A
quail-thrush is a
bird of the genus
Cinclosoma, which contains seven species. Quail-thrushes are in a different family from either
quails or
thrushes, but bear some superficial resemblance to them. The genus is found in
Australia and
New Guinea in a variety of habitats ranging from rainforest to deserts. The genus is closely related to the
jewel-babblers of New Guinea. Seven species were recognised in 2007. A molecular study published in 2015 by Gaynor Dolman and Leo Joseph resulted in the splitting of the chestnut-backed quail-thrush into the
chestnut quail-thrush of eastern Australia and the
copperback quail-thrush in the west.
