To acquire a 'feel' for the information presented in these volumes it is essential that the user be familiar with the back- ground to the Southern African Bird Atlas. The Atlas of Southern African Birds (Harrison et al. a Harrison et al., b) was used as baseline of existing records. The new records. Box 1. Two early African citizen-science success stories First and Second Southern African Bird Atlas Projects (SABAP1 and 2) SABAP1 and 2.
Western Cape. The GIS shapefile can be downloaded at the link below right click and select "Save link as IBA Shapefile September These practical guidelines have been developed to promote habitat management interventions which will support the eight Fynbos endemic bird species.
They will be of interest to private landowners and various conservation organisations across the Fynbos Biome.
Habitat management guidelines for the endemic birds of the Fynbos Biome. These practical guidelines have been developed to promote waterbird habitat rehabilitation and watercourse conservation and management for farm dams and other agricultural water sources.
Although developed in the Western Cape, they will be of interest to private landowners and various conservation organisations across South Africa. We thank the Table Mountain Fund for funding this project.
Floating Wetlands: Increasing Biodiversity and Cleaning Water. BirdLife South Africa registers, on a regular basis, as an Interested and Affected Party for developments that might affect areas which are important for birds.
Although some Environmental Impact Assessment EIA reports contain sufficient information, most EIA reports do not provide an accurate reflection of the avifauna that occurs in the proposed area of development.
These data sources are also available to the general public.
However, not all EIA practitioners might be aware how to access these data sources. As it is of extreme importance to BirdLife South Africa that these data sources be used to their fullest, a short guideline document has been drawn up and can be downloaded below.

Orange-breasted Waxbill. Depending on the severity of the clinical symptoms observed in chickens, NDV are separated into asymptomatic enteric, lentogenic, mesogenic, viscerotropic velogenic, and neurotropic velogenic pathotypes 1. In addition, avirulent and virulent strains can be distinguished on the basis of the cleavage site sequence of their fusion F protein 1 , one of the most important virulence factors.
Although all NDV strains belong to a single serotype, they are nevertheless genetically highly diverse. In the latter, at least 18 genotypes and multiple subgenotypes have been defined 2 — 4 , but the diversity continues to increase as surveillance improves.
Virtually all domestic and wild bird species are susceptible to infection with NDV 5. Wild waterbirds seem to be the reservoir of avirulent strains, whereas poultry are the most likely reservoir of virulent viruses, but both hosts exchange viruses.
In Israel and Mexico, when captive zoo birds became infected with virulent strains similar to those causing outbreaks in local poultry, spillover from infected domestic birds was suspected but never demonstrated 6 , 7. However, free-living migratory species, such as waterfowls or white storks, may carry virulent NDV strains without obvious contact with poultry 8 — Thus, it could be that wild birds are carriers of virulent strains but transmission routes of virulent NDV strains in particular are not yet fully understood.
Highly similar strains in poultry across West and Central Africa 4 and an increasing number of reports of virulent strains in wild birds on other continents 8 — 10 raise the question of the potential role of wild birds in the spread of virulent NDV in sub-Saharan Africa as well.
