A recent report in The Age has described some research by Dominique Potvin, Kirsten Parris and Raoul Mulder on how the songs of urban silvereyes are different from those of their country cousins. They call more slowly, at a higher pitch, and use different notes.
This research is part of Dominique’s recently-completed PhD on how urban noise affects song learning, development and evolution in silvereyes. Her studies on this species have taken her across Australia and onto numerous Pacific islands.
