This simple lab provides sound clips (wav files) of silver perch, spotted seatrout, and red drum chorusing aggregations recorded in the May River estuary, SC.

• Save the three sound (wave) files of silver perch, spotted seatrout, and red drum on your computer.

• Download Audacity free software to PC or Mac: https://www.audacityteam.org/download/

• Open each wave file in Audacity, play the sound clip, and review the corresponding spectrogram.

• Answer the following questions for each species: (i) what is the frequency range (Hz) of calling and chorusing observed in the spectrogram; and (ii) can you differentiate individual calls among the chorus?

• Grading rubric: (i) completion and accuracy – 60 points at 10 points/question; (ii) writing – 30 points; (iii) format – 10 points
