As increasingly more bird species are found to alter their vocalizations in the presence of anthropogenic noise, researchers are developing more detailed questions about the process by which this behavioral modification occurs. One of these questions focuses on the time scale over which these noise adjustments happen: Do birds in noisy areas only vary their vocalizations during specific noisy events, or do noise-disturbed birds always sing different songs than their undisturbed counterparts? Results of a recent study by collaborators from the University of Ottawa and the University of Windsor suggest that, in one species at least, the answer is “both.” read more
