About

As an educator, Dr. Proppe strives for a relaxed, yet rigorous, approach to learning about the natural world. He promotes applied learning through hands-on activities and example driven presentations. He is most invigorated when teaching students while immersing them in the ecosystems they are studying! Perhaps, that is because it is here that the beauty of God’s Creation is most evident.

In his spare time he enjoys spending time outdoors with his wife Sarah, son Elliot, and daughter Grace. He does watch birds off the job too, recently adding the Atlantic puffin, roseate turn, and kirtland’s warbler to his life list! He also enjoys road and mountain biking, hiking, and backpacking. Past experiences include leading wilderness trips in the West and Midwest, teaching scuba diving in the Caribbean, and teaching environmental education along the West Coast.

Academic Interests

Dr. Proppe is interested in how animals respond to novel environments – especially those altered by human development. His research focuses primarily on the responses of songbirds to the increasing levels of anthropogenic (human caused) noise that overlaps their vocal signals. Since these overlapped signals are less detectable, he is investigating mechanisms that species employ to increase the effectiveness of their signals in areas of high noise. He is also examining the negative impacts of noise on species diversity and fitness, and searching for potential tools to mitigate these negative effects.

  • The Effects of Sound on Songbird Behavior and Management.
  • Conspecific Attraction: Are Birds Attracted to Their Own Species Songs?
