“…However, many articles which made use of SABAP2 data (including all the GBIF articles) did not mention this in the title or abstract. 24,25 As a minimum estimate based on the above filters, SABAP2 data alone has contributed to at least 150 peer-reviewed articles, and likely many more.…”

“…Density plots showed the loss of a few large bird species, as well as many small habitat specialists, from pentads classified as urban. An example of the loss of a large-bodied habitat specialist is the Saddle-billed Stork Ephippiorhynchus senegalensis, which is now largely restricted to protected areas across Africa, despite an increase in waterbodies; their preferred habitat (Gula et al 2019). Similarly, we found little evidence that larger-sized raptors, with the exception of the two Milvus kite species, were benefitting from city environments, although McPherson et al (2021) report higher densities of four raptor species in African urban, rather than rural environments, namely the Black Sparrowhawk Accipiter melanoleucus, African Crowned Eagle Stephanoaetus coronatus, Lanner Falcon Falco biarmicus and Peregrine Falcon Falco peregrinus.…”

High human population growth and rapid urbanisation, particularly in Africa, have led to an increased interest in the impacts of this land-use change on bird communities. The African Bird Atlas Project, where species presence lists are collected in pentads, is a valuable source of data with which to explore the extent of these impacts. Here, for the first-time, we test for differences in species richness patterns across 50 matched pentad pairs from sub-Saharan Africa classified as either urban (or semi-urban) and rural. We found that species richness was lowest in pentads classified as urban (mean ± SD: 132 ± 59 species), compared with rural (172 ± 54). However, species richness was similar, compared with rural pentads, when levels of urbanisation were maintained at intermediate levels (semi-urban: 141 ± 69). Surprisingly, we found no significant differences in functional diversity measures between any land-use categories. Across most major dietary guilds (carnivores, herbivores, insectivores, granivores) species richness was lower in urbanised pentads and species were often small. However, the overall biomass of these guilds was similar between urbanised and non-urbanised areas, indicating the presence of common urban exploiter species. This resulted in no differences in functional diversity overall. Pollinators and piscivores showed little difference in metrics between rural and urban pentads. According to a model of the functional traits we consider, an African urban exploiter species is best described by being a scavenger, and less likely to be a habitat specialist, but fill a variety of niches. The urban spatial planning implications are that rare and range-restricted species in proximity to cities, as well as large bird species, will require particular attention and conservation measures as African cities continue to expand. Species richness could be maintained with intermediate levels of urban infrastructure development. Les zones urbaniséessont moins riches en espèces mais conservent une diversité fonctionnelle: un aperçu du projet d'Atlas des oiseaux d'Afrique La forte croissance de la population humaine et l'urbanisation rapide, plus particulièrement en Afrique, ont suscité un intérêt accru sur les impacts de ce changement d'utilisation des terres sur les communautés aviaires. Le projet d'Atlas des oiseaux d'Afrique, qui collecte les données relatives à la présence des espèces au travers de pentades (groupe de cinq unités), est un source précieuse de données permettant d'explorer l'étendue de ces impacts. Au travers de cet article, et pour la première fois, nous testons les différences en termes de richesse d'espèces, au travers de modèles basés sur 50 paires de pentades appariées d'Afrique sub-saharienne et classées comme urbaines (ou semi-urbains) ou rurales. Nous avons estimé que la richesse en espèces était la plus faible dans des pentades de catégorie urbaine (moyenne ± σ: 132 ± 59 espèces) par comparaison aux groupes ruraux (172 ± 54 espèces). Néanmoins, il a été constaté que la richesse en espèce...

“…The articles in this special issue are grouped largely into those focused on waterbirds of inland aquatic environments (de Souza et al 2019;Gula et al 2019;D'Urban Jackson et al 2019;Lee et al 2019;Neb et al 2019) and those focused on waterbirds in coastal and marine environments (Brown et al 2019;Dyer et al 2019;Sherley et al 2019;Tree et al 2019;Vanstreels et al 2019). Among the studies concentrating on inland waterbirds is one of the first attempts to quantify the long-suspected hybridisation between invasive Mallard Duck Anas platyrhynchos and native Yellow-billed Duck A. undulata in South Africa (de Souza et al 2019).…”

“…Empirical data for conservation assessments are desperately lacking and can be incredibly difficult to acquire for wide-ranging species like waterbirds. However, Gula et al (2019) illustrate just how valuable citizen-science platforms can be in this regard. Gula et al (2019) developed an updated distribution map for the Saddle-billed Stork Ephippiorhynchus senegalensis using citizen-science data and clearly reaffirm that protected areas across Africa are critical for the protection of the species.…”
