Soundbites is a weekly (biweekly, mostly) feature of the coolest, newest bioacoustics, soundscape, and acoustic research, in bite-size form. Plus other cool stuff having to do with sound.
Acoustic “sonic net” may deter invasive European starling communication: noise isn’t all bad. Sometimes it allows us to get rid of things we don’t want, like invasive species. Here researchers used a “sonic net” comprising of frequencies overlapping with starling communication frequencies over a feeding patch. Birds under the net didn’t respond to alarm calls, which is promising in using acoustics as a deterrent for this species.
Singing higher doesn’t guarantee success for urban birds: blame the surplus of bird literature on springtime, I guess. In the bioacoustics world we often talk about the seminal “Birds sing at a higher pitch in traffic noise” paper; here, the author of that paper addresses how that affects survivorship. Turns out there’s no correlation between success in an urban environment and singing at a higher pitch.
Traffic noise masks communication in freshwater stream fish: I’m just going to leave this one here. Traffic noise can impact entire watersheds. Anyone interested in making quieter cars yet???
Fun link of the week: in the grand tradition of fun links of the week having nothing to do with sound, this one goes out to Selene, who defends on Friday. Good luck, Selene! You’re going to do awesome! (and clearly, bring a sword.)
