The
bird family Petroicidae includes roughly 45 species in about 15 genera. All are endemic to
Australasia: New Guinea, Australia, New Zealand and numerous Pacific Islands as far east as
Samoa. For want of an accurate common name, the family is often called the
Australasian robins. Within the family the species are known not only as robins but as scrub-robins and flycatchers. They are, however, only distantly related to the
Old World family
Muscicapidae (to which other species with such names belong) and the
monarch flycatchers (Monarchidae).
