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.
