Summary. In 2008 the International Commission for Zoological Nomenclature (ICZN) ruled that the name Streptopelia risoria (Linnaeus, 1758) should have priority for both African Collared Dove and its domestic form, Barbary Dove, as it is senior to S. roseogrisea (Sundevall, 1857). Many ignored the ruling in the belief that the ancestry of Barbary Dove is still unproven. Given the lack of a name-bearing specimen and in anticipation of the ICZN decision, in 2008 a neotype was designated for S. risoria. To clarify the taxonomic status of roseogrisea, as its original type series was mixed, in 2018 a neotype was also designated for this junior synonym of African Collared Dove. As the species was assumed to be polytypic, synonymisation of roseogrisea with risoria at species level was questioned thereafter. The results of a whole genome-resequencing study now show that African Collared Dove is the principal ancestor of Barbary Dove, and that the species is monotypic.

Summary. The two main populations of Parabuteo unicinctus have long been treated as subspecies of the same species: Harris's Hawk P. u. harrisi in the southern USA to Costa Rica, and Bay-winged Hawk P. u. unicinctus in South America. However, they differ considerably in their morphology, number of plumages, and behavioural ecology. Adult Harris's Hawk differs in multiple plumage characters from adult Bay-winged Hawk, and differences are even more marked in juvenile plumage. Harris's Hawk has two age-related plumages but Bay-winged Hawk shows delayed plumage maturation and has four such plumages. Harris's Hawk breeds and hunts cooperatively, whereas Bay-winged Hawk nests only in pairs, and hunts individually. There are no valid records of Harris's Hawk in South America. We believe that the differences in adult and juvenile plumages, the number of immature plumages, and differences in breeding and hunting mean that Harris's Hawk and Bay-winged Hawk are best treated as separate species.
总结。长时间以来，独角拟鹰的两个主要种群一直被视为同一物种的亚种:美国南部至哥斯达黎加的哈里斯鹰P. u. harrisi和南美洲的湾翼鹰P. u. unicinctus。然而，它们在形态、羽毛数量和行为生态学上有很大的不同。成年哈里斯鹰与成年湾翅鹰在多种羽毛特征上存在差异，在幼年羽毛上的差异更为明显。哈里斯鹰有两根与年龄相关的羽毛，但湾翼鹰的羽毛成熟时间较晚，有四根羽毛。哈里斯鹰是合作繁殖和狩猎的，而湾翅鹰则是成对筑巢，单独狩猎。在南美洲没有哈里斯鹰的有效记录。我们认为，成年和幼年羽毛的差异，未成熟羽毛的数量，以及繁殖和狩猎的差异，意味着哈里斯鹰和海湾翼鹰最好被视为单独的物种。

Summary. In a recent article (Bull. Brit. Orn. Cl. 142: 329–342), Matthew Halley contended that John James Audubon (1785–1851) lied about his discovery of Lincoln's Sparrow Melospiza lincolnii (Audubon, 1834) during his 1833 Labrador expedition. Extracts from the naturalist's journal, published after his death in a biography prepared by his widow, Lucy (1787–1874), states that he was aboard ship ‘Drawing all day’ when the specimen was collected by one of his assistants. Consequently, Halley submitted that Audubon’s claim in the Ornithological biography to having first sighted the bird was fabricated and that his granddaughter Maria R. Audubon (1843–1925) doctored her alternate version of the journal to be consistent before she destroyed the original. However, Halley overlooked critical facts, including evidence that Lucy’s manuscript was compiled and edited by others; the published work contained numerous errors; and the journal entries for the previous two weeks were misdated and sometimes conjoined from multiple days, proving that her journal was not a faithful transcription of the original.
总结。在最近的一篇文章(牛。英国人。内在的。马修·哈雷认为约翰·詹姆斯·奥杜邦(1785-1851)在1833年的拉布拉多探险中谎称他发现了林肯的麻雀Melospiza lincolnii (Audubon, 1834)。这位博物学家的日记摘录在他死后由他的遗孀露西(Lucy, 1787-1874)撰写的传记中发表，其中写道，当他的一位助手收集标本时，他正在船上“整天画画”。因此，哈雷提出，奥杜邦在《鸟类学传记》中声称第一次看到这种鸟的说法是捏造的，他的孙女玛丽亚·r·奥杜邦(Maria R. Audubon, 1843-1925)在销毁原始版本之前篡改了她的日记的另一个版本，以保持一致。然而，哈雷忽略了一些关键的事实，包括露西的手稿是由他人编辑的证据;出版的作品有许多错误;而且前两周的日志记录日期有误，有时甚至连用了好几天，这证明她的日志并不是原稿的忠实抄写。

Summary. I discuss why the tropical island of New Guinea has long been important in the development of our understanding of birds. There are two sets of reasons: New Guinea's birds, and its geography and peoples. New Guinea birds include: the famous birds of paradise, bowerbirds, and megapodes, which evolved in New Guinea (or New Guinea plus Australia) and are still concentrated there; pigeons, parrots, and kingfishers, which are especially species-rich and diverse in New Guinea and radiated there, whether or not they originally evolved there; and many groups that are morphologically and ecologically similar to European groups, such as ‘wrens’, ‘creepers’, and ‘nuthatches’, but that proved to be ‘lookalikes’ that evolved independently in New Guinea / Australia, just as numerous marsupial mammals and placental mammals converged on similar morphologies. Finally, the poisonous pitohuis and ifrit independently acquired the same neurotoxin as did South American poison-dart frogs; and a melampitta roosts and nests underground. The advantages offered by the island itself include: its equatorial location and its high mountains, so that New Guinea offers the entire range of habitats from coral reefs and rainforests through alpine grassland and glaciers on one short transect; the ‘right size’ (sufficient species to illuminate but not too many species so as to confuse); a simple geographic layout comprising a central mountain chain and its lowland ring; hundreds of islands of three types; virtually complete knowledge of the composition of its resident avifauna at the level of species; and the encyclopedic knowledge of birds among traditional New Guinea peoples. As examples of phenomena of general biological interest that New Guinea birds have illuminated, I discuss elevational sequences of congeners, culture in bowerbirds, evolution of ‘aggressive mimicry’ of larger bird species by smaller birds, brown-and-black mixed-species foraging flocks, and selection for and against overwater dispersal. These birds, landscapes, and topics are illustrated by photographs by K. David Bishop.
总结。我讨论了为什么热带岛屿新几内亚岛在我们了解鸟类的过程中一直很重要。有两种原因:新几内亚的鸟类，以及它的地理和人民。新几内亚的鸟类包括:著名的天堂鸟、园丁鸟和巨足鸟，它们在新几内亚(或新几内亚加澳大利亚)进化而来，目前仍集中在那里;鸽子、鹦鹉和翠鸟，这些物种在新几内亚尤其丰富多样，无论它们最初是否在那里进化，它们都在那里繁衍;以及许多在形态和生态上与欧洲类群相似的类群，如“鹪鹩”、“爬行动物”和“nuthatches”，但它们被证明是在新几内亚/澳大利亚独立进化的“类群”，就像许多有袋哺乳动物和胎盘哺乳动物在形态上趋同一样。最后，有毒的pitohuis和ifrit独立获得了与南美毒镖蛙相同的神经毒素;还有一只黑尾鼠在地下栖息和筑巢。岛屿本身提供的优势包括:它的赤道位置和高山，因此新几内亚提供了从珊瑚礁和热带雨林到高山草原和冰川的整个栖息地范围;“合适的大小”(足够的物种，以阐明，但不是太多的物种，以免混淆);一个简单的地理布局，包括中央山脉及其低地环;数百个三种类型的岛屿;在物种层面上对其留鸟区系的组成几乎有完整的认识;以及传统新几内亚人关于鸟类的百科全书式知识。作为新几内亚鸟类普遍感兴趣的生物学现象的例子，我讨论了同族的海拔序列，园丁鸟的文化，小型鸟类对大型鸟类的“侵略性模仿”的进化，棕色和黑色混合物种觅食群，以及对水上扩散的选择。这些鸟类、风景和主题都是由K. David Bishop拍摄的照片。

Summary. Ruby-throated Bulbul Rubigula dispar, currently Vulnerable on the IUCN Red List owing to trade pressure, is considered monotypic across its range on three Sundaic islands in Indonesia: Sumatra, Java and Bali. However, examination of photographs and museum specimen labels and measurement of 37 Sumatran and 50 Javan specimens indicate that birds from Sumatra differ from those on Java (type locality) and Bali in exhibiting a variably red (not pale yellow) iris and a slightly longer bill and wing. Consequently, we propose subspecies rank for the Sumatran population. We recommend that the two taxa be maintained pure in captivity and that any releases of confiscated birds take place on the correct island based on eye colour.

Summary. Based on 30 days of field surveys in the north-west of the state of Minas Gerais, Brazil, in 2014, I report notable records of 40 bird species. In total, 293 species were recorded at three sites, including 15 species at risk of extinction (at state, national or global levels) and another four species whose status is insufficiently known to be placed in any threat of extinction category in Minas Gerais or Brazil. Records of three species are new for the São Francisco basin, and 13 are new for north-west Minas Gerais. Among the rarest species reported are Dwarf Tinamou Taoniscus nanus, Jabiru Jabiru mycteria, Black Hawk-Eagle Spizaetus tyrannus, Ocellated Crake Micropygia schomburgkii, Uniform Crake Amaurolimnas concolor, Russet-mantled Foliage-gleaner Syndactyla dimidiata, Minas Gerais Tyrannulet Phylloscartes roquettei, Chapada Flycatcher Guyramemua affine, Reiser's Tyrannulet Phyllomyias reiseri, Rufous-tailed Attila Attila phoenicurus, Black-collared Swallow Pygochelidon melanoleuca and Blackish-blue Seedeater Amaurospiza moesta.

Summary. New Guinea and its satellite islands are justly renowned for their spectacular and highly diverse, endemic avifauna. The oceanic island of Biak and its satellites, in Teluk Cenderawasih (formerly Geelvink Bay), Papua province, Indonesia, has an avifauna of c.159 species including the largest number of endemics of any island in the New Guinea region: seven species are strictly endemic to Biak and another six are shared with other Teluk Cenderawasih islands but not Yapen. Despite Biak attaining an elevation of c.1,034 m there are no species whose range on Biak is known to be entirely montane. We provide a physical description of Biak and its twin Supiori, and discuss the biogeography and conservation of their birds. We present a detailed checklist of all species recorded to date. Since the publication in 1939 of Mayr & Meyer de Schauensee, 66 species have been added to the Biak list, of which Short-eared Owl Asio flammeus and Black-winged Stilt Himantopus himantopus are new for the entire Australo-Papuan region and Grey Heron Ardea cinerea only the second for the region and first for New Guinea; 47 of these additions are also first records for any island in Teluk Cenderawasih. An appendix summarises the distribution and status of birds in Teluk Cenderawasih (excluding mainland New Guinea species only on Yapen).
总结。新几内亚及其卫星岛以其壮观和高度多样化的特有鸟类而闻名。比亚克岛及其卫星岛位于印度尼西亚巴布亚省的Teluk Cenderawasih(以前的Geelvink湾)，拥有159种鸟类，其中包括新几内亚地区任何岛屿中最多的特有鸟类:7种是比亚克岛特有的，另外6种与其他Teluk Cenderawasih岛屿共有，但不包括雅本岛。尽管Biak的海拔为1034米，但在Biak上没有已知的完全山地分布的物种。本文对Biak及其孪生兄弟Supiori进行了物理描述，并对其鸟类的生物地理学和保护进行了讨论。我们提供了一份详细的清单，列出了迄今为止记录到的所有物种。自1939年《Mayr & Meyer de Schauensee》出版以来，已经有66个物种被添加到Biak名单中，其中短耳猫头鹰Asio flammeus和黑翅高跷Himantopus是整个澳巴巴布亚地区的新物种，灰鹭Ardea cinerea是该地区的第二种，是新几内亚的第一种;其中的47个新增记录也是新德拉瓦西直辖岛屿的首次记录。附录概述了新德拉瓦西岛的鸟类分布和现状(不包括亚彭岛上的新几内亚大陆物种)。

Since the publication in 1939 of Mayr & Meyer de Schauensee, 66 species have been added to the Biak list, of which Short-eared Owl Asio flammeus and Black-winged Stilt Himantopus himantopus are new for the entire Australo-Papuan region and Grey Heron Ardea cinerea only the second for the region and first for New Guinea; 47 of these additions are also first records for any island in Teluk Cenderawasih. An appendix summarises the distribution and status of birds in Teluk Cenderawasih (excluding mainland New Guinea species only on Yapen).","PeriodicalId":38973,"journal":{"name":"Bulletin of the British Ornithologists'' Club","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74153705","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}
