They have a large, straight bill with a distinctive hook at the end which is used to skewer prey. They have high-pitched complex songs, which are used to defend their essentially year-round group territories: unlike birds of extratropical Eurasia and the Americas, both sexes sing prolifically.

Biology
They are
insect eaters for the most part, but will also feed on small lizards and other vertebrates. They get their name from their habit of impaling captured prey on a thorn, tree fork, or crevice. This "larder" is used to support the victim while it is being eaten, to store prey for later consumption, or to attract mates.
They are the ecological counterparts of the

urbanisation and can be found in leafy suburbs throughout Australia. They are opportunistic, showing little fear and readily taking food offerings to the point of becoming

They tend to trail behind their mother and "squeak" incessantly while she catches food for them.
