  1. Nest-site partitioning in a strandveld shrubland bird community

    Nest-site partitioning in a strandveld shrubland bird community

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    Nest-site selection may vary adaptively among co-existing species as a result of competitive interactions among the species or in response to density-dependent nest predation. We examined nest-site characteristics and degree of partitioning among 14 co-existing bird species breeding in dwarf...
  2. The influence of nest-site characteristics on the nesting success of the Karoo Prinia (<em>Prinia maculosa</em>)

    The influence of nest-site characteristics on the nesting success of the Karoo Prinia (<em>Prinia maculosa</em>)

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    Choice of nest site has important consequences for nest survival. We examined nest-site characteristics relative to nest success in Karoo Prinias breeding in coastal dwarf shrubland, where high nest predation is the main cause of nest failure. Initially, we compared...
  3. Current conservation status of the Blue Swallow <em>Hirundo atrocaerulea</em> Sundevall 1850 in Africa

    Current conservation status of the Blue Swallow <em>Hirundo atrocaerulea</em> Sundevall 1850 in Africa

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    The global Blue Swallow Hirundo atrocaerulea was classified as Vulnerable in 2010 on account of its small and rapidly declining population estimated at less than 1 500 pairs. We undertook this study to gain a better understanding of the current...
  4. Status of the population of Karamoja Apalis <em>Apalis karamojae</em> in north-eastern Uganda

    Status of the population of Karamoja Apalis <em>Apalis karamojae</em> in north-eastern Uganda

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    The distribution of the Karamoja Apalis Apalis karamojae, an East African endemic, has been sparsely documented in Uganda. In October 2011, a survey of the species was carried out near Iriiri in north-eastern Uganda. The main aim was to find...
  5. Densities and population sizes of raptors in Uganda’s conservation areas

    Densities and population sizes of raptors in Uganda’s conservation areas

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    Projected increases in Africa's human population over the next 40 years point to further, large-scale conversion of natural habitats into farmland, with far-reaching consequences for raptor species, some of which are now largely restricted to protected areas (PAs). To assess...
