This species has been uplisted to Near Threatened owing to evidence that is has undergone a moderately rapid population decline over the past three generations.

Behaviour It is resident where is occurs, but has vast home ranges, and juveniles will wander even more widely than adults (Ferguson-Lees and Christie 2001). Habitat The species occupies remote, mountainous areas, with precipitous terrain, usually above 1,000 m, and in particular areas where large predators such as wolves and Golden Eagles are present, and there are herds of mammals such as mountain goats, ibex, and sheep (Ferguson-Lees and Christie 2001). Diet The species will forage over vast distances (up to 700 km in one day has been recorded), using a soaring flight. Its principle food is carrion, with its diet including a large proportion of bones (as much as 85%) whereupon the bird gets nutrition from the marrow inside. The rest of its diet comprises tortoises, and occasionally also live mammals and birds. It is generally unwilling to compete with vultures at carcasses, and will wait patiently to feed, scavenging older carcasses if fresh meat is scarce. Bones are either consumed whole, broken using the bill, hammered against the ground, or lifted into the air and dropped from 50-80 m high onto hard rock. Tortoises and hyraxes are generally treated in the same way as bones. It is known to scavenge in rubbish dumps, including urban areas in Ethiopia (Ferguson-Lees and Christie 2001). Breeding Site The species will construct large nests (averaging 1-m diameter), composed of branches and lined with animal remains such as skin and wool, as well as dung and occasionally also rubbish. Nests are located on remote overhung cliff ledges or in caves and will be re-used over the years. Breeding occurs from December to September in Europe and northern Africa; October-May in Ethiopia; May-January in southern Africa; year-round in much of eastern Africa; and December-June in India (Ferguson-Lees and Christie 2001).
The main causes of on-going declines appear to be non-target poisoning, direct persecution, habitat degradation, disturbance of breeding birds, inadequate food availability, changes in livestock-rearing practices and collisions with powerlines and wind turbines (Ferguson-Lees and Christie 2001, Barov and Derhé 2011, S. Xirouchaki in litt. 2012). Despite the provision of targeted conservation actions, the European population remains susceptible to poisoning and mortality caused by powerlines (J. A. Gil Gallus in litt. 2011).
In South Asia, the most significant potential threat may be from diclofenac, a non-steroidal anti-inflammatory drug (NSAID) used in livestock and responsible for catastrophic declines in three of the region's Gyps species since the 1990s, through ingestion at contaminated carcasses and resultant kidney failure (reviewed by Das et al. 2010). Gypaetus barbatus is primarily a bone-eater, and it is not known if diclofenac residues remain within bones of treated animals, although residues are known to be passed into feathers and hair; however, the local collapse in Gyps species could allow this species to access and feed on soft tissues from which it would have been excluded (C. Inskipp and H. S. Baral in litt. 2013).
In the Himalayas of India, the species may be impacted by the increase in feral dogs, which potentially compete for food (P. Trivedi in litt. 2013). Rapid increases in grazing pressure and human populations in the mountains of Iran, Afghanistan, Iraq, Turkey and western Pakistan are causing habitat degradation in these countries (S. Viter in litt. 2014). Suitable habitat is also threatened by pipeline construction through the Altai and Caucasus mountains, and powerline construction is planned from Tajikistan through Afghanistan to Pakistan and India (S. Viter in litt. 2014). In parts of Nepal at least, the species may suffer from the collection of nestlings, as they are seen by local people as a good omen for prosperity, as well as the destruction of nests to reclaim human-made materials such as rope and fabrics, and hunting pressure driven by the use of the species's intestines in tradit
Conservation Actions Underway
In Europe, captive breeding and reintroduction programmes have been carried out in the Austrian, French, Italian and Swiss Alps with individuals subsequently spreading into other parts of France (Snow and Perrins 1998, Frey and Walter 1989). Reintroduction programmes are underway in parts of Spain (J. A. Gil Gallus in litt. 2011). Feeding stations have been provided in the Pyrenees with resulting increases in numbers of the species, and the provision of similar stations across the species's range could improve its global population density (Ferguson-Lees and Christie 2001). A reintroduction programme was attempted in Kenya in 1999-2003 (S. Thomsett in litt. 2011).
Conservation Actions Proposed
Conduct coordinated surveys to monitor the species's global population trend. Assess the threat posed by diclofenac and other drugs used in livestock, as well as the impacts of climate change and feral dogs. Reduce disturbance in and around nesting areas. Mitigate against the impacts of wind turbines and powerlines. Combat the threat of persecution through laws and awareness-raising activities. Provide feeding stations throughout the species's range.
