Soundbites is a (hopefully) weekly feature of the coolest, newest bioacoustics, soundscape, and acoustic research, in bite-size form. Plus other cool stuff having to do with sound. We’re back after a two-week hiatus that allowed our students to finish the term successfully!
Robins sing from higher perches when near roads: road noise impacts many species (see Danielle’s masters project), and there has been a lot of work done on birds. However, it’s rarely done to this fine of a spatial scale. The authors speculate that sitting at higher perches allows male robins to hear their rivals better.
“I ain’t been dropping no eaves, sir, honest!”: if you’ll forgive the blatant Lord of the Rings reference, what I’m really trying to say is that eavesdropping is important. These researchers agree. Across the board, eavesdropping on other species’ alarm calls has fitness consequences.
Harbor porpoises change behavior in response to seismic survey noise: while previous studies showed no difference in behavior, this study finds that certain vocalizations are less likely to occur when seismic survey noise is present.
Fun link of the week: not animal-related, but soundscape-related. What does Brazil sound like when they score in the World Cup? Listen to this recording of a neighborhood in last week’s match against Croatia.
