Conservation Status:  

 

 

This species is listed as Endangered in the IUCN Red List of Threatened Species (https://www.iucnredlist.org/).


According to the IUCN Red List Assessment, the population of this species is declining, with the current population  estimate of 800-1,200 individuals. The threat to its persistence comes from habitat disturbance due to large-scale agriculture and other human encroachments. Indian species are threatened by the garbage dumps that may have harmful pollutants. Accidental ingestion of polythene bags from the garbage dumps is also a major threat to this species (BirdLife International 2016).
