Audubon Afternoon: Bird Song and Background Noise Levels
Sunday, September 29, 2013
3:00 pm to 5:00 pm
National Wildlife Federation
1110 Wildlife Center Dr.
Reston, VA 20190
Dr. David Luther, an ornithologist at George Mason University, will talk about
his research examining how bird songs have evolved to stand out in the presence
of loud background noise, such as the cacophony of birds singing in the dawn
chorus in the Amazon rainforest, or the “noise pollution” of urban rush hour
traffic. He will discuss current studies at field sites from here inside the
Beltway, to San Francisco, to the Amazon basin.
