Geographic Range [top]
Range Description: Rhizothera longirostris occurs in the Sundaic lowlands of south Tenasserim, Myanmar, peninsular Thailand, East (Sabah) and Peninsular Malaysia, Singapore, Brunei, and Kalimantan and Sumatra, Indonesia, where it is generally uncommon, (BirdLife International 2001). No population estimates are available, but it is thought to be declining rapidly owing to habitat loss and degradation.
Countries occurrence:
Native:
Indonesia; Malaysia; Myanmar; Thailand
Additional data:

Population [top]
Population: The population size of this species has not been quantified; according to del Hoyo et al. (1994) it is never widely encountered.
Trend Justification: There are no data on population trends; however, logging and hunting are suspected to be causing a moderately rapid decline in this species.
Current Population Trend: Decreasing
Additional data:
? Number of mature individuals: Unknown ? Continuing decline of mature individuals: Unknown
? Extreme fluctuations: No ? Population severely fragmented: No
? Continuing decline in subpopulations: Unknown
? Extreme fluctuations in subpopulations: No ? All individuals in one subpopulation: No
Habitat and Ecology [top]
Habitat and Ecology: It inhabits primary and old secondary lowland and hill forest and bamboo, up to 1,500 m in some regions, although not above 1,000 in others (BirdLife International 2001). It can persist in tiny forest fragments, but conversely is apparently absent from many large areas of apparently suitable habitat (D. L. Yong in litt. 2013).
Systems: Terrestrial
Continuing decline in area, extent and/or quality of habitat: Yes
Generation Length (years): 3.9
Movement patterns: Not a Migrant
Threats [top]
Major Threat(s): Forest destruction in the Sundaic lowlands of Indonesia and Malaysia has been extensive (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), and declines are compounded by trapping for the cage-bird industry (BirdLife International 2001). However, the speciess use of secondary growth and higher elevations implies that it is not immediately threatened.
Conservation Actions [top]
Conservation Actions: Conservation and research actions underway
It occurs in a number of protected areas, including Taman Negara National Park and Gunung Leuser National Park.
Conservation and research actions proposed
Survey to assess the population size. Protect large areas of primary and old secondary forest within its range. Investigate the taxonomic status of the race dulitensis.
