The Cape Parrot Poicephalus robustus is South Africa's only endemic parrot and it is regarded as rare (Downs 2000). Several factors are considered to have caused the decline of the Cape Parrot. These include forest degradation, food and nest-site shortages, low recruitment, removal of birds from the wild for the caged bird trade, and disease (Psittacine Beak and Feather Disease)(Wirminghaus et al. 1999, 2000a).

Snag dynamics and forest structure in Afromontane forests in KwaZulu-Natal, South Africa: implications for the conservation of cavity-nesting avifauna2004 •
Abstract: Little is known about snags in South African indigenous forests. Because of their value to wildlife, we initiated this study to quantify snag characteristics and dynamics. We also investigated forest structure (woody component and snags) and forest use by avian species of conservation concern. We examined tree species composition, abundance and tree size in eight Afromontane mixed Podocarpus forests in KwaZulu-Natal, South Africa. In addition, we investigated the succession of snags at the level of individual trees. Large ...

Factors affecting the decline of the endangered Cape parrot, which is endemic to South Africa, are presented. Its abundance and status were investigated during annual intensive national surveys. The merits of such a census are reported. Presence of birds was unpredictable at forest patches throughout its range. Present distributions in forest fragments reflect past distribution in a larger mosaic of forest patches.
Worldwide, there is concern about the increased prevalence of infectious diseases and their effects on biodiversity. Increasing changes in the environment, particularly changes in climatic conditions as a consequence of anthropogenic-induced climate change, are some of the factors driving this increased disease prevalence. Vertebrate taxa that appear to be most affected by these diseases are amphibians and birds, though this may be a consequence of research effort. Beak and feather disease virus (BFDV) affecting psittacine bird species is the disease of concern here. Data on BFDV incidence in wild, endangered Cape parrots (Poicephalus robustus) were collected opportunistically from 1992 to 2014. Data show that the disease is prevalent naturally in the wild during extreme climatic events, including drought. This stresses the birds, which may result in the expression of pathological symptoms. Juveniles in particular appear to succumb during times of drought. This has conservation implications with the impacts of extreme climatic events associated with anthropogenic-induced climate change.

Methods Artificial nest boxes deployed at Hlabeni Forest, KZN (29 58'S, 29 44'E) were constructed from hollowed logs with mean circumference 105cm, height 60cm, entrance hole diameter 88mm, with wooden bases and tops covered with metal sheeting to prevent rot. They were treated externally with a commercial cleaning fluid (Jeyes FluidTM, Adcock-Ingram, Johannesburg) as a short-term deterrent to honeybees, as recommended by Horsfield (pers. comm.).
