Agricultural environments contribute to bird biodiversity and birdwatching in rural landscapes
摘要
Brazilian natural landscapes are recognized as maintaining high biodiversity. Moreover, anthropogenic ecosystems can also contribute to society achieving sustainable development objectives, promoting the sustainable use of ecosystems and halting biodiversity loss. In this context, we analyzed the presence of bird species in six rural environments to support dialogue on environmental conservation and rural tourism. We observed 127 species, of which, 46 species were recorded in both open and forested environments. The greatest species richness was verified in the environments of Open/Agricultural (69 species) and Forest/Riparian (57 species). Species residing in the Rio Grande do Sul and summer residents predominated over summer visiting (such as Mycteria americana and Petrochelidon pyrrhonota). Xanthopsar flavus, considered threatened with extinction for Rio Grande do Sul, Brazil, and globally by the International Union for Conservation of Nature (IUCN), was observed on a single occasion in the Open/Agricultural environment. In ordering the environments, forests differed from open environments, partially due to food sources (diets), the presence of isolated trees (perches), and places for shelter and breeding. Our results suggest that maintaining heterogeneous habitats on rural areas supports a high richness of bird species, contributing to bird biodiversity in agricultural environments. This diversity of birds may be part of environmental education actions and provide cultural ecosystem services, especially bird watching associated with rural ecotourism.
