Picazuró Pigeon (Patagioenas picazuro) were more abundant in the residential habitat. The residential area had a greater abundance of birds feeding on the ground, the canopy and the air. The results obtained suggest that the urban expansion on implanted forests promotes bird compositional changes, favoring species typical of semi-open habitats and impairing species associated with high tree cover and unmanaged herbaceous vegetation.
