John James Audubon (1785–1851) claimed to have personally discovered Lincoln's Sparrow Melospiza lincolnii (Audubon, 1834) in his published account of that species. However, his narrative is contradicted by his wife Lucy's transcript of his diary. A second diary transcript, published by his granddaughter Maria, fully complies with Audubon's published account. The unpublished diary of Thomas Lincoln (1812–83), for whom the sparrow was named, relocated after nearly a century, provides support for Lucy's version. The most parsimonious explanation for the evidence presented here is that Audubon (1834) fabricated his story about discovering Lincoln's Sparrow; then Maria doctored her published transcript of his diary to bring the primary record into alignment with his false narrative. This study sheds light on the ‘primary source problem’ which pervades Audubon scholarship, and highlights the need for a systematic review of his contributions. ‘Drawing all day.’—Audubon in Buchanan (1868: 268)","PeriodicalId":38973,"journal":{"name":"Bulletin of the British Ornithologists'' Club","volume":"73 1","pages":"329 - 342"},"PeriodicalIF":0.0,"publicationDate":"2022-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85637518","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}

White-cheeked Turaco Menelikornis (leucotis) leucotis and Crimson-crested Turaco M. (l.) donaldsoni have long been treated as conspecific. Because of the lack of data concerning their distribution and areas of potential geographical overlap, they have been considered to be parapatric at most. In 2019 and 2021, we conducted a field study that produced nearly 40 records of the two taxa. In the study area, which stretched 120 km north to south from the upper Shabelle Valley via the Oda and Bale Mts. to Harenna Forest, both leucotis and donaldsoni occurred. The presence of both taxa was recorded across c.50 km west to east, which indicates an area of range overlap of about 6,000 km2. Sympatry between leucotis and donaldsoni, together with clear differences in morphology (mainly crest colour) as well as molecular evidence, strongly support treating them as different species.","PeriodicalId":38973,"journal":{"name":"Bulletin of the British Ornithologists'' Club","volume":"42 1","pages":"343 - 353"},"PeriodicalIF":0.0,"publicationDate":"2022-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86399407","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}

From the summer of 2020 onwards, a large part of the British far-right field has been involved in mobilisations around this issue. It is possible to identify several types of actors: single-issue organisations, political organisations and video activists.The repertoire of action is similar to that of the Calais groups, mixing elements of the repertoire of classic social movements and of vigilantism. It should be noted that anti-migrant vigilantism, unlike in France, does not lead to violence but remains purely performative for social media audiences.These actors link the narrow issue of small boat crossings to broader themes such as the supposed threat posed by Islam to British society. The most radical activists connect the crossings to a civilisational peril that threatens the West with extinction. Most of the groups can be classified in a political space that overlaps with the radical right and civic nationalism, with the exception of a few actors who are simultaneously situated within the field of ethno-nationalism and within the extreme right wing.","PeriodicalId":38973,"journal":{"name":"Bulletin of the British Ornithologists'' Club","volume":"1 1","pages":"104-133"},"PeriodicalIF":0.0,"publicationDate":"2022-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147883923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It aims to consider the link between vigilantism and the social reaction to migration. Indeed, the social reaction to migration has been an important trend in the political game in Western Europe and North America, partly explaining the electoral support for the far right. The rejection of migration is fuelled by a series of cause entrepreneurs. Anti-migrant vigilantism seeks to frame migration as an issue to be considered primarily through a law and order prism. In the wake of the 2015 ‘migrant crisis’, many anti-migrant groups in Europe, most often linked to the far right, have sprung up to ‘secure’ frontiers.The social reaction to migration can also be explained by underlying trends. First of all, the theory of cleavages asserts that the right–left cleavage has been joined by another political cleavage between communitarianism and cosmopolitanism. Moreover, the social reaction must also be understood in the light of an economic discourse that promises the local working classes an improvement of their socioeconomic conditions, conditional on the exclusion of the immigrant parts of the working classes.","PeriodicalId":38973,"journal":{"name":"Bulletin of the British Ornithologists'' Club","volume":"1 1","pages":"67-82"},"PeriodicalIF":0.0,"publicationDate":"2022-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147912593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The status of three Sternula terns in southern and eastern Africa and the Indian Ocean is updated based on observations in Mozambique during October 2009–August 2021. Damara Tern S. balaenarum and Saunders's Tern S. saundersi, both new to Mozambique, were found at the San Sebastian Peninsula in August 2018 and have been recorded regularly since. Damara Tern arrived in May, numbers were lower June–July, with a peak of 100+ in August–October. Breeding plumage was assumed by late October and all departed in early November; those aged were all adults. Observations of ringed birds suggested they originated from colonies in South Africa. Numbers of Damara Tern reached the Key Biodiversity Area designation threshold population for the site in 2020. These are the first records of large numbers of Damara Tern in the Indian Ocean, whilst timings suggest the species is partly transient at the site and may also occur further north. Saunders's Tern was recorded at San Sebastian in all months except March and April, with 5–80 regularly present, and peak numbers perhaps in October–December. Birds were observed in a range of plumages in all months, from non-breeding, transitional to full breeding. Courtship feeding was observed in September–November suggesting at least some attempt to breed locally, although disturbance is high. Birds in non-breeding plumage may stem from Northern Hemisphere breeding localities. Little Tern S. albifrons was a numerous migrant in southern Mozambique in October–May, peaking in April when large numbers were observed during pelagic trips to the continental shelf edge, and at onshore roost sites including San Sebastian. Smaller numbers fed in coastal lagoons and freshwater lakes. Three Little Terns had been colour-ringed in Israel.","PeriodicalId":38973,"journal":{"name":"Bulletin of the British Ornithologists'' Club","volume":"11 1","pages":"190 - 208"},"PeriodicalIF":0.0,"publicationDate":"2022-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74612666","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}

Sclater, 1861, has recently been restored to recognise the genetic monophyly of four Neotropical tanager species, formerly placed in the genus Hemispingus Cabanis, 1851, which are little known and poorly represented in museum collections: Oleaginous Hemispingus Sphenopsis frontalis (von Tschudi, 1844), Black-eared Hemispingus S. melanotis (P.

Only ten study skins of S. ochracea are known in collections; prior to this study, just seven were known and no collection had adults of both sexes. The paucity of specimens has caused a considerable amount of confusion about the morphology of S. ochracea, both in published literature and private discussions among ornithologists. To review species limits, I assembled and photographed a comprehensive sample of study skins of Sphenopsis species, including S. ochracea study skins of both sexes, under a single light source, and compared plumage characters to published colour standards. I also quantified and analysed morphometric variation.

The eastern species, here re-named Ventriloquial Oriole O. consobrinus, is characterised by plumage distinctions, most notably a more male-like coloration in females, and a characteristic ventriloquial song unique among the region's orioles. The precise contact zone of the two species on Borneo is incompletely mapped. Their populations on Borneo show pronounced character displacement whereby individuals of O. xanthonotus on other landmasses are significantly larger than Bornean individuals, presumably to prevent non-adaptive hybridisation with the larger Ventriloquial Oriole along their Bornean contact zone.","PeriodicalId":38973,"journal":{"name":"Bulletin of the British Ornithologists'' Club","volume":"18 1","pages":"254 - 267"},"PeriodicalIF":0.0,"publicationDate":"2022-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75667084","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}

B. Tristram (Gurney 1882a). Among them were three adult females, all taken at Blanche Bay in June 1879, of a species that he considered with some reservations to be Urospizias etorques Salvadori, 1875, from New Guinea, which is now treated as a junior synonym of Accipiter hiogaster leucosomus (Sharpe, 1874). Gurney (1882a) in fact based this assessment on four New Britain specimens, the three received via Tristram plus an adult male, collector unstated, preserved in the then British Museum (now Natural History Museum, NHMUK). His reservations were largely the result of not having to hand an adult U. etorques from New Guinea with which to compare the New Britain specimens. Shortly thereafter, Gurney (1882b) revisited the issue, the Norwich Museum (later Castle Museum, Norwich) having now obtained an adult female U. etorques from the Astrolabe Mountains, New Guinea, collected by Andrew Goldie. This persuaded him that the New Britain specimens indeed formed a new species, which he named Urospizias dampieri, now Accipiter hiogaster dampieri, after the famous navigator William Dampier (1651‒1715), who in 1699 had been the first European to discover the New Britain archipelago. As evidence, Gurney noted the smaller size of the New Britain females, as well as reiterating subtle plumage distinctions that he had previously mentioned (Gurney 1882a), derived from Salvadori’s (1880) discussion of U. etorques. Although presenting mensural details for the New Guinea bird newly to hand, Gurney (1882b) did not repeat them for the New Britain birds, but instead referred to those already presented in Gurney (1882a). Possibly due to this lack of precise mention of the relevant New Britain specimens in the species description by Gurney (1882b), the syntypes on which this taxon was based appear to have been overlooked subsequently. Checking the published catalogue of Tristram (1889: 59) reveals that he retained two of Richards’s specimens (a and b under Astur etorques), which subsequently passed with much of his bird collection to what is now National Museums Liverpool (NML); these specimens are now registered as NML-VZ","PeriodicalId":38973,"journal":{"name":"Bulletin of the British Ornithologists'' Club","volume":"11 1","pages":"273 - 274"},"PeriodicalIF":0.0,"publicationDate":"2022-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80590888","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}
