Large Frogmouth

Assessment Information [top]

Justification:
This forest-dependent species is listed as Near Threatened because it is assumed to be undergoing a moderately rapid decline owing to the extensive loss of lowland forests from large areas of the Sundaic lowlands.

History:

2008	–	Near Threatened
2004	–	Near Threatened
1996	–	Data Deficient
1994	–	Data Deficient
1988	–	Near Threatened

Geographic Range [top]

Range Description:	Batrachostomus auritus occurs very sparsely in south peninsular Thailand; Sabah, Sarawak and Peninsular Malaysia; Kalimantan (including the Natuna and Labuan islands) and Sumatra, Indonesia, and Brunei. It is an elusive and poorly known species, but appears to be genuinely rare or uncommon and is almost certainly declining owing to the destruction of lowland forest.
Countries:	Native: Brunei Darussalam; Indonesia; Malaysia; Thailand

Population [top]

Population:	The global population size has not been quantified, but the species is described as extremely rare in Thailand, rare in Peninsular Malaysia and local and very uncommon in Borneo (Cleere 1998).
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	It occurs in lowland dipterocarp forest to at least 250 m, perhaps 1,000 m. A nest has been described from a branch fork c.4 m from the ground, from which a chick hatched in mid-March (Cheong and Li 2010).
Systems:	Terrestrial

Threats [top]

Major Threat(s):	Rates of forest loss in the Sundaic lowlands have been extremely rapid (Kalimantan lost nearly 25% of its evergreen forest during 1985-1997, and Sumatra lost almost 30% of its 1985 cover), because of a variety of factors, including the escalation of logging and land conversion, with deliberate targeting of all remaining stands of valuable timber including those inside protected areas, plus forest fires (particularly in 1997-1998).

Conservation Actions [top]

Conservation Actions:	Conservation Actions Underway It is known from a number of protected areas, including Taman Negara National Park in Peninsular Malaysia, Way Kambas National Park in Sumatra, and Danum Valley and Gn Mulu National Parks in Borneo (Cheong and Li 2010). Conservation Actions Proposed Protect areas of lowland forest within the species's range. Enforce restrictions on agricultural encroachment and logging within such protected areas. Estimate population trends by calculating rates of forest loss within its range using satellite imagery and remote sensing techniques.
