Why and how do birds sing? How can sound help you identify them?  We’ll touch on these questions and more as we explore the fascinating language of birds, with an emphasis on local species. This hour-long program will include an introduction to sonagrams (visual representations of bird vocalizations) and examples of how to listen to, describe, and learn bird vocalizations. Aimed at a general audience; all skill levels welcome. Presented by Eric & Joanna Reuter (contact Eric with any questions). Adults & teens.
