The sole representative of the genus
Clytoceyx, the Shovel-billed Kookaburra is endemic
to New Guinea
. It primarily occurs in hill forests, but has been recorded from sea-level up to an altitude of 2400 m (7850 ft). It finds its food in mud or on moist ground. The diet consists mainly of earthworms, snails, beetles, lizards and insects. It is inconspicuous and infrequently seen. It is likely that it is partially crepuscular
.
Widespread but uncommon throughout a large part of New Guinea, the Shovel-billed Kookaburra is evaluated as Least Concern
on the IUCN Red List
of Threatened Species.
