Summary. In the 19th century the black-shouldered variety of Indian Peafowl Pavo cristatus was erroneously viewed by many as a separate species, named P. nigripennis. Others had doubts about its taxonomic status, but Darwin presented firm evidence for it being a variety under domestication, which treatment is now well established and accepted. It being a colour variation rather than a wild species was important for Darwin to prove, as otherwise it could undermine his theory of slow modification by natural selection in the wild. ‘I cannot consider it a domesticated variety, because the differences in both sexes appear to be constant, and to descend to the progeny’ (Sclater 1860: 222). ‘The black-shouldered peacock is a variety, the case is the most remarkable ever recorded of the abrupt appearance of a new form, which so closely resembles a true species that it has deceived one of the most experienced of living ornithologists’ (Darwin 1868: 292).

Summary. Rüppell's Parrot Poicephalus rueppellii was until recently considered to be a monotypic species. Birds from parts of north-western and west-central Angola, however, differ significantly in colour and size from the better-known populations across the rest of their range, which fact was overlooked until very recently. Because the name rueppellii was originally applied to the less-known Angolan population, it was the commoner southern population that lacked a taxonomic identity. The latter was described as Poicephalus rueppellii mariettae Hubers & Schnitker, 2022.

Summary. Chestnut Owlet Glaucidium (capense) castaneum and Albertine Owlet G. (c.) albertinum are poorly known members of the African Barred Owlet Glaucidium capense complex, confined to the Albertine Rift of East Africa. Recent taxonomic treatments have seen them variously considered as subspecies of capense, as separate monotypic species or, in the case of castaneum, a polytypic species. A paucity of museum material and field knowledge of each, combined with oversight and misinterpretation of some primary literature, has contributed to this uncertainty. This study reassesses their status and corrects numerous errors, misunderstandings and contradictions concerning specimen material, distribution, morphology and voice. Only four specimens of castaneum are known, there are no documented observations of the bird in life and no acoustic recordings. There are seven specimens of albertinum in collections. No field sightings have ever been documented but several recordings attributed to albertinum exist. Despite its close similarity to the voice of capense, there is no published evidence that albertinum reacts to playback, unlike the remaining taxa of the complex. I conclude that castaneum is a modestly distinct subspecies of capense. In contrast, albertinum, which differs conspicuously from the others in the complex by its disproportionately short tail, and which may be parapatric with castaneum, merits treatment as a species.
总结。栗子Owlet Glaucidium (capense) castaneum和Albertine Owlet G. (c.) albertinum是非洲斑Owlet Glaucidium capense复合体中鲜为人知的成员，局限于东非Albertine裂谷。最近的分类处理已经看到它们被不同地认为是capense的亚种，作为单独的单型种，或者在castaneum的情况下，一个多型种。博物馆材料和各自领域知识的缺乏，加上对一些原始文献的疏忽和误解，导致了这种不确定性。本研究重新评估了它们的地位，并纠正了有关标本材料、分布、形态和声音的许多错误、误解和矛盾。人们只知道4个卡斯塔尼姆的标本，没有关于这种鸟生活中的观察记录，也没有声音记录。阿尔贝属植物共有7个标本。从未有过野外目击记录，但有几次记录被认为是albertinum的存在。尽管它的声音与capense的声音非常相似，但没有公开的证据表明albertinum对回放有反应，不像该复合体的其他分类群。我的结论是，castaneum是capense的一个适度独特的亚种。相比之下，由于其不成比例的短尾而与其他植物明显不同的albertinum，可能与castaneum并列，值得作为一个物种对待。

Summary. We review specimens and sight records of small black-and-white Puffinus shearwaters in Kenya and Tanzania. An early specimen of an Audubon's Shearwater P. lherminieri sensu lato found inland at Limuru, Kenya in October 1963, long held to represent taxon bailloni (now treated as Tropical Shearwater P. bailloni), is reassigned here to P. b. nicolae. We refer three other specimens and two well-documented sight records to Persian Shearwater P. persicus persicus and a third sight record in northern Tanzania to P. persicus. We suggest that nominate persicus is a regular visitor to the central Kenya coast in December–March, probably as far south as the Pangani region of north-east Tanzania at least, concurrent with a seasonal upwelling event on the Kenya Banks associated with the north-east monsoon. Tropical Shearwater, however, is no more than a rare visitor to East African shores based on current evidence. Our data clarify the status of these shearwaters in the region, provide additional biometric data to complement published sources, and extend the western Indian Ocean non-breeding range of the nominate subspecies of Persian Shearwater approximately 2,000 km south from northern Somalia.
总结。我们回顾了在肯尼亚和坦桑尼亚的黑白小海鹦的标本和视觉记录。1963年10月在肯尼亚Limuru内陆发现的Audubon Shearwater P. lherminieri sensu lato的早期标本，长期以来被认为是bailloni分类单元的代表(现在被视为热带Shearwater P. bailloni)，在这里被重新分配给p.b. nicolae。我们将另外3个标本和2个有完整记录的景象记录归为波斯Shearwater P. persicus persicus，并将坦桑尼亚北部的第三个景象记录归为P. persicus。我们认为，在12月至3月期间，提名佩西卡斯是肯尼亚中部海岸的常客，至少可能向南延伸到坦桑尼亚东北部的潘加尼地区，同时与东北季风有关的肯尼亚河岸的季节性上升流事件同时发生。然而，根据目前的证据，热带海鸥只不过是东非海岸的罕见游客。我们的数据阐明了这些剪切水在该地区的状况，提供了额外的生物特征数据来补充已发表的资料，并将波斯剪切水的指定亚种的非繁殖范围从索马里北部向南约2000公里扩展到西印度洋。

Summary. Dulit Partridge Rhizothera dulitensis is an enigmatic galliform endemic to the Bornean highlands. Usually, the species is reported as having been collected at four localities (three in Sarawak, one in Sabah) and as recently as the 1930s. However, a review of the evidence (just eight known specimens) finds that it can be confirmed at only three sites, and the whereabouts of one of these has previously been misunderstood. Moreover, the specimens were procured over just eight years, between 1894 and 1902, with recent suggestions of the species' collection in the 1930s probably a misinterpretation of a single source. With more than 120 years since the last record, there is no information on its current population size and trend, such that R. dulitensis is probably best listed as Data Deficient on the IUCN Red List. Surveys of little-explored parts of its presumed range, especially those furthest from habitation, are urgently required.

Summary. From its description in 1863 until the 1920s, the authority for the name Spizaetus philippensis was almost universally agreed to be J. H. Gurney, but from the 1930s it has normally been ascribed to J. Gould. This paper demonstrates that this alteration of the authority was incorrect; it should be J. H. Gurney. The two syntypes of the taxon are currently held by the Natural History Museum at Tring.

Summary. Mexican Woodnymph Thalurania ridgwayi was long included in the genus Thalurania. A previously published molecular phylogenetic study found that this species is in fact sister to the genus Eupherusa. We discuss whether ridgwayi is better lumped with Eupherusa or placed in a different genus, and consider that the latter arrangement best reflects the multiple morphological differences between ridgwayi and Eupherusa. Consequently, we describe a new genus for ridgwayi.

Summary. We report five new records of Blue Petrel Halobaena caerulea in Uruguay; three individuals were found stranded on the coast in 2005, 2016 and 2018, and two were recorded at sea in the economic exclusive zone in 2021 and 2022. These few records suggest that the species' presence in Uruguayan waters is no more than occasional. However, its similarity to, and association with prions, together with the fact that this petrel does not usually approach fishing vessels, could mean that it is under-recorded.

Summary. We report the first record of Lesson's Seedeater Sporophila bouvronides, a South American species, in Costa Rica. It was seen at Tortuguero, in the lowlands of north-east Costa Rica in June 2022. The record is perhaps explained by the passage of a tropical storm that moved north-west from off northern South America.
