The marbled frogmouth (''Podargus ocellatus'') is a species of bird in the Podargidae family. It is found in Australia, Indonesia, Papua New Guinea, and Solomon Islands. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. There are five subspecies recognised; the nominate ''ocellatus'' is found in New Guinea and surrounding islands. Two subspecies are found on islands of Papua New Guinea; ''intermedius'' is found on Trobriand Islands and D'Entrecasteaux Islands, ''meeki'' is endemic to Tagula Island. Australia has two subspecies; ''marmoratus'' is found on Cape York Peninsula, ''plumiferus'' (known locally as the 'plumed frogmouth') is found in SE Queensland.〔http://www.planetofbirds.com/caprimulgiformes-podargidae-marbled-frogmouth-podargus-ocellatus〕〔http://www.environment.gov.au/biodiversity/threatened/publications/action/birds2000/pubs/plumed-frogmouth.pdf〕 The Conondale ranges in Queenslands Sunshine Coast is considered a stronghold for the plumed frogmouth; notable populations are within the Conondale National Park. The species is rare and is listed as vulnerable in Queensland and occurs in subtropical rainforest and vineforest at altitudes from 50-800 m.〔Smith, G.C., Hamley, B.J., Lees, N., 1998.

Current populations are threatened by land clearing, inappropriate fire regimes and timber harvesting with future impacts of climate change posing additional risks.〔Smith, G.C., Hamley, B.J., 2009. Variation in vocal response of Plumed Frogmouth (Podargus ocellatus plumiferus) to call-playback. Emu 109, 339–343.〕 There have been estimates of the current pairs in the Conondale ranges being around 800 pairs with the current range of the species is just under 2000 ha with some potential future habitat increase in population being created by regenerating rainforest previously logged. Its specialised habitat requirements being un-logged pristine forests, the species is considered extremely vulnerable due to significant habitat reduction.〔 Future harvesting of native timber in the Conondale region also poses risk.〔 ''Rigidipenna inexpectatus'', endemic to four islands in the Solomon Islands, was formerly considered a subspecies. It was split into its own genus, ''Rigidipenna'', in 2007.〔Cleere et al. 2007.
