Solving the challenges of monitoring mobile populations: insights from studies of waterbirds in southern Africa
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Hannah L Thomas --- Percy FitzPatrick Institute, DST–NRF Centre of Excellence, South Africa Philip AR Hockey --- Percy FitzPatrick Institute, DST–NRF Centre of Excellence, South Africa Graeme S Cumming --- Percy FitzPatrick Institute, DST–NRF Centre of Excellence, South AfricaHighly mobile species are difficult to monitor. It is often unclear from abundance estimates whether a population is genuinely declining or simply elsewhere. If the spatial and temporal scales of monitoring are inadequate, the data will only be useful if... -
BirdLasser: The influence of a mobile app on a citizen science project
Item type: Journal Article • Journal: African Zoology • Authors: Alan Tristram Kenneth Lee --- , South Africa Henk Nel --- , South AfricaIn recent decades, people across the world have adopted ‘smart-phones’ and their technology. Software applications on these devices have become diverse in their functionality and easy to use. Citizen science projects that try to mobilise data collection from people from... -
COVID-19 and citizen science: lessons learned from southern Africa
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Sanjo Rose --- , South Africa Jessleena Suri --- , South Africa Michael Brooks --- , South Africa Peter G Ryan --- , South AfricaThe COVID-19 lockdown has had a marked effect on citizen science projects, such as the Southern African Bird Atlas Project, SABAP2. With their mobility severely constrained, most citizen scientists in South Africa were not able to submit full protocol lists... -
South African raptors in urban landscapes: a review
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Shane C McPherson --- , South Africa Petra Sumasgutner --- , Austria Colleen T Downs --- , South AfricaGlobally, but especially in Africa, increasing human populations and anthropogenic land-use change are generally affecting diversity negatively. Urban environments in southern Africa typically comprise a mosaic landscape of anthropogenic infrastructure with some green spaces. These urban cities have a range... -
Urban areas have lower species richness, but maintain functional diversity: insights from the African Bird Atlas Project
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Alan Tristram Kenneth Lee --- , South Africa Ulf Ottosson --- , Nigeria Colin Jackson --- , Kenya Sidney Shema --- , Kenya Chevonne Reynolds --- , South AfricaHigh 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... -
The effects of habitat loss and fragmentation on updated estimates of the population of the Agulhas Long-billed Lark Certhilauda brevirostris, a South African endemic
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Steven W Evans --- , South AfricaThe Agulhas Long-billed Lark Certhilauda brevirostris is a South African endemic and is restricted to the fynbos habitat of the Agulhas Plain in the southwestern corner of South Africa. The 1990, 2014, and 2018 land use land cover (LULC) databases... -
Identification of the landscape and bioclimatic characteristics that contribute to maintaining the allopatric distribution ranges of the Northern Black Korhaan Afrotis afraoides and the Southern Black Korhaan Afrotis afra
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Steven W Evans --- , South AfricaThe Northern Black Korhaan Afrotis afraoides and the Southern Black Korhaan Afrotis afra were previously considered conspecific, but were subsequently separated based on habitat, plumage, displays and vocalisations of the males and genetic differences. The Northern Black Korhaan is endemic... -
The African Bird Atlas Project: a description of the project and BirdMap data-collection protocol
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Michael Brooks --- University of Cape Town, South Africa Sanjo Rose --- University of Cape Town, South Africa Res Altwegg --- University of Cape Town, South Africa Alan TK Lee --- University of Cape Town, South Africa Henk Nel --- , South Africa Ulf Ottosson --- A.P.

Leventis Ornithological Research Institute, Nigeria Les G Underhill --- University of Cape Town, South Africa Robert L Thomson --- University of Cape Town, South AfricaThe African Bird Atlas Project (ABAP) is a citizen-science bird-monitoring programme that relies on a robust, repeatable protocol (BirdMap) and allows insights into the distributions of African birds and their conservation. The protocol involves collecting bird lists within spatial sampling... -
The effects of habitat loss and fragmentation on the relative abundance and conservation of Ludwig’s Bustard Neotis ludwigii in South Africa
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Steven W Evans --- North-West University, South AfricaLudwig’s Bustard Neotis ludwigii is near-endemic to the semi-arid shrublands of southwestern southern Africa and is listed as Endangered. The primary threat to this species is collisions with overhead powerlines; however, loss and fragmentation of its habitat may contribute to... -
A conservation assessment of birds in the Karoo region of South Africa: densities, populations, ranges, and trend estimates
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Alan TK Lee --- University of Cape Town, South Africa Dale R Wright --- RMIT University, AustraliaThe Karoo region of South Africa, which includes the Succulent and Nama Karoo biomes, supports a unique avian fauna, with ten bird species occurring exclusively in this arid-zone region and many others exhibiting a strong preference for this habitat. To... -
Range expansion of African Red-eyed Bulbul Pycnonotus nigricans in western South Africa
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Itxaso Quintana --- Biodiversity and Development Institute, South Africa Salome Willemse --- Biodiversity and Development Institute, South Africa Karis Daniel --- Biodiversity and Development Institute, South Africa Trevor Hardaker --- , South Africa Les G Underhill --- Biodiversity and Development Institute, South AfricaData from five citizen science projects were used to document shifting ranges of two species of bulbul in South Africa. We show that African Red-eyed Bulbuls Pycnonotus nigricans steadily replaced Cape Bulbuls P. capensis in the lower Olifants River valley,...
