Conservation Status: CRITICALLY ENDANGERED
The Sumatran ground cuckoo is a large, terrestrial species of cuckoo that is endemic to Indonesia. This elusive species is found only in the island of Sumatra and its favored habitats include foothills as well as montane rainforests.
According to the IUCN Red List of Threatened Species, the total population of Sumatran ground cuckoos ranges only from 50 to 249 mature individuals, and it is expected to decrease even further; they are considered to be one of the 100 most endangered bird species in the world.
Most modern-day sightings have taken place in the Barisan Mountains in South Sumatra, beginning with the individual photographed in Bukit Barisan Selatan National Park in 1997. Five more sightings were reported in the immediate vicinity between 2007 and 2010. However, if not protected from threats such as deforestation and snaring, these vulnerable birds might never be seen in the wild anymore.
