The Australian bird famous for mimicking other birds and chainsaws is the lyrebird.
Lyrebirds are ground-dwelling Australian songbirds, especially known for the superb lyrebird. Their elaborate vocal performances combine their own calls with remarkably accurate imitations of sounds heard in their surroundings. Researchers have recorded them copying many native bird calls, along with noises such as chainsaws, car alarms, camera shutters, dogs barking, and human voices.
The mimicry is learned rather than completely innate. A lyrebird can absorb sounds from neighboring birds and from human activity, which explains why different populations may have different repertoires. In Tasmania, some superb lyrebirds have retained calls belonging to species that are not native to the island, apparently preserving sounds learned from earlier generations.
Males use extended vocal displays during courtship, sometimes singing for as much as four hours a day during the June-to-August breeding peak. A common mix-up is assuming only males mimic: females can also produce complex mimetic vocalizations, particularly while foraging or defending a nest.
