{"title":"Exceptional nest attendance and solo breeding attempt by an African White-backed Vulture.","authors":"T. Johnson","doi":"10.4314/vulnew.v74i1.5","DOIUrl":"https://doi.org/10.4314/vulnew.v74i1.5","url":null,"abstract":"African White-backed Vultures Gyps africanus, like many bird species (Cockburn 2006), are monogamous and exhibit bi-parental care, where both birds share the incubation and feeding responsibility equally (Mundy et al. 1992). This is a common breeding strategy in birds because it enables one parent to incubate an egg whilst the other parent can forage, ensuring the egg is always attended and less vulnerable to predation (Cockburn 2006). Bi-parental breeding is an effective reproductive strategy for White-backed Vultures because they exhibit a lengthy breeding period, incubating one egg for 56 days, before rearing a chick for 120-125 days (Mundy et al. 1992). After this, the fledgling will still be partially dependent on its parents for up to a further 5-6 months, in total, equating to nearly one year of incubation and feeding responsibility (Mundy et al. 1992). This level of breeding effort, whilst challenging for a pair of birds, would be almost impossible for a single bird. The extended absences required to forage efficiently would leave the nest unattended and the egg vulnerable to predation. Despite the difficulty inherent in a single bird attending the nest, here I present evidence of unusually long nest attendances and a solo egg incubation attempt by a White-backed Vulture.","PeriodicalId":404970,"journal":{"name":"Vulture News","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123909014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both these observations were made in areas where Himalayan Vulture is not indicated to occur by existing range maps.

The objectives of this study were to: (i) assess local people’s knowledge and perceptions of vultures and their ecological importance and (ii) determine the socio-cultural uses of vulture body parts in communities adjacent to the northern Gonarezhou National Park, south-eastern Zimbabwe. Semi-structured questionnaires were administered through interviews with randomly selected household representatives (n = 81) in August 2016. Our results showed that the majority of study respondents, 72.9% (n = 59) reported the need to conserve vultures for their socio-ecological importance to the local communities. Respondents acknowledged the importance of vultures as agents of cleaning the environment, hence maintaining ecosystem health. However, a concern for vulture population decline due to poisoning was reported by most respondents of 71.6 % (n = 58). Vulture’s organs were reported to be used mostly to enhance dreaming or having visions about the future followed by healing and lastly magic use. We recommend enhanced conservation awareness and education on vultures’ conservation and restrictions on access to and use of hazardous chemicals which may likely be used in poisoning wildlife.","PeriodicalId":404970,"journal":{"name":"Vulture News","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115548784","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"First confirmed record of Rüppell’s Vulture Gyps rueppelli from the Gorongosa National Park, central Mozambique.","authors":"A. Botha, J. R. Román","doi":"10.4314/VULNEW.V74I1.6","DOIUrl":"https://doi.org/10.4314/VULNEW.V74I1.6","url":null,"abstract":"Rüppell’s Vulture Gyps rueppelli is a large, cliffnesting species of Old World vulture which occurs across sub-Saharan west-, central and east Africa and extends as far south as the extreme north of Mozambique. It is also considered to be an irruptive and local migrant (Bildstein 2006) and the species is now regularly recorded in small numbers in Spain, presumably following migratory immature Eurasian Griffons Gyps fulvus returning to their natal areas in Europe at the start of the northern summer (Ferguson-Lees and Christie 2001, De Juana 2006). Individual Rüppell’s Vultures have also been recorded on several occasions at various sites in southern Africa (Kemp and Kemp 1998), with the best-known example being of an individual that has been frequenting the Blouberg Cape Vulture Gyps coprotheres colony in Limpopo, South Africa for several years and which is rumoured to possibly be breeding with an individual of the latter species. However, it can in no way be regarded as a regular visitor to the southern African sub-region where it is regarded as a rare vagrant (Mills 2005). We are not aware of any previous records of this species from southern or central Mozambique. Gorongosa National Park, located in the Sofala province of central Mozambique is therefore not an area where Rüppell’s Vulture has been recorded previously. As part of a study on the vultures of Gorongosa National Park, the Intermountain Bird Observatory (IBO) from Boise State University, the Endangered Wildlife Trust, Hawk Conservancy Trust and Wageningen University are looking at the extent and rate of consumption of carcasses by the suite of five resident vulture species that frequent the Park. Camera-traps are regularly placed at carcasses of varying size in different habitats for this purpose. On the 15 of November 2017, camera-traps were placed at two separate carcasses, that of a Waterbuck Kobus ellipsiprymnus (18.89599S 034.37322E) and Common Reedbuck Redunca arundinum (18.89036S 034.36866E) in the vicinity of the Musikadzi-river. When IBO biologist Juan Ramiréz Román reviewed the images taken at the carcasses on the day, he noticed what appeared to be an immature Rüppell’s Vulture feeding among the African White-backed Gyps africanus and Lappet-faced Vultures Torgos tracheliotos and Marabou Storks Leptoptilos crumeniferus. The bird was photographed (Figs 1-3) at both carcasses about five hours apart. What appeared to be the same bird was again captured on camera at a Common Reedbuck carcass on the 16 of November 2017 (Fig. 4). Initial confirmation of identification and age was made based on plumage and other characteristics from a recent publication by Rodríguez and Elorriaga (2016). The images were sent to vulture experts with extensive experience working with the species in the field who confirmed the identification and age of the bird and substantiated what seems to be the first confirmed record for this species from central Mozambique and for the Gorongosa National Park.","PeriodicalId":404970,"journal":{"name":"Vulture News","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125857142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

More positive are updates including new tracking projects of Egyptian vultures in Arabia, Eurasian Griffons in Europe, and Nepalese wild and for the first time released white-rumped vultures in South Asia. Read on for more updates from around the globe... Perhaps the most significant news is that the CMS Vulture MsAP (Old World vultures action plan) was endorsed and adopted at the CMS COP12 in Manila, Philippines in October 2017. The action plan document (available here) contains a lot of updated information, but most significantly, provides an agreed framework for priority actions to conserve the 15 Old World vulture species in Africa-Eurasia. We take this opportunity to thank all VSG members and contributors who participated in the drafting of this important document. However, the adoption of the plan is just the beginning, and the most critical step, its implementation, is the new challenge that requires more capacity and substantial funding. The VSG will continue working with partners, members, and the range governments to secure the resources and support crucially needed.","PeriodicalId":404970,"journal":{"name":"Vulture News","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115275862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite this, the Griffon Vulture is still one of the least monitored major species in the Strait of Gibraltar. On assessing the weather forecasts during the autumn of 2015 it was predicted that the 28th October was a possible vulture migration “D-Day”.
