Nectar feeding by weavers (Ploceidae) and their role as pollinators
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Adrian JFK Craig --- Department of Zoology and Entomology, South AfricaReviews of nectar-feeding by birds initially focused on specialist nectarivores and ignored the role that more generalist feeders may play in plant pollination. Recent work has emphasised the range of bird species, both specialist and opportunistic, that feed on nectar... -
Crop damage by granivorous birds despite protection efforts by human bird scarers in a sorghum field in western Kenya
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Matthew Hiron --- Department of Ecology, Sweden Diana Rubene --- Department of Ecology, Sweden Collins K Mweresa --- International Centre of Insect Physiology and Ecology, Kenya Yvonne UO Ajamma --- International Centre of Insect Physiology and Ecology, Kenya Eunice A Owino --- International Centre of Insect Physiology and Ecology, Kenya Matthew Low --- Department of Ecology, SwedenCereal crop damage from granivorous birds poses a serious food security problem for subsistence farmers in sub-Saharan Africa. In this region, farmers may rely on human ‘bird scarers’ to limit crop damage. Here we report feeding behaviour and crop damage... -
Birds adopting weaver nests for breeding in Africa
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: H Dieter Oschadleus --- Animal Demography Unit, Department of Biological Sciences, South AfricaWeavers build domed, long-lasting nests that may also be adopted by other species for breeding, probably reducing the energetic costs of nest building to varying degrees. In an extensive literature search, 57 species were found to have at least one... -
Behavioural analysis of Village Weavers Ploceus cucullatus in an Ethiopian breeding colony during incubation: 1. Females
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Bobby Habig --- Department of Biology, Queens College, USA Khaleda Khan --- Department of Biology, Queens College, USA David C Lahti --- Department of Biology, Queens College, USAWe used video recordings to perform a behavioural analysis of a Village Weaver Ploceus cucullatus colony in Awash National Park, Ethiopia. We focused specifically on female behaviour during the pair-formation, egg-laying and early-incubation phases of the nesting cycle. A factor... -
Behavioural analysis of Village Weavers Ploceus cucullatus in an Ethiopian breeding colony during early incubation: 2. Males
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Khaleda Khan --- Department of Biology, Queens College, USA Bobby Habig --- Department of Biology, Queens College, USA David C Lahti --- Department of Biology, Queens College, USAWe observed a colony of Village Weavers Ploceus cucullatus in Ethiopia at the height of the breeding season to assess variation and relationships amongst male behaviours. Individuals spent most of their time on behaviours functioning in acquiring and retaining mates,... -
Variation in colony sizes of weavers from a citizen science project
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Hans-Dieter Oschadleus --- , South AfricaThe project PHOWN (PHOtos of Weaver Nests) is a citizen science project that collects breeding distributions and colony sizes of weaverbirds (Ploceidae) globally. PHOWN began in mid-2010 and has collected nearly 30 000 records in 9.5 years. This paper provides... -
Sunning in Yellow Bishops Euplectes capensis
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: H Dieter Oschadleus --- University of KwaZulu-Natal, South Africa Philipp H Boersch-Supan --- , United KingdomTwo photographic records of a Yellow Bishop Euplectes capensis apparently sunning, at the West Coast National Park, South Africa, are described. There are very few records of sunning in weavers, and this is the first record for this species. -
Plumage dimorphism and moult patterns of weaverbirds – a review
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: H-Dieter Oschadleus --- University of KwaZulu-Natal, South Africa Staffan Andersson --- University of Gothenburg, SwedenThe colourful plumages of weaverbirds (family Ploceidae, with 118 species recognised) provide a well-known and in part iconic showcase of sexual selection, with widespread sexual dimorphism (93 species) as well as seasonal dimorphism (62 species). The tremendous diversity in both... -
New records of Fox’s Weaver Ploceus spekeoides significantly disrupt perceptions concerning its conservation status
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Jonathan Onongo --- , Uganda Achilles Byaruhanga --- , Uganda Dianah W Nalwanga --- , Uganda Micheal Kibuule --- , Uganda Nigel J Collar --- , United Kingdom Simon Valle --- , United StatesIUCN Red List categorisation helps prioritise species conservation efforts. Fox’s Weaver Ploceus spekeoides is a little-known passerine endemic to eastern Uganda and categorised as Near Threatened. Historical records (1913–1996) of this bird span nine sub-counties in the country, but more...
