The behaviour of birds to settle or rest at a place at specific times of day and night is called roosting. Some birds prefer solitary roosting while others roost communally. The Communal roosting behaviour of Egyptian vulture was studied in five districts (Sambhal, Lakhimpur Kheri, Aligarh, Bareilly and Faizabad) of Uttar Pradesh, India from January 2014- December 2017. Total count was conducted at roosting sites in all the seasons (summer, winter and monsoon). The maximum number of individuals counted at the roost site was in Sambhal followed by Lakhimpur Kheri, Aligarh, Bareilly, Faizabad. Four different roost substrates were identified: Ground, tree, building, and electric pylon. A maximum (63%) of Egyptian vultures were observed roosting on the ground, followed by electric pylon (19%), tree (10%) and minimum on building (8%). The present study confirmed that Egyptian vultures are communal roosters and a number of roosting individuals most probably depended on the availability of food of the area. Egyptian vultures are globally endangered species and so far no work has been done on their roosting behaviour in India; therefore the present study will prove beneficial to plan for their conservation strategies.

Demographic Evolution

SummaryThe Egyptian Vulture Neophron percnopterus is a threatened species throughout its worldwide range. The Iberian Peninsula holds 50% of its global population, which has declined by 25% over the last 20 years. Despite this negative global trend, an increase in the number of individuals over the last 25 years has been observed in Catalonia, where it has colonised areas in which it was previously unknown. In this study, we describe the demographic evolution of an increasing population of Egyptian Vultures in central and eastern Catalonia and we apply population models and maximum likelihood procedures to investigate both the main demographic processes driving the observed trends and the viability of the population. The number of pairs in this region increased from one to 22 in the period 1988–2012. The best-supported models suggest that adult survival in this population may be higher than in other Iberian populations and that furthermore, there is a continuous influx of immigrants. Based on the most likely scenarios, Population Viability Analysis predicts that the population will continue to increase. Sensitivity analysis indicates that the adult survival rate has the greatest influence on population dynamics so conservation efforts will be more effective if concentrated on improving this rate.

AbstractIdentifying threats to declining species and prescribing ways of preventing their extinction are basic challenges for biodiversity conservation. We analysed the causes underlying the loss of territories of the Endangered Egyptian vulture Neophron percnopterus in a key population at the north-western edge of its distribution in Europe by developing multi-scale models that combined factors from nest site to landscape. We used generalized linear models and an information-theoretic approach to identify the optimal combination of scales and resolutions that could explain territorial abandonment. Those models combining nest-site and landscape scales considerably improved prediction ability compared to those considering only one scale. The best combined model had a high predictive ability (96.9% of correctly classified cases). Small cliffs at high altitudes in rugged areas with declining livestock (especially of sheep and goats) increased the likelihood of territory abandonment. Our findings highlight the importance of developing region-specific multi-scale models to determine reliably the factors driving territory loss and of designing effective conservation strategies accordingly. Conservation measures for the studied population should be developed at two spatial scales. At the smaller scale it is necessary to closely control nest sites to avoid direct disturbances. At a larger scale it is essential to implement policies that can support traditional pastoralism.

SUMMARYBhadawari buffaloes are reputed for high milk fat and are found in the Agra & Etawah districts of Uttar Pradesh and the Bhind & Morena districts of Madhya Pradesh. Information on the status, management practices, morphological characteristics, body measurements and performance of the Bhadawari breed were recorded from its breeding tract. Animals true to the breed are copper in colour and have a white ring on the lower side of the neck. The population of this breed is declining at a fast pace and efforts are needed for its conservation. Strategies for its improvement and conservation are also discussed.

The Egyptian Vulture Neophron percnopterus is a globally endangered species that is experiencing rapid population declines throughout most of its range. Conservation of Egyptian Vultures in Africa is globally important because it holds a resident population of 1 000 – 2 000 breeding pairs, harbours a significant but unknown number of Eurasian migrants during the boreal winter, and many non-adult Egyptian Vultures reared in Eurasia dwell in Africa until they mature. Africa comprises approximately half of the area of the global range of the species. Once considered common and widespread in many parts of Africa, Egyptian Vulture is now one of the vulture species that is most threatened with extinction. Egyptian Vulture is considered extinct as a breeding species in Southern Africa, and continuous population declines have been reported from most of its African range, resulting in a population reduction of perhaps 75%. Despite these declines, there is an apparent lack of systematic observations, and its current status in many African countries is unknown. Furthermore, little is known about the magnitude of the various threats and their impact on resident and wintering Egyptian Vultures. Data-deficiency hinders conservation efforts across the continent. We conducted an extensive review of published and unpublished information on the resident Egyptian Vulture populations in Africa, in an attempt to systemize the available knowledge of the species’ historic and current occurrence on a country-by country basis and identify the threats it faces. Information was found from 39 countries; no records of Egyptian Vultures were found in 16 other countries. In 12 countries where Egyptian Vultures have been observed, breeding has never been confirmed, and observations most likely refer to vagrants or wintering individuals. The Horn of Africa appears to be a relative stronghold, but there too, losses almost certainly have occurred. Poisoning, electrocution and direct killing for belief-based practices are considered the main mortality factors, and are hampering the species’ recovery. The review highlights the dire status of Egyptian Vultures in Africa, and calls for the urgent implementation of various large-scale conservation measures that will combat threats, secure the survival of the species on the continent, and make Africa safer for migrants coming from Eurasia.
