Distribution and habitat

The Conondale ranges in Queensland's 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. An Estimate of the Plumed Frogmouth ''Podargus ocellatus plumiferus'' Population Size in the Conondale Ranges WW Document URL http://search.informit.com.au/documentSummary;dn=668756953042077;res=IELNZC (accessed 4.16.14). The species roosts in the canopy of and is considered cryptic and extremely hard to find or study. Current populations are threatened by land clearing, inappropriate fire regimes and timber harvesting with future impacts of climate change posing additional risks. 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.

Behavior

''P. ocellatus'' is a nocturnal ground feeder. During the day, it sleeps on a tree branch with its beak pointing upward, taking on the appearance of a tree branch. To cope with the heat and humidity of its tropical home, ''P. ocellatus'' has heart and respiration rates lower than is typical for birds of its size. During periods of

, it will enact panting as a cooling mechanism, with more efficient cooling effect than is seen in other bird species performing the same action.
