This species is rare. It inhabits lowland rainforests in India (mostly in West Bengal), Bhutan, Bangladesh, Myanmar, Cambodia, Vietnam, Malaysia, and Indonesia, from the sea level up to 2,560m. It mainly forages on fruits (BirdLife International 2018).
According to the IUCN Red List Assessment, the population of this species is declining and its current population size is unknown. The threat to its persistence comes from habitat disturbance due to agriculture and other human encroachments. Adult survival is low possibly due to hunting for meat and feather (BirdLife International 2018).

Biodiversity Atlas - India is a species-based bioinformatics platform that is voluntarily supported by numerous organisations such as the National Centre for Biological Sciences,
Indian Foundation for Butterflies, Diversity India, and Titli Trust. The platform is designed for aggregating, displaying and analysing biodiversity data from tropical developing countries and other biodiversity hotspots such as India. It is a distributed platform of stand-alone, taxon-specific, natural history websites that give ownership and recognition to contributing naturalists. It is used extensively for research as well as educational and outreach activities by professional and citizen scientists. The 'BioAtlasIndia' website family currently has the following members:
