“…Cliff-breeding species often congregate with up to almost one thousand pairs in a colony in the Cape Griffon Gyps coprotheres in southern Africa (Mundy et al 1992) or more than a hundred pairs in the Eurasian Griffon G. fulvus in southern Europe (Slotta-Bachmayr et al 2005). In tree-breeding species, colonial breeding is unusual but found for example in White-rumped Vulture Gyps bengalensis in Asia (Thakur 2015). White-backed Vultures are widespread in sub-Saharan Africa and nest exclusively in large trees throughout their range.…”

“…In India, white-rumped vultures use chir pine (Pinus roxburghii) for nesting in Himanchal Pradesh (Thakur, 2015), coconut palm (Cocos nucifera), mango (Magnifera species) and Termenalia in Western Maharashtra (Majgaonkar et al, 2018), and white murdah (T. arjua) in Tamilnadu (Ramakrishnan et al, 2014). It appears that white-rumped vultures preferred certain trees irrespective of the diversity and availability of other trees.…”

“…In Nepal, three out of nine vulture species, namely red‐headed vulture ( Sarcogyps calvus ), slender‐billed vulture ( Gyps tenuirostris ), and white‐rumped vulture ( G. bengalensis ) are typically tree nesters while the Egyptian vulture ( Neophron percnopterus ) builds nests on trees on rare occasions (Ali & Ripley, 1987 ; Chhangani, 2002 ). These species require mature and tall trees for nesting (Ahmad et al., 2020 ; Ghimire et al., 2019 ; Majgaonkar et al., 2018 ; Siders & Kennedy, 1996 ; Thakur, 2015 ). The wild vulture population has been declining in South Asia due to the use of diclofenac in veterinary practices (Ahmad et al., 2020 ; Chaudhary et al., 2012 ; Khan, 2013 ; Prakash et al., 2007 ), food shortage (Shah et al., 2019 ), unintentional poisoning (Clements et al., 2013 ), human persecution (Clements et al., 2013 ; Hla et al., 2011 ), collision with power lines and electrocution (Hamal et al., 2023 ), and breeding habitat loss (Gautam & Baral, 2013 ; Hla et al., 2011 ).…”

White‐rumped vultures (Gyps bengalensis) are critically endangered species, and protecting their habitats, particularly the nesting trees, may have a positive impact on their reproductive success. For a better understanding of vultures' habitat needs, the characteristics of nesting trees should be accounted. In this paper, we compare the characteristics of the trees that have vultures' nests and that do not by randomly select a control tree within a 10 m radius of the nesting tree. We extensively searched and monitored the white‐rumped vultures' nests, nesting trees, and nesting tree species in Nepal between 2002 and 2022, and measured the characteristics of sampled trees such as their height, girth, canopy spread, branching orders, and whorls. We recorded 1161 nests of white‐rumped vulture in total on 194 trees belonging to 19 species over the past two decades. White‐rumped vultures preferred the kapok trees (Bombax ceiba) for nest construction than other tree species (χ2 = 115.38, df = 1, p < .001) as 66.49% of nests were built on them. In the logistic regression model, the number of whorls on a tree, canopy spread, and the height of the first branch determined whether a nest was present or absent on a tree. These results help to prioritize the tree attributes in a habitat conservation plan for vultures.

“…Many earlier studies on vultures also reported the continuous use of the same nesting site for many years (Rasmussen and Anderton, 2005;Davit, 2009;Kushwaha et al, 2009;Kanaujia et al, 2010;Vergara et al, 2010). Despite their declining status, since 2000, long-term studies on breeding ecology, an essential aspect to understand their reproductive performance in recent years, are still rare on WRV (Gill, 1921;Thakur, 2015;Samson and Ramakrishnan, 2020) and LBV (Kulshreshtha, 2001;Rasmussen and Anderton, 2005;Naoroji, 2007;Kushwaha et al, 2009;Kanaujia et al, 2013;Khatri, 2015;McClure et al, 2021). In this paper, we present long-term data collected from 2010 to 2021 on the breeding ecology, which includes breeding phenology and reproductive performance of Long-billed vulture and White-rumped vulture from Kaghaznagar Forest Division and its adjoining areas in the Deccan Plateau, India.…”

Gyps species declined rapidly between the late 1990s and early 2000s in southern Asia due to the use of diclofenac and are listed as Critically Endangered species. Long-term data on breeding ecology is essential to understand the population trends of these threatened species. This study assessed the breeding phenology and reproductive performance of two critically endangered Gyps species-Longbilled Gyps indicus (Scopoli) (LBV) and White-rumped Gyps bengalensis (Gmelin) (WRV) vultures-through long-term monitoring at breeding colonies in Kaghaznagar and Sironcha Forest Divisions in the Deccan Plateau of India between 2010 and 2021. LBV began their nest construction and copulation in the second week of October, and ended in the fourth week of November, while the WRV completed the same between the first and second weeks of October. LBV started egg-laying during the first week of December and ended in the first week of January, with a peak during the third week on 14 December, and the mean incubation period was 54±1 days. The WRV completed their egg-laying early, during the second and third weeks of October, and peaked during the second week on 14 October and had a relatively longer incubation of 61±1 days. For LBV, hatching peaked during the first week of February, and the mean nestling period was 103±2 days, while for WRV hatching peaked much earlier, during the third week of December and the mean nestling period was 105±1 days. Overall nest success, breeding success, and productivity estimated based on 159 breeding pairs of LBV observed over 12 years were lower compared to that of 124 breeding pairs of WRV observed over 6-year period. The decline in breeding success of LBV since 2019 is discussed in light of cattle poisoning reported in 2018, and the reopening of the Sirpur paper industry (Kaghaznagar) in 2017 that discharges its hazardous effluent into the Peddavagu stream. Therefore, the present study suggests long-term monitoring of breeding colonies including evaluation of the drivers of population and breeding, molecular and toxicological studies, and implementation of Vulture Safe Zones to save these critically endangered Gyps vultures from local extinction.
