Abstract
La identificación de aves y principales amenazas de los humedales es importante ya que la avifauna cumple un rol ecológico clave en todos los ecosistemas, sin embargo, es la línea investigativa que menos se desarrolla o en muchos casos está incompleta. La finalidad de este proyecto de investigación fue identificar la riqueza total de avifauna del Humedal Urbano Escuadrón-Laguna Quiñenco que se ubica en la comuna de Coronel, Región del Biobío. Se realizaron 10 recorridos generales, a lo largo del año 2023, por la ribera de la laguna, más tres visitas nocturnas, cada recorrido fue de aproximadamente cuatro horas, identificando las especies en forma visual y/o auditiva utilizando aplicaciones especializada en el reconocimiento de avifauna. Se identificó un total de 52 especies, las cuales son 25 especies más de las que se pudieron revisar en estudios anteriores, Durante los recorridos generales de muestreo se registró también las principales amenazas para el humedal, entre estas se encuentran los clásicos microbasurales y perros asilvestrados. Establecer esta línea base es crucial para futuras investigaciones, en las que se concentren en un estudio holístico donde se reconozca a las aves como especies claves y fundamentales en la conservación del ecosistema estudiado, y no en cambio, centrarse solo en la flora o fauna mayor, que si bien son importantes no se pueden estudiar de manera aislada al buscar acciones efectivas y eficaces de conservación.
The identification of birds and main threats to wetlands is important since avifauna plays a key ecological role across ecosystems. However, it is least developed research line or, in many cases, it is incomplete. The purpose of this research project was to identify the total bird richness of the Escuadrón-Laguna Quiñenco urban wetland located in Coronel, Biobío Region. Ten general surveys were conducted throughout the year 2023 along the lakeshore, along with three nocturnal visits, each survey lasted approximately four hours, identifying species visually and/or by their calls using specialized bird recognition applications. A total of 51 species were identified, 25 more than those reviewed in previous studies. During the general sampling surveys, the main threats to the wetland were also recorded, including the classic micro-landfills and feral dogs. Establishing this baseline is crucial for future research focusing on a holistic study recognizing birds as key and fundamental species in the conservation of the studied ecosystem, rather than solely focusing on the flora or larger fauna, although they are important, they cannot be studied in isolation when looking for effective and efficient conservation actions.
