Tiny Australian bird cries wolf to scare predators
One of Australia\'s smallest birds has found a cunning way to protect its nest from predators by crying wolf, or rather hawk, and mimicking the warning calls of other birds. Researchers from the Australian National University (ANU) found that the tiny brown thornbill mimics the hawk warning call of a variety of birds to scare off predators threatening its nest, such as the larger pied currawong.
Sydney: One of Australia's smallest birds has found a cunning way to protect its nest from predators by crying wolf, or rather hawk, and mimicking the warning calls of other birds. Researchers from the Australian National University (ANU) found that the tiny brown thornbill mimics the hawk warning call of a variety of birds to scare off predators threatening its nest, such as the larger pied currawong.
"It is not superbly accurate mimicry but it is enough to fool the predator," said Branislav Igic in a university statement.A physical attack on a currawong would be no good. They are 40 times the size of a thornbill and will eat adults as well as nestlings. This study is the first to show that birds use vocal mimicry to scare predators.
