Inventory of birds in two urban wetlands in Temuco (Chile): a basis for monitoring species

Inventario de aves en dos humedales urbanos de Temuco (Chile): una base para el monitoreo de especies

Abstract:

In the city of Temuco, Chile, the importance of urban wetlands has been recognized with the legal declaration of two key ecosystems: Humedal Vegas de Chivilcán and Humedales de Antumalén. This paper presents an inventory of birds in these wetlands, following the Darwin Core standard, and compares the results with other selected inventories in Chile. Observations were made using point counts and 21-hour transects. A total of 50 species from 26 families and 15 orders were identified, with a predominance of native species. Fourteen species were found in both wetlands, 20 exclusively in Chivilcán and 15 in Antumalén. Comparison with other studies revealed significant differences in bird composition between urban and peri-urban habitats, illustrating that urban habitats maintain a unique diversity distinct from that of peri-urban areas. The diversity of habitats and the ‘least concern’ status of most species highlight the importance of these wetlands as refuges for avian biodiversity. The structure of the Darwin Core database facilitates their integration with other biodiversity systems, highlighting the need for continued conservation and study of these urban ecosystems.
