Say what?

Scientists have found that Killer whales off the US West Coast have significantly lengthened their calls to one another in the past few years. Why might that be? Because of all the noise generated by the engines of whale watching boats hounding them in a near constant flotilla.

Similarly, male nightingale's mating songs have spiked 14 decibels making them louder than a chainsaw. Why? to compete with the sounds of the city of course.

Animals are autoplastic. They adapt to our ways. Do they judge us? Are they offended by our audacity? Do they even begin to understand? Who knows? In general, I think we can say that animals are pretty cool customers - they roll with us without complaint.
