Acanthiza is a genus of
They are found primarily in
The habitat preferences of the group vary from dense forest to open saltbush and bluebush plains.
Acanthiza follow a very characteristic undulating path when flying. Their
The nest of the Acanthiza is a large dome-shaped construction, completely enclosed except for a side hole, just like that of the long-tailed tit; however Acanthiza adds to it an additional room whose function is unknown. It is somewhat similar to the Aegithalidae in combining long incubation periods with highly synchronous hatching.[4] This combination, normally impossible due to intense competition for food,[5] occurs because parents and (usually) helpers can organise food supply in such a manner that sibling competition for food is virtually absent.[6]
The number of eggs usually ranges from two to four, and the incubation period is around twenty days with laying intervals of two days. The length of an adult bird is 8 to 10 centimetres (3.1 to 3.9 in).
