Abstract We present a complete, time-scaled, evolutionary tree of the world’s bird species. This unites phylogenetic estimates for 9,239 species from 262 studies published between 1990 and 2024, using Open Tree synthesis algorithm. The remaining are placed in based on curated taxonomic information. tips this complete aligned to Clements Taxonomy used by eBird other resources, cross-mapped systems including Life (Open Tree), National Center Biotechnology Information (NCBI), Global Biodiversity Facility (GBIF). total number named varies 10,824 11,017 across taxonomy versions we applied (v2021, v2022 v2023). share trees each version. procedure, software data-stores generate public reproducible. presented here is Aves v1.2 can be easily updated with new information as published. demonstrate types large scale analyses data resource enables linking geographic phylogeny calculate regional diversity birds world. will release translation tables annually. procedure describe developing any group interest. Significance statement Birds charismatic - well loved, highly studied. Many phylogenies elucidating avian relationships every year. have united hundreds create all birds. While variety resources aggregate huge collections trait, behavior location birds, previously barriers these history limited opportunities do exciting analyses. bridged that gap, developed system allows us update our understanding evolution generated. workflow needed group.

AbstractThe Karoo region of South Africa, which includes the Succulent and Nama biomes, supports a unique avian fauna, with ten bird species occurring exclusively in this arid-zone many others exhibiting strong preference for habitat. To better determine conservation status these birds, we conducted point counts to estimate population densities African 2017 2018. We also used data Bird Atlas Projects (SABAP2) species' ranges trends. Although are naturally low most species, their very large, reporting-rate trends appear stable species. Our analysis reveals that none currently serious concern. However, Red Lark Calendulauda burra Sclater's Spizocorys sclateri should be considered regionally Near Threatened as they habitat specialists inferred declining populations not protected within any designated areas. Given rapid transformation landscapes linked mining alternative energy developments underway Karoo, combined poor representation areas, it is imperative special attention paid endemic appropriate mitigation measures taken by developers.Évaluation de la des oiseaux région du en Afrique Sud: estimatives densités, abondances, et aires repartitionLe qui comprend les biomes abrite une avifaune unique, avec dix espèces présentes exclusivement dans cette zone aride nombreuses autres nette préférence pour cet Afin mieux déterminer le statut ces oiseaux, nous avons mené comptages par points d'écoute estimer densités sud-africain au cours l'année 2017–2018.

Genetic isolation and morphological differentiation are two important factors in the speciation process that not always act concert. A rapid change a lineage can hide its close relationship to another lineage, while slight between taxa give appearance of closer than is actually case. The Dollarbird (Eurystomus orientalis) Azure Roller azureus) such an example. Today unanimously considered constitute distinct species, but recent genetic study it has been shown latter taxon, despite being larger having distinctly different coloration, phylogenetically nested within former. Its precise placement this complex determined, however. In study, we investigate phylogenetic relationships Dollarbird/Azure complex. We estimate divergence times infer using sequence data from 6,475 genome-wide intronic regions, as well complete mitochondrial genomes, both concatenation multispecies coalescence approaches. find there several examples discrepancies differentiation. currently divided into nine twelve subspecies. Some these subspecies poorly differentiated, whereas others morphologically more clearly discernable. Our suggest consist at least seven lineages do entirely match variation group. For instance, our results show solomonensis Solomon Islands, very similar geographically closest neighbors, fact highly became isolated 700,000 years ago. contrast, Roller, which treated forms slightly younger sister group clade with Australian New Guinean Dollarbirds. also deep split Dollarbirds on Asian mainland. This stands contrast apparent clinal reported for birds support presence genetically Wallacea region. region previously recognized subspecies, connectens, placed synonymy other thus odds current division species. Given species status azureus undisputed, clear separation suggests taxon warrants status. Based observed little doubt even should regarded require further examination.

Abstract Larks (Alaudidae) constitute one of the avian families best adapted to xeric environments, having colonized a wide suite open habitats including deserts. Although their highest diversity is in Africa, larks occur on all nonpolar continents. We tested whether exhibit exceptional and/or correlated shifts tempos speciation and ecological trait diversification face space. employed near-complete phylogeny morphological dataset several recently recognized species. found homogeneity dynamics across family evidence for diversity-dependent slowdown cladogenesis, which indicates that Alaudidae may approach ‘ecological limit’. did not observe an early burst phenotypic diversification, as would be expected ‘classic’ adaptive radiation. Our findings suggest morphology shows high level evolutionary conservatism overall lack ecomorphological convergence: variables (diet habitat)—which by contrast display higher lability—explain little shape/size variation except beak shape. Both adaptation aridity dietary transitions have evolved independently multiple lineages subfamilies. This study supports idea continental radiations reach equilibrium faster than those tropical forests, due differences opportunities.
