Australia's lyrebird can copy chainsaws, camera shutters and car alarms

the gist

Lyrebirds are two species of ground-dwelling Australian birds in the genus Menura, famous for mimicry. They can imitate other birds, and also artificial sounds from their surroundings. The male's huge tail, shaped like an ancient lyre when fanned out, is used in courtship displays. Males sing and dance on display mounds on the forest floor, with the mimicked sounds forming part of the performance. Lyrebirds are among Australia's best-known native birds and are notable for their plain-coloured but striking plumes.

how it works

Birds produce song with a syrinx, a voice organ at the base of the windpipe with two sides. Lyrebirds have unusually complex syrinx muscles and learn sounds by hearing them, so they can reproduce whatever they hear often.

so what

Mimicry lets a male show how many sounds he has mastered, which females may use to judge quality. Lyrebirds also preserve sounds: some mimic songs of other species that can be heard in their territory.

fun fact

The bird is named for the lyre, an ancient stringed instrument, whose shape the male's fanned tail resembles.
