| Omschrijving: | Urban ecosystems have a great variety of pollutants such as noise that affect the communication of species. There are few studies on this subject in urban areas of Costa Rica and our objective was to characterize the environmental noise and bird richness of the microbasin of the Bermudez River. Eight transects were established where bird richness and environmental noise were recorded through counting points along the microbasin. We recorded 171 species belonging to 41 families. Significant differences were found in the number of species per site in periurban (136 species) and urban (108 species) areas. Noise was lower in the periurban zone (45.4 dB) than in the urban zone (59.4 dB). Environmental noise could have negative effects on birds, and it is necessary to establish noise mitigation measures that benefit the conservation of urban and riparian ecosystems. |
