  3. Timing of primary wing moult in sexually dimorphic passerines from the Western Cape, South Africa

    Timing of primary wing moult in sexually dimorphic passerines from the Western Cape, South Africa

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    SAFRING ringing data was used to investigate the differences in the timing and duration of primary wing moult between males and females of sexually dimorphic passerines from the Western Cape, South Africa. In the sunbirds, weavers and canaries that were...
  4. Regional patterns in moult and sexual dimorphism of adult Southern Red Bishops <em>Euplectes orix</em> in southern Africa

    Regional patterns in moult and sexual dimorphism of adult Southern Red Bishops <em>Euplectes orix</em> in southern Africa

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    Using the SAFRING database and the Underhill-Zucchini model of primary moult, we analysed the timing of wing moult in Southern Red Bishops Euplectes orix in relation to sex and geographical region. Birds from the winter rainfall region in the south-western...
  5. Adaptations in primary wing moult of southern African Viduidae and their hosts (Estrildidae)

    Adaptations in primary wing moult of southern African Viduidae and their hosts (Estrildidae)

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    Primary wing moult patterns in southern African brood-parasitic viduines were compared with those of their estrildid hosts. We searched for similarities in the timing and duration of moult within these closely related species potentially arising from their linked breeding biology...

    Longevity of the Seychelles Fody <em>Foudia sechellarum</em>

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    The Seychelles Fody Foudia sechellarum, which occurs on six islands in the Seychelles, has been well ringed over several decades in order to obtain population estimates for the species, and morphological descriptions and measurements. Annual survival estimates for the species...

    Sociable Weaver biometrics and primary moult

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    The biometric and primary moult data housed at the South African Bird Ringing Unit (SAFRING) were analysed for the Sociable Weaver Philetairus socius. The average body mass and wing length was 27.9g (SD = 2.2) and 74.1mm (SD = 2.5),...
