This comes from today's online The Australian;

"SCIENTISTS claim the loud hum of city traffic is causing a common Australian bird to change its tune.

"A recent study has found the little city-dwelling silvereye is singing more simply, slowly and at a higher pitch than its country cousins so its tweets can be heard above the urban drone.

"The University of Melbourne, which looked at the behaviour of the common songbird,  said the findings indicates evolutionary change in the city species."
