Birds Do It

Don't know about the bees. (For those who may be too young to understand this allusion: There's an old Cole Porter song that goes, "Birds do it, bees do it, even educated fleas do it; let's do it, let's fall in love.")
   We know that many species of birds have altered their songs to be heard above human-made ambient noise. Some have also come to mimic some of the sounds they hear around them. A new study has found that grasshoppers, too, are changing their tune so that they can hear each other: http://www.sciencedaily.com/releases/2012/11/121113214935.htm
