Birds are constrained to use a relatively narrow frequency bandwidth when they communicate vocally. Dense vegetation as well as natural sounds produced by insects like cicadas have the potential to interfere with bird communication. Similarly, anthropogenic noise from helicopters and may impact the frequency and time during which birds may most effectively signal. We are actively evaluating these ideas with the use of songmeters in both Costa Rica and Hawaii. Please see the “publications” section of this website for links to relevant manuscripts, including:
