| description | Worldwide, urbanization impacts biodiversity, causing animals and plants to adapt, disappear, or be exposed to new conditions. This research evaluated the effect of noise and vegetation cover on bird diversity in urban green spaces. This was done in the southern area of the city of Loja. Point counts were used to study birds in 7 green spaces; noise (dBA) and vegetation cover (richness, abundance, basal area, canopy density and tree height) were measured. Generalized linear mixed models (GLMm) with Poisson distribution adjustment were performed to analyze the relationships between variables and identify the one with the most significant effect on bird species richness and abundance. As for the results, 333 birds were recorded, where the most abundant species were Zenaida auriculata (65), Furnarius cinnamomeus (42) and Columba livia (41). The highest number of richness was in the Reinaldo Espinosa Botanical Garden (14 species), while abundance was higher in Parque Central, representing 21% of birds recorded. The urban green spaces with the highest noise levels were Parque los Molinos (68.77-75.43 dBA) and Parque Simón Bolívar (69.67-78.20 dBA). Noise and vegetation cover did not influence the richness and abundance of urban birds, even though canopy density and tree species richness were the most significant predictors of bird diversity. Consequently, the study concludes that birds adapt to the urban environment, which makes the number of species more homogeneous among the different areas, with between 11 and 14 bird species recorded in the study, although this range of diversity could decrease in the future. Keywords: bird diversity, urban green spaces, generalized linear model, noise, urbanization. |

En esta investigación se evaluó el efecto del ruido y la cobertura vegetal sobre la diversidad de aves presentes en los espacios verdes urbanos en la zona sur de la ciudad de Loja. Se utilizaron puntos de conteo para estudiar aves en 7 espacios verdes; y se midió ruido (dBA) y cobertura vegetal (riqueza, abundancia, área basal, densidad de la copa y altura de los árboles). Se realizaron modelos lineales generalizados mixtos (GLMm) con ajuste de distribución de Poisson para analizar las relaciones entre variables e identificar la de mayor efecto significativo en la riqueza y abundancia de especies de aves. En cuanto a los resultados, se registraron 333 aves, donde las especies más abundantes fueron Zenaida auriculata (65), Furnarius cinnamomeus (42) y Columba livia (41). El mayor número de riqueza fue en el Jardín Botánico Reinaldo Espinosa (14 especies), en cambio, la abundancia fue mayor en Parque Central, representando el 21% de aves registradas. Los espacios verdes urbanos con mayor nivel de ruido fueron Parque los Molinos (68,77-75,43 dBA) y Parque Simón Bolívar (69,67-78,20 dBA). Pese a que los resultados mostraron que la densidad de la copa y la riqueza de especies arbóreas eran los mejores predictores para la diversidad de aves, el ruido y la cobertura vegetal no influyeron sobre la riqueza y abundancia de las aves urbanas, de esta manera, los resultados contradicen las suposiciones. Con lo que se concluye que existe un tipo de adaptación de las aves al medio urbano, haciéndose más homogéneo el número de especies, entre las diferentes áreas, donde se puede registrar la presencia de entre 11 a 14 especies de aves en el estudio, pero que dicho rango de riqueza en un fututo podría reducirse.
