Native to central and eastern Australia , the superb lyrebird is a famously gifted impressionist , and is one of nature ’s keen examples of mimicry . In the wild , the birds regularly copy the songs of other coinage as well as other forest fathom , though they normally watch their sonic repertoire from older lyrebirds rather than straight parroting the noise in their surroundings .
Captive lyrebirds have also been bed to base their calls around anthropogenetic sounds , withcamera shutter and chainsawsbeing among the most challenging recorded examples . A celebrated lyrebird namedChook , for example , is said to have developed an impressive array of power tool sounds after witnessing the construction of a new coon bear enclosure at Adelaide Zoo .
Leanne Golebiowski , the unit supervisor for bird at Taronga Zoo , toldThe Guardianthat Echo first start imitating the cry of a baby last year . “ In a zoological garden gear up , because there is such an teemingness of sound that they would get wind , it would be operose for these fowl not to mime some of them , ” she enjoin .
“ I can only take on that he picked it up from our guest . ”

While both male and female lyrebird are known to imitate a wide array of strait , Male tend to be considerably more vocal , particularly during the breeding season . These borrowed calls are believe to play a role in courtship , although it is in all likelihood thatavian mimicryserves a multitude of intent , many of which are not yet translate .
In addition to their impressive library of impressions , lyrebirds do also produce their own born call , which has been described as “ mechanical ” and consists of a series of whirring , clicking and grinding sounds .
According to Golebiowski , lyrebirds tend to practice Modern sound before deciding whether or not to add them to their regular repertory . “ I ’m not too trusted what it is about the babe weep that [ Echo ] detect interesting or gripping , but I desire it wo n’t make the net cut , ” she tell .
