The red-headed vulture has started becoming more harder to come by as it is being hunted down. Places like Cambodia have put together special programs to help critically endangered vulture species. There has been evidenced compiled that showed hunters have started “ the use of poisons in hunting practices”,[Loveridge, Robin. “Poisoning Causing the Decline in South-East Asia’s Largest Vulture Population.” , 8 Mar. 2019, https://www.cambridge.org/core/journals/bird-conservation-international/article/poisoning-causing-the-decline-in-southeast-asias-largest-vulture-population ] which has led to the population analysis showing “that since 2010 populations of the White-rumped Vulture (''Gyps bengalensis'') and Red-headed Vulture (''Sarcogyps calvus'') have declined, while the Slender-billed Vulture (''Gyps tenuirostris'') may also have started to decline since 2013”.
