BIRDLIFE CHARACTERIZATION IN FIVE COASTAL WETLANDS OF SAN ANTONIO PROVINCE

Abstract

Coastal wetlands are considered one of the most productive systems in the world, where birds are a showy component and the presence of some species can be useful for making decisions about their conservation. We sought to characterize the birdlife of five coastal wetlands in order to find differences between lagoon and estuary birds. For the above, we proceeded to the analysis of our own and eBird data of the last ten years (2008 - 2018) of the Albufera, Llolleo, Cartagena, El Peral and Río Maipo estuaries, of the San Antonio Province, Valparaíso Region. The results show that the Río Maipo estuary is the area with the highest number of resident bird species in danger of extinction, including the presence of exotic species. Taxocenosis reveals that there is a high similarity between all coastal wetlands (Ij> 0.5). It is considered necessary to complement the present work with a biocenosis analysis. The Llolleo Lagoon is the most risky wetland, due to the construction of the large-scale port of San Antonio that is projected after 2020, which will be located adjacent to the Maipo River Wetland.
