Summary. A review of eight molecular phylogenetic studies supports the distinctiveness of the genera Sasia/Verreauxia from Picumnus and casts doubt on the monophyly of Picumninae. We propose to restrict Picumninae to Picumnus and to place Sasia and Verreauxia in a new subfamily, Sasiinae.

Summary. The islands of the Wallacean biodiversity hotspot support diverse and highly endemic bird communities, yet remain ornithologically poorly studied. There is a particular paucity of data regarding breeding biology for the region's birds. Here, we help to address this research gap by collating observations of breeding evidence made during nearly 20 years of field work between 1999 and 2018 in south-east Sulawesi and its offshore islands. Data were collected between April and September, with a special focus on July and August, which is the dry season across the southern half of Sulawesi. In total, we summarise 1,064 observations of potential breeding in 66 species, of which 27 are Wallacean endemics (including the Critically Endangered Maleo Macrocephalon maleo), and 39 species of wider range (including the Endangered Milky Stork Mycteria cinerea). Records include species with little or no previously published information on their breeding biology, such as Pygmy Hanging Parrot Loriculus exilis, Sulawesi Pitta Erythropitta celebensis and an undescribed Zosterops species, provisionally referred to as Wangi-wangi White-eye.

Summary. The description of the Subantarctic Diving Petrel Pelecanoides urinatrix exsul Salvin, 1896, creates confusion because the type series contains specimens of three different taxa. Here we nominate a lectotype, thereby fixing the identity of this taxon, and restrict its type locality to the Baie de l'Observatoire, La Grande Terre, Kerguelen Islands, Indian Ocean. This stabilises its taxonomy.

Summary. Whether dark-morph Herald Petrel Pterodroma heraldica exists or not has been debated for many years. We summarise previous contributions on the subject, provide indisputable evidence of the dark morph, describe its plumage based on museum specimens and live birds, highlight differences between dark, light and intermediate morphs, and enumerate characters that relatively easily separate the dark morph from ‘all-dark’ Henderson Petrel P. atrata. Dark-morph Herald Petrel is scarce and local. Since the 1970s, records have been restricted to the central South Pacific at Mangareva Island (Gambier Islands) and Ua Pou (Marquesas Islands).
总结。关于黑变形海燕纹章翼龙病是否存在已经争论多年。我们总结了之前对该主题的贡献，提供了无可争辩的证据，根据博物馆标本和活鸟描述了其羽毛，突出了深色，浅色和中间形态之间的差异，并列举了相对容易将深色形态与“全黑”亨德森海燕区分开来的特征。黑变形海燕在当地稀少。自20世纪70年代以来，记录仅限于南太平洋中部的Mangareva岛(Gambier群岛)和Ua Pou (Marquesas群岛)。

Summary. Barking Owl Ninox connivens has two recognised subspecies in Australia: N. c. connivens and N. c. peninsularis. N. c. connivens currently includes the isolated south-west Australian population, which is separated from eastern populations by the Nullarbor Plain and from N. c. peninsularis to the north. N. c. connivens in south-west Australia occurs from near Perth in the north, east to Northam and south-east to Katanning and Bremer Bay; it has been treated subspecifically as N. c. addenda Mathews, 1912, but this name is not currently in use. Given concern over the apparent rarity of the south-west Australian population, we sought to compile all known historical and contemporary records in order to assess its conservation status and ecology. We located the holotype of N. c. addenda Mathews, 1912, and found only ten sightings in the past 20 years that met our criteria for acceptance. No sound-recordings or photographs of wild birds are known.
总结。吠叫鸮在澳大利亚有两个公认的亚种:北卡罗来纳鸮和北卡罗来纳半岛鸮。北卡罗来纳群岛目前包括孤立的西南澳大利亚人口，它被纳拉伯平原和北卡罗来纳半岛与东部人口分开。在澳大利亚西南部，北至珀斯附近，东至诺瑟姆，东南至卡坦宁和布雷默湾;它被当作n.c.增编Mathews, 1912年，但这个名字目前不使用。考虑到澳大利亚西南部种群的明显稀有性，我们试图汇编所有已知的历史和当代记录，以评估其保护状况和生态。我们找到了1912年N. c. addenda Mathews的全模照片，在过去的20年里，只有10次目击符合我们的接受标准。没有野生鸟类的录音或照片。

Summary. Blackpoll Warbler Setophaga striata migrates between its breeding grounds in northern North America and non-breeding areas in northern South America, mainly Amazonia, but the presence of apparently small numbers in southern South America suggests the existence of an additional wintering area. We investigated this possibility by reviewing available records, and report a new wintering record in South America's largest conurbation. Data from the literature, online platforms and field observations reveal 44 records over the last 52 years. Records are available from throughout the Atlantic Forest domain of south-east and southern Brazil, at all seasons, but mainly the austral summer and autumn. The concentration of records and permanence of some birds for several months at the same localities indicate a second wintering area for the species in south-east and south Brazil, north-east Argentina and south-east Paraguay.

We document the sighting of four New Zealand Storm Petrels Fregetta maoriana off Gau Island, Fiji, by summarising the circumstances and the identification and ageing of the birds. Like the first record off Gau in May 2017 (Flood & Wilson 2017), these sightings are significant for three reasons. They are only the second confirmed records of New Zealand Storm Petrel away from New Zealand / Australasia. They provide further evidence of long-distance dispersal / migration (Fiji is c .2,000 km north of New Zealand). New Zealand Storm Petrel remains listed as Critically Endangered (IUCN 2022). We undertook an eight-day pelagic expedition (25 May‒1 June 2022) to observe tubenoses off Gau (Ngau), Fiji. The vessel used was the 18-m sailing yacht Sauvage . Wind direction varied between north-east and south-east, and its speed between still and 35 knots, and sea state from flat to 2.5 m: 25–26 May north-east 15–25 knots, 27–29 May east-northeast 10–15 knots knots evening 28 May), 30 May east-southeast 0–5 knots (several hours of heavy rain mid-afternoon), 31 May–1 June east-southeast 10–15 knots.

我们记录了四只新西兰风暴海燕在斐济高岛的目击情况，总结了这些鸟的情况、身份和衰老情况。就像2017年5月高岛的第一个记录(Flood & Wilson 2017)一样，这些目击事件有三个重要原因。这是新西兰风暴海燕在新西兰/澳大拉西亚以外的第二个被证实的记录。它们提供了远距离扩散/迁徙的进一步证据(斐济位于新西兰以北约2000公里处)。新西兰风暴海燕仍然被列为极度濒危物种(国际自然保护联盟2022年)。我们进行了为期8天的远洋考察(2022年5月25日至6月1日)，以观察斐济高岛(Ngau)附近的结核。使用的船只是18米长的帆船“沙维奇”号。风向介乎东北至东南，风速介乎静止至35海里，海况介乎平缓至2.5米:5月25日至26日东北风15至25海里，5月27日至29日东北风10至15海里(5月28日晚间)，5月30日东南风0至5海里(下午有数小时大雨)，5月31日至6月东南风10至15海里。的

Summary. I present evidence of sympatric occurrence of two subspecies of Blue-crowned Manakin Lepidothrix coronata in south-west Amazonia. Specimens collected in eastern Acre in Brazil and northern Bolivia, as well as records from south-east Peru, indicate that L. c. exquisita and L c. caelestipileata both occur in the south-east of the Inambari centre of endemism, when compared to their respective holotypes. Thus, L. c. exquisita, which was considered endemic to central-north Peru, is also present in the lowlands of south-west Brazilian Amazonia and northern Bolivia, whilst caelestipileata, previously known from the Juruá–Madeira region in Brazil, is present further south, reaching south-east Peru and northern Bolivia.
总结。我提出的证据，蓝冠侏儒鳞翅目冠的两个亚种在西南亚马逊地区的同域发生。在巴西东部阿克里和玻利维亚北部收集的标本以及秘鲁东南部的记录表明，与各自的完整模式相比，L. c. exquisita和L. c. caelestipileata都出现在Inambari特有中心的东南部。因此，被认为是秘鲁中北部特有的l.c. exquisita也存在于巴西亚马逊西南部的低地和玻利维亚北部，而caelestipileata，以前在巴西Juruá-Madeira地区已知，存在于更南的地方，到达秘鲁东南部和玻利维亚北部。
