  1. Fifteen years of annual Cape Parrot <em>Poicephalus robustus</em> censuses: current population trends and conservation contributions

    Fifteen years of annual Cape Parrot <em>Poicephalus robustus</em> censuses: current population trends and conservation contributions

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    The Cape Parrot Poicephalus robustus is endemic to South Africa and numbers have reportedly declined since the early 1900s. It is a forest specialist and food nomadic, moving between patches depending on fruit availability. This makes it difficult to estimate...
  2. Public surveys of rose-ringed parakeets, <em>Psittacula krameri</em>, in the Durban Metropolitan area, South Africa

    Public surveys of rose-ringed parakeets, <em>Psittacula krameri</em>, in the Durban Metropolitan area, South Africa

    Item type: Journal Article • Journal: African Zoology
    Globally, the rose-ringed parakeet, Psittacula krameri, is the most invasive parrot species and became established in South Africa in the 1970s. The aim of this survey was to determine the current occurrence and distribution of rose-ringed parakeets in the greater...
  3. Digestive efficiency of indigenous and invasive avian species fed fruit of invasive alien plants in South Africa

    Digestive efficiency of indigenous and invasive avian species fed fruit of invasive alien plants in South Africa

    Item type: Journal Article • Journal: African Zoology
    Many highly invasive plant species produce fleshy fruit that are consumed and dispersed by frugivorous birds. However, little is known about assimilation efficiency of invasive fruit by indigenous and invasive avian species. We investigated whether indigenous Knysna (Tauraco corythaix) and...
  4. Black Sparrowhawk <em>Accipiter melanoleucus</em> breeding behaviour and reproductive success in KwaZulu-Natal, South Africa

    Black Sparrowhawk <em>Accipiter melanoleucus</em> breeding behaviour and reproductive success in KwaZulu-Natal, South Africa

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    Black Sparrowhawk Accipiter melanoleucus breeding behaviour and nest success was determined using camera traps and field observations in KwaZulu-Natal, South Africa. Nest preparation was done predominantly by the male with incubation and brooding largely performed by the female. Brooding duration...
  5. Biology of the redspotted tonguesole <em>Cynoglossus zanzibarensis</em> (Pleuronectiformes: Cynoglossidae) on the Agulhas Bank, South Africa

    Biology of the redspotted tonguesole <em>Cynoglossus zanzibarensis</em> (Pleuronectiformes: Cynoglossidae) on the Agulhas Bank, South Africa

    Item type: Journal Article • Journal: South African Journal of Marine Science
    The biology of the redspotted tonguesole Cynoglossus zanzibarensis, a common African cynoglossid inhabiting the Agulhas Bank, South Africa, is described. Growth studies based on sectioned sagittal otoliths revealed that C. zanzibarensis is relatively fast-growing and long-lived, attaining ages >8 years...
