Class 5, September 23:

 

Animal sound production.

 

Learning outcomes:

 

  • You will compare and contrast different animal sound production mechanisms and observe and record real animals that are using these mechanisms on our field trip to the Cornell Plantations.

 

  • You will use the animal identification key method to deduce the identity of an animal using its vocalization, both in your pre-lecture assignment and during our field trip.

 

 

Assignment:

 

Start this one early, it may take you a little while:

 

  • Read the last part of Bradbury and Vehrencamp chapter two (pages 33-51, scan below).

 

 

 

  • Watch the video below (https://youtu.be/h0omB48ePMA).

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

  • Listen to the audio track linked below. When you listen to the sounds, you will hear that each has a number. Each student will be assigned a number that corresponds to one sound made by an animal that you can hear in Ithaca.

 

Your task is to use any resource you have available (excluding Dr. Dowling) to determine what animal is making the sound. I suggest making a spectrogram of your sound in Raven as the first step. Here are a few resources that will help: animal sound website list. The Piazza thought questions will help you to narrow down the possibilities. Answer these questions in Piazza 4 (https://piazza.com/cornell/fall2015/bionb4200/home):
