This page contains the sound files of the Pijanowski et al. (2011) BioScience article titled "Soundscape Ecology: The Science of Sound in the Landscape."

Sound Files:

Sound file 1. Dawn chorus at La Selva Biological Research Station in Costa Rica. Recordings made on April 12, 1989 at 05:45 local time.

Sound files 2-4. Recordings taken in the Mediterranean Maqui (a scrubland habitat), Italy, illustrating the potential impact of the song of a non-endemic species in songs of two endemic birds.

Sound file 5. Urban noise taken at a busy intersection in Tippecanoe County near the Purdue University campus. Sounds include automobile traffic, motorcycle (passing at 56 seconds), computerized carillon bells from Purdue's Heavilon Tower (playing Purdue's fight song and the alma mater) and the call of nighthawks approximately every 2.5 seconds. Recording taken June 23, 2009 at 10:00 PM local time.

Sound file 6. A dawn chorus recording in a tropical rain forest in Madagascar in 1996. See text for details.

Sound file 7. Nighttime recording of forest elephants trumpeting around a bai. Also present are night time sounds of crickets and frogs. See text for details.

Sound file 8. Dawn chorus recording of a dry forest in Zimbabwe, the first 1:12 seconds of this recording reflect complex rhythmic sounds produced by birds and other organisms. Starting at 1:13, baboons begin to bark, using the surrounding rock outcrops to propagate their calls. Note the large differences in echos between the baboons (more than 4 seconds) and those of the birds (less than a second).

Sound file 9. Microphone placed over an ant colony. Note the complex sounds created by the stridulating insects.

Sound file 10. Ambient sounds in the Algonquin National Park in Ontario, Canada, are quickly replaced by the howls of gray wolves. These soundmark vocalizations characterize the north woods ecosystems.

Sound files 11-34. One-minute recordings started at the top of every hour for one day (April 20, 2008) in our Tippecanoe Rhythms of Nature Study wetland site (Purdue Wildlife Area).

Sound files 35-38. Four dawn chorus recordings from the Sequoia National Park study. All were taken on May 11, 2002, each close to 0500 hrs. Temperature at all sites but Crescent Meadow was 12 °C. Crescent Meadow was -3 °C.
