Breeding ecology of the Chestnut-backed Sparrowlark Eremopterix leucotis in an agroecosystem in the Limpopo province, South Africa
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Derek Engelbrecht --- Department of Biodiversity, South Africa Lucket Dikgale --- Department of Biodiversity, South AfricaWe studied the breeding ecology of the Chestnut-backed Sparrowlark Eremopterix leucotis over three years between 2008 and 2010. The breeding season was bimodal with a main peak in laying in autumn (March–April) and another smaller peak in spring (September–October). Nest... -
Nest and nestling data for Barlow‘s lark, Calendulauda barlowi
Item type: Journal Article • Journal: African Zoology • Authors: Derek Engelbrecht --- School of Molecular and Life Sciences, University of Limpopo, South Africa Johann Lonzer --- Port Nolloth Museum, South AfricaBarlow’s lark is one of southern Africa’s least known lark species. This study is the first to report on the structure and dimensions of this species’ nest and aspects of the nestling period. The ontogenetic development of the nestling is... -
Observations of microtrash ingestion in Cape Vultures in the Eastern Cape, South Africa
Item type: Journal Article • Journal: African Zoology • Authors: Morgan B Pfeiffer --- School of Life Sciences, South Africa Jan A Venter --- School of Natural Resource Management, South Africa Colleen T Downs --- School of Life Sciences, South AfricaIngestion of man-made items by birds can reduce stomach volume and block the digestive track. In southern Africa, microtrash within the regurgitation of Cape Vulture nestlings was last documented in 1983. We present evidence of nestling microtrash ingestion after a... -
Parental care in a sexually monomorphic, ground-nesting passerine, the Pink-billed Lark Spizocorys conirostris (Alaudidae)
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: G Derek Engelbrecht --- Department of Biodiversity, School of Molecular and Life Sciences, South Africa Sean M Marr --- Department of Biodiversity, School of Molecular and Life Sciences, South AfricaWithin the family Alaudidae, most monomorphic species exhibit some degree of biparental care, but direct paternal care in most species is confined to food provisioning to offspring during the nestling period. Uniquely, the genus Spizocorys is the only sexually monomorphic... -
Body condition of Little Egret Egretta garzetta nestlings in relation to hatching order in a southern Tunisian breeding colony
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Amel Neb --- Unité de Recherche “Ecologie de la Faune Terrestre” (UR17ES44) – Faculté des Sciences de Gabès, Tunisia Abdessalem Hammouda --- Unité de Recherche “Ecologie de la Faune Terrestre” (UR17ES44) – Faculté des Sciences de Gabès, Tunisia Slaheddine Selmi --- Unité de Recherche “Ecologie de la Faune Terrestre” (UR17ES44) – Faculté des Sciences de Gabès, TunisiaThe effect of asynchronous hatching on nestling health and condition in ardeids is still in need of empirical evidence from populations living in different environmental conditions. Using morphometric and hematologic data from Little Egret Egretta garzetta nestlings in a Tunisian... -
Sibling competition in the broods of Little Egrets Egretta garzetta in a southern Tunisian breeding colony
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Amel Neb --- , Tunisia Slaheddine Selmi --- , TunisiaAsynchronous hatching is a common hatching pattern in the Little Egret Egretta garzetta, however, its role in maintaining dominance relationships and feeding hierarchy among siblings remains poorly studied. In this study, we investigated this issue using data on feeding and... -
Nestling diet of the Algerian Nuthatch Sitta ledanti, an endemic threatened bird in Babors’ Kabylia region (north-eastern Algeria)
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Mourad Zemouri --- , Algeria Lydia Asloune --- , Algeria Aida Adrar --- , Algeria Abdelouhab Bouchareb --- , Algeria Abdelazize Franck Bougaham --- , AlgeriaThe Algerian Nuthatch is an endemic and protected bird species in Algeria, and its different habitats are threatened by fires and others human actions; the species is therefore considered ‘Endangered’. A faecal samples analysis of the species’ nestlings was done... -
A new record of a chick falling from a nest in Limpopo province, South Africa, adds to the known causes of Hooded Vulture Necrosyrtes monachus mortality
Item type: Journal Article • Journal: African Zoology • Authors: --- , South Africa --- , South Africa --- University Thomas Sankara, Burkina Faso --- , South Africa --- , United StatesFor all species, causes of mortality, both anthropogenic and natural, should be recorded. In Critically Endangered species these records are even more important, owing to their potential impacts on small and/or declining populations. Here we present a case of natural... -
Observations on the breeding biology of D’Arnaud’s Barbet Trachyphonus darnaudii
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Henrik Brumm --- Max Planck Institute for Ornithology, Germany Poyo Makomba --- , Tanzania Wolfgang Goymann --- , TanzaniaBreeding behaviour is a key process for avian fitness and evolution, but the basic natural histories of many species are unknown. We studied the breeding biology of D’Arnaud’s Barbet Trachyphonus darnaudii (family Lybiidae) on the Usangu Plains in southwestern Tanzania...
