Abstract:

This report summarizes the 2008–2011 field seasons for the Highway 71 impact assessment of ; highway construction noise and activity on golden-cheeked warblers (Setophaga chrysoparia). Researchers ; examined if construction activity and noise altered the reproductive success and behavior of birds, with an ; emphasis on the golden-cheeked warbler. ; Researchers found that ambient noise levels were significantly higher in 2011 than 2010 across study ; sites, and decreased significantly as distance from ROW increased. Ambient noise levels were louder 512 m ; from the ROW in the construction site when compared to levels at 256 m and 512 m in the pre-construction ; site. Pairing success was significantly lower in the control site in 2010 than any other site and year ; combinations. Fledging success was significantly lower in 2009 than in other years, across all study sites. ; There was no indication that birds directly reacted to construction noise or that they altered their ; singing or nesting behavior. Researchers found no effect from study site, distance from the ROW, or year on ; w arbler reactions to construction noise playbacks.
