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.

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).

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 (
