Slender-billed Curlew Numenius tenuirostris is Critically Endangered and may be extinct. Its breeding biology is known exclusively from early 20th-century accounts from central Russia and Kazakhstan, and the eggs were heretofore known from a single specimen in the Manchester Museum. Here, we provide details of five additional putative Slender-billed Curlew eggs held in public and private collections. The eggs show remarkable variation in size, with two being only 85% of the mean length and breadth. Notably, one of the putative clutches was from the European side of the Ural Mountains, far to the west of the established breeding range. Molecular identification would aid in identifying additional specimens, which would be easily confused with eggs of other Numenius.","PeriodicalId":38973,"journal":{"name":"Bulletin of the British Ornithologists'' Club","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88942139","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}

Geographical variation in Black Redstart Phoenicurus ochruros (S. G. Gmelin, 1774) calls 黑红start Phoenicurus ochruros (S. G. Gmelin, 1774)叫声的地理变异

Black Redstart Phoenicurus ochruros occurs over a broad range from Western Europe and north-west Africa to Central Asia. Seven subspecies are usually recognised, which can be divided morphologically into a grey-and-white-bellied western group (‘Western Black Redstart’; two subspecies) and an orange-bellied eastern group (‘Eastern Black Redstart’; five subspecies). Because vocalisations might help to understand relationships between these taxa, we analysed the calls of six of the seven subspecies. We demonstrate that calls can be grouped into one of three geographical variants. One is formed by the western subspecies breeding in Europe, the morphologically intermediate subspecies ochruros and Eastern Black Redstarts from the Altai and Mongolia. Further south-east, birds call at lower frequencies on average and within a smaller frequency range (group 2). The third group is formed by the eastern subspecies rufiventris which differs from all other taxa, with a descending instead of a rising call, given at much lower frequencies.","PeriodicalId":38973,"journal":{"name":"Bulletin of the British Ornithologists'' Club","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91241419","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}

Distributed in four areas of Africa (‘Eastern’—east of the Gregory Rift Valley from central Kenya south to Malawi; ‘Central’—west of the Gregory Rift from western Kenya and western Uganda south to Burundi and eastern Democratic Republic of Congo; ‘Western’—Nigeria and Cameroon plus Bioko; and Angola), Bar-tailed Trogon Apaloderma vittatum is at present widely judged to be monotypic. However, photographic evidence reveals three different facial patterns in these populations, with a bare ear spot and whitish-green bill in Eastern and Angolan birds, a bare ear spot, golden-yellow bill and bare gape line in Central birds, and these same features plus a distinct bare crescent above the eye in Western birds. Central and Western birds also have broader, more distinct barring on the wing panel. Moreover, there is a stepped cline in sizes in these three distinct populations, from Eastern plus Angola (largest) through Central to Western (smallest), with Bioko birds having notably short tails; and songs also decelerate from east to west, but with too much overlap to be diagnosable. Nevertheless, under the Tobias criteria the morphological differences of Central and Western birds vs. Eastern and Angolan populations accord the former species rank, for which the name camerunense is available. This latter species itself breaks into three subspecies, with the nominate in Nigeria and Cameroon, francisci on Bioko, and a new name for the hitherto taxonomically unrecognised Central populations.","PeriodicalId":38973,"journal":{"name":"Bulletin of the British Ornithologists'' Club","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88362887","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}

A new subfossil ground thrush (Turdidae: Geokichla) from Mauritius, Mascarene Islands 马斯卡林群岛毛里求斯地画眉亚化石一新(土画眉科:地画眉亚化石)

Geokichla ground thrushes (Turdidae) are widely distributed, in Siberia, South-East Asia, Indonesia, the Indian Subcontinent, Nicobar and Andaman Islands, and continental Africa. Based on recently discovered subfossil remains, I describe a Geokichla from Mauritius, a new genus for the Mascarene Islands, which presumably became extinct historically, although it seems never to have been reported in the literature. The new species appears closely related to the extant Orange-headed Thrush G. citrina of South-East Asia, so probably island-hopped via the Nicobar or Andaman Islands to Mauritius during low sea level stands, as did some other Mauritian endemic birds. Like Geokichla in general, the Mauritius species probably inhabited the understorey or forest floor, and as a result disappeared due to the introduction of invasive species, especially rats, by humans.","PeriodicalId":38973,"journal":{"name":"Bulletin of the British Ornithologists'' Club","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86458172","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}

The first records of Swallow Tanager Tersina viridis in Uruguay were made in 2012 and 2022 in different regions of the country.

This is the first in a planned series of articles about the breeding behaviour of Brazilian birds. Field work has been carried out in various regions of Brazil since the 1980s.

Many data are presented scientifically for the first time. In this first paper, we present data for 16 species: Greater Rhea Rhea americana (two nests, including the first information from north-east Brazil), Small-billed Tinamou Crypturellus parvirostris (20 nests), Red-winged Tinamou Rhynchotus rufescens (three nests), Spotted Nothura Nothura maculosa (11 nests), Horned Screamer Anhima cornuta (four nests, possibly with the first biometrics of eggs in the wild from Brazil), Southern Screamer Chauna torquata (five nests), White-faced Whistling Duck Dendrocygna viduata (three nests), Black-bellied Whistling Duck D. autumnalis (eight nests), Muscovy Duck Cairina moschata (two nests), Brazilian Teal Amazonetta brasiliensis (one nest), White-cheeked Pintail Anas bahamensis (one nest), Rusty-margined Guan Penelope superciliaris (seven nests, probably with the first data on reproductive success), Chaco Chachalaca Ortalis canicollis (one nest), East Brazilian Chachalaca O. araucuan (one nest), Least Grebe Tachybaptus dominicus (six nests) and Pied-billed Grebe Podilymbus podiceps (one nest).","PeriodicalId":38973,"journal":{"name":"Bulletin of the British Ornithologists'' Club","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89963585","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}
