This forest-associated species is listed as Near Threatened because it is assumed to have experienced moderately rapid declines owing to the extensive loss of lowland forests from large areas of South-East Asia. It is not considered more threatened because it can use secondary and edge habitats (BirdLife International 2001, Wells 2005).
Distribution and populationChloropsis cyanopogon
Sibley, C. G.; Monroe, B. L. 1990. Distribution and taxonomy of birds of the world. Yale University Press, New Haven, USA.
is restricted to the Sundaic lowlands, from south Tenasserim, Myanmar
, peninsular Thailand
(scarce), Sabah, Sarawak and Peninsular Malaysia
, Kalimantan (including Banggi Island) and Sumatra, Indonesia
, where it is generally fairly common in forest to 700 m. Population justification
The population size is unknown, but the species is described as common where habitat remains (del Hoyo et al. 2006).Trend justification
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). However, the population is suspected to have declined more slowly as the species can tolerate secondary habitats.Ecology
Canopy and high edge of lowland evergreen forest, including peat-swamp forest, mature and regenerating secondary forest, also fruiting trees and shrubs in clearings and high shade cover of plantations. It occurs up to 700 m in most of its range but occasionally to 1,100 m in Malaysia. Birds in breeding condition have been recorded in February-August. Threats
Forest destruction in the Sundaic lowlands of Indonesia, and in Thailand 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), but the species's ability to survive in second growth and forest edge implies that it is not immediately threatened. Conservation Actions Underway
None are known. 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.
