As an example of sexual dimorphism, the male Mockery Birds have a large hump on their beak, while the females have only a small, bony shield. The bird was named after its call, that sounds like laughter (much like the kookaburra's).
This example illustrates the concept of sexual dimorphism in Mockery Birds, highlighting the distinct physical characteristics between males and females. The species' name originates from its distinctive vocalization, which shares similarities with human laughter.
