“…When these are fed upon by vultures then the drug is biomagnified. This biomagnification leads to death due to kidney dysfunction which ultimately leads to kidney failure (Ghalib et al, 2019).The production of veterinary Diclofenac is already banned in Nepal, Pakistan and India since 2006, but still, some illegal production and supply is being maintained in the market (Subedi and DeCandido, 2014).…”

Vultures are excellent indicators of environmental health and as carrion feeders play an important ecological role. They are the only known vertebrate obligate scavengers. Nine different species of old world vultures are found in India. Red-headed Vulture (RHV) is one of the resident vulture species and is found throughout the country up to 2000 m elevation. This study was carried out in two states of India, Uttar Pradesh and Madhya Pradesh known as Bundelkhand. The grids of 15x15 sq km and random points were laid over the study area. Transects of 10 km were conducted in all the selected grids. As a result, 46, 54 and 74 vultures were recorded from 2017 to 2019, respectively. There was a continuous rise in the RHV population during the study period, which is a good sign for the species. Along with other vulture species, RHV is also facing serious threats. Biotic and abiotic threats such as habitat loss, predation, hunting and disturbance, scarcity of food and water, change in land use and agricultural practices, poisoning and, mortality in road accidents while feeding. The population trend is showing positive signs but only regular monitoring and conservation activities will help in saving the species.

“…Egyptian vultures were recorded in all five districts surveyed. Red-headed vultures were recorded in four districts except Salyan [14]. The Ghachowk vulture restaurant, established during 2010, is located in a river valley in the foothills of the Himalayas about 15 km northeast of Pokhara.…”

This study was objectively carried out to estimate population of red-headed vulture; documentation of its diurnal behavior, issues related to declining its number. Anbu Khairini, Tanahu Nepal was selected as study site. Data were collected applying transects walk technique maintaining 150m width on both sides of road during December, February and March. The binocular was used to observe the diurnal behavior of the vulture and camera was used to capture their photographs. Scan sampling method was applied to collect behavior data systematically during day time for twelve hours. Collected data were analyzed using descriptive analysis and non parametric Chi-square test. There were two adults and one sub-adult Sarcogyps calvus at Anbu Khaireni area. Red-headed vulture spends its time about 44.

“…Large trees (Chhangani, 2007;Dhakal et al, 2014) provided predator avoidance, suitable microclimates (Campbell, 2015) and increased mobility (Wright et al, 1986) for vultures. Nest elevation included those of the White-backed (-rumped) vulture at 16.6 m (Chomba and M'Simuko, 2013), 8 m -28 m (Subedi andDeCandido, 2014), 14.8 m (Thakur andNarang, 2012), 18 to 36 m (Naoroji, 2006), above 21 m (Thompson et al, 1990) and25-30 m (Ramkrishnan et al, 2014). Other species were recorded in smaller trees (Mangifera indica, Acacia nilotica, Azadirachta indica, Prosopis cineraria) in other regions such as arid Rajasthan and Maharashtra (Chhangani, 2007;Kambale, 2011;Khatri, 2013).…”

Vultures, their population status and some ecological aspects in an Indian stronghold

2020

Indian vultures have important ecological and socio-economic functions and are increasingly studied, per their ecological role and recently, their catastrophic populations’ decline. However, there are few studies of vultures in central India, a vulture stronghold. The present paper examined the presence, distribution per landcover variation, roosting and nesting habits of vultures in this region. Both quantitative (total count) and qualitative (questionnaire survey) methods of research were applied. The hypotheses were that vulture presence is higher in forested areas, unaffected by agricultural development (excepting the Egyptian vulture); as well as that vultures are more likely to roost and nest in large trees and on cliffs in open landcover. Vulture species recorded in summer and winter counts were the Long-billed vulture (Gyps indicus, Scopoli, 1786), Egyptian vulture (Neophron percnopterus, Linnaeus, 1758), White-rumped vulture (Gyps bengalensis, Gmelin, 1788), Eurasian Griffon vulture (Gyps fulvus, Hablizl, 1783), Red-headed vulture (Sarcogyps calvus, Scopoli, 1786), Cinereous vulture (Aegypius monachus, Linnaeus, 1766) and Himalayan Griffon vulture (Gyps himalayensis, Hume, 1869). Their average total abundance was of 7,028 individuals, maximum being Long-billed vulture (3,351) and minimum being Cinereous vulture (39). Thematic maps documented distributions in different agroclimatic regions and ecozones. Orography and forest structure influenced vulture presence, but human disturbance did not. Vulture protection, food monitoring and human-induced disturbances are manageable with critical, informed and flexible policies. These findings contribute to monitoring and management planning for vulture conservation in Central India and elsewhere.
