Avian fossils from the Early Miocene Moghra Formation of Egypt
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: N Adam Smith --- National Evolutionary Synthesis Center, USAAvian remains from the Early Miocene (∼17 Ma) Moghra Formation of Egypt include new records of ‘waterbirds’ (storks, herons, pelicans and allies) and a ratite. Only a single avian fossil has been previously reported from Wadi Moghra and, thus, additional... -

Breeding ecology of the Seychelles Black Parrot Coracopsis barklyi
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Anna Reuleaux --- Seychelles Islands Foundation, Seychelles Heather Richards --- Seychelles Islands Foundation, Seychelles Terence Payet --- Seychelles Islands Foundation, Seychelles Pascal Villard --- Seychelles Islands Foundation, Seychelles Matthias Waltert --- Department of Conservation Biology, Germany Nancy Bunbury --- Seychelles Islands Foundation, SeychellesKnowledge of breeding ecology is required for many conservation interventions. The Seychelles Black Parrot Coracopsis barklyi, endemic to the island of Praslin, is vulnerable to extinction. We aimed to improve understanding of C. barklyi breeding ecology to aid conservation planning... -
A comparison of techniques employed in detection of avian malaria infection, South Africa
Item type: Journal Article • Journal: African Zoology • Authors: Sharon Okanga --- Percy FitzPatrick Institute, DST/NRF Centre of Excellence, University of Cape Town, South Africa Graeme S. Cumming --- Percy FitzPatrick Institute, DST/NRF Centre of Excellence, University of Cape Town, South Africa Phillip A. R. Hockey --- Percy FitzPatrick Institute, DST/NRF Centre of Excellence, University of Cape Town, South Africa Mercedes Grome --- Department of Biological Sciences, U.S.A. Jeffrey L. Peters --- Department of Biological Sciences, U.S.A.Avian malaria remains an obscure and mostly unknown avian infection despite the socio-economic threat it poses for poultry industries and its potential to hinder conservation efforts. Therefore, diagnostics for the infection should be expedient, efficient and flexible in applicability. We... -
Temporal and spatial differences in three-egg clutch frequency of the African Black Oystercatcher
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Dane M Paijmans --- Percy FitzPatrick Institute of African Ornithology, DST–NRF Centre of Excellence, South Africa Douglas Loewenthal --- , Peter G Ryan --- Percy FitzPatrick Institute of African Ornithology, DST–NRF Centre of Excellence, South Africa Philip AR Hockey --- ,African Black Oystercatchers Haematopus moquini produce a modal clutch size of two eggs and only rarely lay three eggs. A review of over 4 000 nest records from across their breeding range (dating back to the early 1960s) revealed that... -
Assessing the threat of avian predation on a small viperid snake
Item type: Journal Article • Journal: African Zoology • Authors: Bryan Maritz --- School of Animal, Plant and Environmental Sciences, South Africa Samantha Scott --- School of Animal, Plant and Environmental Sciences, South AfricaPredators are important because they influence survival rates, population density and behaviour of prey species. However, assessing the predation pressure facing a particular species is difficult when that species faces a suite of predators. We aimed to characterize the suite... -
Seasonality, habitat type and locality influenced bird assemblage structure in Nigeria
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Sulaiman I Muhammad --- Department of Biological Sciences, Nigeria Rosli Ramli --- Institute of Biological Sciences, Faculty of Science, Malaysia Amy Y Then --- Institute of Biological Sciences, Faculty of Science, MalaysiaThis is the first report of the avian assemblage in the study area of Dutse, Nigeria. In addition to recording bird species, the effects of season, dominant vegetation structure, locality and anthropogenic activities on bird abundance, species richness and diversity... -
Comparison of physiological responses to high temperatures in juvenile and adult Cape Rockjumpers Chaetops frenatus
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Krista N Oswald --- Department of Zoology, South Africa Alan TK Lee --- Fitzpatrick Institute of African Ornithology, DST/NRF Centre of Excellence, South Africa Ben Smit --- Department of Zoology, South AfricaConcerns about climate change have led to an increase in studies on physiological mechanisms birds possess to cope with increasing temperatures. For range-restricted species such as Cape Rockjumpers Chaetops frenatus, whose population declines are correlated with habitat warming, we identified... -
Taha taha taha: South African bird names across time, language and usage
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Adrian Koopman --- Faculty of Arts and Design, South Africa Eckhart Buchmann --- School of Clinical Medicine,Humans find birds important as food, symbols, competitors, and objects for amusement or study, and give names to different groups or species of bird. However, a single bird may have many names, likely related to different contexts. This article proposes... -

Huddling in the heat? Rarely seen thermoregulatory behaviours as Southern Pied Babblers Turdoides bicolor compete for cool microsites
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Amanda R Bourne --- University of Cape Town, South Africa Camilla Soravia --- The University of Western Australia, AustraliaHuddling is an important thermoregulatory behaviour used by many group-living endotherms to conserve energy during cold weather or periods of food scarcity. It is not typically considered a strategy for keeping cool during hot weather, largely because endotherms produce body... -
