The ferruginous partridge (Caloperdix oculeus) is a species of bird in the Phasianidae family. It belongs to the monotypical genus Caloperdix. It is found in Indonesia, Malaysia, Myanmar, and Thailand. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical moist lowland forests. It is threatened by habitat loss.
This species inhabits evergreen and semi-evergreen rainforests, including swampy areas, dry hill forest and secondary forest with sufficient bamboo. It has been recorded to 1,200 m.
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).
Declines driven by habitat loss and degradation are compounded by trapping for the cage-bird industry. However, the species's use of secondary growth and higher elevations implies that it is not immediately threatened.
