Abstract
In approximately the last thirty years the U.S. population has increased by one third, while aircraft traffic has increased by three fold. Research has shown that road traffic noise causes birds to shift their song upwards in frequency. It is unknown if non-overlapping, lower frequency aircraft noise alters bird vocalizations. To test this we placed recorders in a natural area under the flight path of airplanes arriving and departing Jacksons Hole Airport in Grand Teton National Park. Here we present the results of our bioacoustics analysis of Black-capped Chickadee (Poecile atricapillus) song properties (song frequency, bandwidth and duration) in the presence of airplane noise and in quiet background sound conditions.
