This paper examines the environmental impact of ambient noise generated by mineral aggregate extraction activities, with particular emphasis on a site located in Teleorman County, Romania. The study area, designated as the ROSPA0024 Olt-Danube Confluence site and part of the Natura 2000 ecological network, is recognized for its high ornithological value, providing habitat for several protected bird species. Extraction operations, primarily consisting of desilting activities along minor channels of the Olt River, were systematically monitored to assess their potential effects on local avifauna. The research documented temporary yet measurable behavioural modifications among key bird species during periods of elevated noise levels. These included alterations in feeding behaviour, nest abandonment, and increased flight responses. The findings underscore the vulnerability of protected bird populations to industrial noise and indicate that existing mitigation measures are inadequate. This study provides empirical evidence to support the integration of stricter temporal restrictions on extraction activities, particularly during critical breeding and migration periods, as part of a broader strategy to reconcile economic development with biodiversity conservation objectives.
