The Neotropical genus Nemosia comprises just two species, Hooded N. pileata and Cherry-throated Tanagers N. rourei, and their breeding biology is poorly known. Here we provide new information based on five nests of N. pileata and review existing data in the literature. When an active nest was found, it was visited every 3–4 days, or every second day near hatching or fledging. Monitoring was conducted by direct observation from hides sited 4–8 m from the nest. We estimated nest height above ground by eye to the nearest 0.5 m. Nestling period was estimated from hatching of the last chick to fledging of the first chick. Three nests had two eggs each, one nest had two nestlings, and one nest had one egg and two nestlings when found. Eggs were pointed, ovoid, and greenish with purplish-black spots all over. Eggs from four nests measured 20.5 ± 0.6 × 15.4 ± 0.3 mm and had mass 2.17 ± 0.22 g (n = 7). Five nestling from two nests were monitored. They hatched with a little white down covering the brown-orangey skin, a salmoncoloured bill, a red mouth, and orangey-brown legs and feet. A pair brought six food items (three each) in 100 minutes (to a nest with two nestlings). Of three of the five nests monitored, one fledged two young and the other two were predated. The nesting period (October–April) overlaps the dates of other published records, but differs between regions and shows a complex relation to rainfall. Our data on nests, eggs and nestlings of N. pileata improves our understanding of its reproductive biology and could assist in conservation measures for the Critically Endangered N. rourei.","PeriodicalId":38973,"journal":{"name":"Bulletin of the British Ornithologists'' Club","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86682615","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}

We report pelagic observations from around Rapa Island and Marotiri Rocks, in the Austral Islands, French Polynesia, made during the first dedicated at-sea survey of birds in the region, during October–December 2019. We recommend that the regional occurrence of several seabird species be modified and that the list of avifauna for Rapa and Marotiri, the Austral Islands, and East Polynesia variously be amended to include Juan Fernández Petrel Pterodroma externa, Mottled Petrel P. inexpectata, Gould's Petrel P. leucoptera, Stejneger's Petrel P. longirostris, Buller's Shearwater Ardenna bulleri and Arctic Skua Stercorarius parasiticus. Two Gould's Petrels were behaving as if breeding, and the timing of egg laying by Christmas Shearwater Puffinus nativitatis is apparently somewhat earlier than the species' other populations. We found Polynesian Storm Petrel Nesofregetta fuliginosa foraging in large numbers around Marotiri suggesting a hitherto unrecognised and perhaps significant breeding population; we also found large numbers around Rapa. Titan Storm Petrel foraged off Rapa in substantial numbers and c.5% appeared to be a variant, raising the possibility of two distinctive phenotypes. We include at-sea images and a field description of ‘classic’ Rapa Shearwater Puffinus myrtae, and report an unidentified small Puffinus seen at Marotiri. Our survey adds significant new information to knowledge of seabirds in this region, and in combination with previous work argues strongly for the conservation of Rapa, Marotiri and the surrounding ocean’s pelagic birds.","PeriodicalId":38973,"journal":{"name":"Bulletin of the British Ornithologists'' Club","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83614193","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}

{"title":"The correct name of the antpitta clade","authors":"J. Gaudin, L. Raty, G. Sangster","doi":"10.25226/bboc.v141i3.2021.a11","DOIUrl":"https://doi.org/10.25226/bboc.v141i3.2021.a11","url":null,"abstract":"Antbirds, which currently constitute three families, were formerly placed in the single family Formicariidae (Wetmore 1930, Peters 1951, Morony et al. 1975), until Sibley & Ahlquist (1990) showed that typical antbirds (Thamnophilidae) and ground antbirds and antpittas (Formicariidae) are not sister groups. More recent phylogenetic analyses have further clarified relationships among antbirds, and have shown that the ground antbirds (Formicarius, Chamaeza) and antpittas form distinct clades that are also not sister taxa (Irestedt et al. 2002, Chesser 2004, Rice 2005a,b, Moyle et al. 2009, Harvey et al. 2020). The antpitta clade is well supported and comprises the genera Grallaria, Grallaricula, Myrmothera, Hylopezus and Cryptopezus (Rice 2005a,b, Moyle et al. 2009, Carneiro et al. 2019, Harvey et al. 2020). Several recent works have used the family-group name Grallariidae for the antpitta clade (Irestedt et al. 2002, Moyle et al. 2009, Ohlson et al. 2013, Dickinson & Christidis 2014, Fjeldså et al. 2020). This name was introduced at subfamily rank by Sclater (1890) (not Sclater & Salvin 1873, as listed by Bock 1994). Bock (1994) correctly pointed out that because the genus name Hypsibemon Cabanis, 1847, was synonymised with Grallaria Vieillot, 1816, prior to 1961, and Hypsibemoninae Sundevall, 1872, has been replaced by Grallariidae, the latter name takes precedence from 1872. Nevertheless, the family-group name Myrmotherinae MacGillivray, 1839, predates Grallariinae P. L. Sclater, 1890 [1872], by several decades. Myrmotherinae cannot be regarded as a ‘nomen oblitum’ (sensu ICZN 1999, Art 23.9.1) because it was used as a valid subfamily name in Cory & Hellmayr (1924), Zotta (1938) and Schwartz (1957). Thus, the correct name of the antpitta clade is Myrmotheridae. We have traced the erroneous use of Grallariidae for the antpitta clade to Lowery & O’Neill (1969), who appear to be the first to have re-used this name (as Grallariinae). Phylogenomic analyses have shown that the antpitta clade (Myrmotheridae) is sister to a clade consisting of the tapaculos (Rhinocryptidae Wetmore, 1926; not Wetmore 1930, as listed by Bock 1994), the ground antbirds (Formicariidae G. R. Gray, 1840), and the ovenbirds and woodcreepers (Furnariidae G. R. Gray, 1840) (Oliveros et al. 2017, Feng et al. 2020, Harvey et al. 2020), although some previous studies (e.g., Rice 2005b, Moyle et al. 2009) had found the antpittas to be sister solely to the tapaculos. The latter two clades were combined by Moyle et al. (2009) in the superfamily Grallarioidea. The genus Rhinomya Geoffroy Saint-Hilaire, 1832, was synonymised with Rhinocrypta G. R. Gray, 1841, prior to 1961, and Rhinomyadae d’Orbigny & Lafresnaye, 1837, has been replaced by Rhinocryptidae. The latter thus takes precedence from 1837, and is senior to both Myrmotherinae and Grallariinae. The superfamily consisting of the tapaculos and the antpittas, if recognised, should therefore be called Rhinocryptoidea Wetmore, 1926 [18","PeriodicalId":38973,"journal":{"name":"Bulletin of the British Ornithologists'' Club","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75537790","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 vocal analysis of the duets of pied boubous Laniarius spp. across eastern Africa is presented, focusing on birds from coastal Somalia south to Mozambique. Based on the presence or absence of certain note types in duets, and variation in their structure across different populations in this region, forms of duet were found to cluster at both larger and smaller spatial scales. Vocal congruence suggests that taxon mossambicus could be conspecific with sublacteus, whereas marked differences between these two and coastal Kenyan birds confirm their previously reported genetic distinctiveness. Patterns of vocal variation broadly align with taxonomic divisions already indicated by genetic data and I integrate these to identify and define the ranges of four distinct groups: the Tropical (major and ambiguus), Ethiopian (aethiopicus), Somali (somaliensis) and East Coast groups (sublacteus, mossambicus and extralimital limpopoensis). Species rank for birds in coastal Kenya under the name Juba Boubou L. somaliensis is also proposed, and vocal data presented here support the findings of Nguembock et al. (2008) and Finch et al.

A review is presented of the seven commonest types of colour aberrations in birds together with suggestions for a standardised universal nomenclature to identify and distinguish these aberrations. These aberrations are: Leucism (congenital absence of melanin-producing cells), Progressive Greying (progressive loss of melanin-producing cells), Albino (total absence of melanin due to lack of the key enzyme), Brown (incompletely coloured melanin), Ino (even less completely coloured melanin), Dilution (altered deposition of melanin) and Melanism (altered distribution of melanin). It is proposed that these terms should be based not only on the resulting plumage but also should distinguish the underlying processes resulting in the aberrant pigmentation. By reviewing previously used terms for colour aberrations, and cross-referencing these with my proposed terminology, errors in earlier names are pointed out, and resulting in a more comprehensive nomenclature for colour aberrations found in wild birds. ‘There has been some confusion in the past in the recording and description of variant plumages … and this paper represents an attempt to clarify some parts of it.’ (Harrison 1963a)","PeriodicalId":38973,"journal":{"name":"Bulletin of the British Ornithologists'' Club","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75128596","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}

Bruce","doi":"10.25226/bboc.v141i3.2021.a12","DOIUrl":"https://doi.org/10.25226/bboc.v141i3.2021.a12","url":null,"abstract":"Platylophus galericulatus (Cuvier, 1816) is a lowland forest bird found in southern Thailand, Peninsular Malaysia, Borneo, Sumatra and Java. Its taxonomic placement has long puzzled systematists (e.g. Amadon 1944, Goodwin 1976). Comparisons of feather tracts and osteology led some to believe that it does not belong to the crows (Clench 1985, Hope 1989). Nevertheless, from the 1940s until recently Platylophus galericulatus was universally classified as a crow (Wolters 1977, Sibley & Monroe 1990, Clements 2007, Dickinson & Christidis 2014, Gill et al. 2021). Recent molecular phylogenetic studies of Corvides have shown that Platylophus galericulatus is neither a true shrike (Laniidae) nor a corvid (Corvidae), and placed the species as the sister of the true shrikes (Jønsson et al. 2008, Aggerbeck et al. 2014, Oliveros et al. 2019); in a polytomy with two major clades that include Corvidae, Laniidae and several other groups (Jønsson et al. 2011); sister to Eurocephalus outside Laniidae and Corvidae (Jønsson et al. 2016, Fuchs et al. 2019); or sister to the birds-of-paradise (Paradisaeidae; Stervander et al. 2020). In rank-based taxonomy, it seems best to place Platylophus galericulatus in its own family. Winkler et al. (2015), Oliveros et al. (2019), Irham & Kurniawan (2020) and Stervander et al. (2020) used the name Platylophidae, but this is a nomen nudum because no such name has been validly introduced. The ‘Platylophidae’ account in Winkler et al. (2015) listed P. galericulatus as its sole species and provided a description that might be construed as a diagnosis. However, these authors did not explicitly indicate the name as intentionally new, and it does not meet ICZN (1999) Art. 16.1. Oliveros et al. (2019), Irham & Kurniawan (2020) and Stervander et al. (2020) merely used the name ‘Platylophidae’ and did not make the name available. The name Lophocittidae was listed by Bock (1994) as a family-group name based on Lophocitteae Kaup, 1855. The latter name is derived from the genus Lophocitta G. R. Gray, 1841, which is a junior synonym of Platylophus Swainson, 1832. However, Kaup’s Lophocitteae and four other new family-group names attributed to Kaup (1855) by Bock (1994) were proposed as ‘Hauptgenera’ (i.e. Cisseae, Cyanocitteae, Cyanocoraceae, Keropieae). Kaup used his ‘Hauptgenera’ as divisions of a subfamily1. Consequently, Lophocitteae is a genus-group name rather than a family-group name. Because no family-group name for P. galericulatus is available, we propose:","PeriodicalId":38973,"journal":{"name":"Bulletin of the British Ornithologists'' Club","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90464764","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}
