What is "callaeidae"

The small bird family Callaeidae (also named in some sources as Callaeatidae) is endemic to New Zealand. It contains three monotypic genera, with five species in the family. One, the huia, became extinct early in the 20th century.

The Callaeidae are often known as wattlebirds, a term that leads to confusion, as there are other, unrelated species with this same name, notably the large Australian wattlebirds of the family Meliphagidae, which are honeyeaters. For this reason New Zealand wattlebirds is the informal name for this family used by the scientific community. Equally confusingly, they are also sometimes known as wattled crows, even though they are not corvids and are only distantly related to crows.
