A preliminary survey of bird species and habitat in the Karmajhiri Range, Pench Tiger Reserve was conducted during March 2014 - May 2014. The aim of this study was assessment of avian population by addressing some ecological status such as faunal type, phenological traits, trophic status, occurence and protection status of birds species. 221 species of birds were recorded from study area. Out of 26 order in India 16 order of birds were presented in and around Pench Tiger Reserve (PTR) which comprises 61 families. PTR provides habitat for three critically endangered species, namely White-rumped Vulture (Gyps bengalensis Gmelin, 1788), Red-headed Vulture (Sarcogyps calvus Scopoli, 1786) and Indian Vulture (Gyps indicus Scopoli, 1786). Regarding species protected by Berne convention 34 species are listed in Appendix 2 (strickly protected fauna) and only one are represented in Appendix 3 (Protected fauna) House Sparrow (Passer domesticus Linnaeus, 1758). Based on the AEWA (African-Europian Migratory Waterbird Agreement) bird list, 18 bird species are noted in the study area. The dominance of Oriental faunal type provide information on the relationship of the surveyed avifauna to the biogeographical zones. We were recorded 28 biome restricted bird species.  This assessment also supports and justifies its classification as an Important Bird Area “IBA” because of the importance and abundance of avian species. Its provide shelter and hosts to birds. To conserve birds species in tropical deciduous forest in PTR, it will be necessary to preserve large areas of contiguous forest and monitor the effect of Habitat fragmentation and other development activities in and around forest area will have impact on their foraging, breeding and subsequently their population. These scientific findings will help to evaluate the effectiveness of legislation and policies for bird protection and will under in future conservation action for birds and their habitats.

Alternative Drugs

Three endemic vulture species Gyps bengalensis , Gyps indicus and Gyps tenuirostris are critically endangered following dramatic declines in South Asia resulting from exposure to diclofenac, a veterinary drug present in the livestock carcasses that they scavenge. Diclofenac is widely used globally and could present a risk to Gyps species from other regions. In this study, we test the toxicity of diclofenac to a Eurasian ( Gyps fulvus ) and an African ( Gyps africanus ) species, neither of which is threatened. A dose of 0.8 mg kg −1 of diclofenac was highly toxic to both species, indicating that they are at least as sensitive to diclofenac as G. bengalensis , for which we estimate an LD 50 of 0.1–0.2 mg kg −1 . We suggest that diclofenac is likely to be toxic to all eight Gyps species, and that G. africanus , which is phylogenetically close to G. bengalensis , would be a suitable surrogate for the safety testing of alternative drugs to diclofenac.

Population Ratio

Chhattisgarh is home to seven of the nine vulture species in India. One reason for this high vulture diversity is the presence of large herds of bovines numbering over 11 million individuals (ratio of human to bovine population is approximately 0.38), from which carcasses are disposed off in the open for scavengers. The late 1990s saw large scale decimation of vulture population, and since then there have been few studies with no sighting estimates available.  In this study, concurrent sighting records were collected from different locations of southern Chhattisgarh and corroborated to develop conservative sighting estimates for sympatric populations of Gyps bengalensis and Gyps indicus. We present the first report on population recovery, with an estimated 30–35 Gyps bengalensis & 20–25 Gyps indicus in/ around Rudraram of Bijapur and 18 Gyps bengalensis & five Gyps indicus at Jamguda village of Bastar. Krishna Swami Gutta hill is identified as a nesting-roosting habitat for both species, for which six scavenging areas were identified in Bastar and Bijapur districts. The human/bovine population ratio for Bastar is 0.4, similar to the state ratio, while in Bijapur the ratio is 1.07, which justifies considering Bijapur as a conservation refuge. The few vultures that survived the diclofenac catastrophe in wild habitats most likely consumed wildlife carcasses that sustained a residual population. In these areas, the age-old practise of disposing off dead domesticated bovines away from settlements near reserve forests may also have supported the recovery of vulture population.

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.

The Impact

SummaryThe Critically Endangered Oriental White-backed Vulture Gyps bengalensis has declined across most of its range by over 95% since the mid-1990s. The primary cause of the decline and an ongoing threat is the ingestion by vultures of livestock carcasses containing residues of non-steroidal anti-inflammatory drugs, principally diclofenac. Recent surveys in Pakistan during 2010 and 2011 revealed very few vultures or nests, particularly of White-backed Vultures. From 2011 in the Tharparkar District of Sindh Province we monitored a colony of Oriental White-backed Vultures. Between 2011 and 2014 the number of active nests in this colony increased from 11 to 34 while nest density decreased from 13.7 to 9.2 nests km-2, suggesting that the colony is expanding. We conclude that the rate of increase is being subsidised by immigration, as the population demographics do not support the observed rate of increase in nests. We present the first analysis of spatial breeding dynamics for the Oriental White-backed Vulture and describe how a clustered pattern of nest trees in colonies supports a highly clustered pattern of nests. The spatial pattern of nests relies on both the distribution of trees and the ability of trees to support more than one nest. These results highlight that the preservation of larger nest trees and the sustainable management of timber resources are essential components for the conservation management of this species. We emphasise the high importance of this colony and a nearby Long-billed Vulture Gyps indicus colony in this area of Pakistan. Recommended conservation management actions include the continuation of a Vulture Safe Zone established in 2012, measuring breeding success, assessing dispersal and determining the impact of mortality on these populations.
