The lyrebird, most commonly found in Australia, is capable of mimicking an extraordinary range of sounds while singing to attract a mate. But as the below clip with David Attenborough demonstrates, humans aren’t always aware of the considerable impact they have upon nature. As reported in 2001 by the Register and in 2005 by the Hindustan Times, birds have also picked up an uncanny ability to impersonate ringtones. But perhaps the saddest part of this story is the possibility put forth by the National Audubon Society last year: noise pollution may be causing birds to lose their capacity to sing.
