One hundred and two species of birds that are thought to be vulnerable in South Africa have been reported from or are likely to occur within the Kruger National Park. These species are considered in relation to their distribution and status in South Africa and the neigbouring countries. The following are suggested as conservation priorities for birds in the Park: 1. Re-establish the extinct Yellow-billed Oxpecker. 2. Investigate the suite of large carnivorous and scavenging birds that have declined over much of their range elsewhere in South Africa. 3. Investigate the species associated with riparian and wetland habitats in the Park. 4. Investigate the tropical species that are confined to the Park within South Africa.

Avian declines and extinctions are a worldwide concern. Conservation priorities for birds should target threatened taxa (taxonomic targets) and regions with high levels of species richness and endemism (geographical targets). Does published research on bird conservation reflect the global taxonomic and geographic priorities? We surveyed six years (2000–2005) of six international conservation journals, and analyzed all articles on birds. Attention indexes were calculated for orders, threatened species, and biogeographic realms. We also examined how well research from tropical nations (with high levels of richness and endemism) are represented in the international literature. Results show that Struthioniformes is the order that has the highest attention (0.54), mostly because this order has relatively few species, and the lowest attention was recorded for Coliiformes (0.00). For some orders (Anseriformes, Apodiformes, Caprimulgiformes, Coraciiformes, Cuculiformes, Gaviiformes, Pelecaniformes, Phoenicopteriformes, Podicipediformes, Struthioniformes, Tinamiformes and Trogoniformes), most of the published research focuses on non-threatened species. The Nearctic and Palearctic are the biogeographic realms that receive most attention by avian conservationists. However, the Neotropical, Afrotropical, and Indomalayan are the regions with higher species diversity. Eighty-four countries contributed articles, but the majority of bird conservation research is conducted by North American and western European researchers. There is urgent need for capacity building in tropical developing nations. Birds are seriously threatened and are rapidly declining worldwide. However, bird conservation is still misplacing its focus in lower-biodiversity regions and for some orders focusing in non-threatened species. If such trends are not changed, the consequences for the persistence of birds worldwide may be dire.

SummaryBecause museum scientists and conservationists are natural allies in the struggle to preserve biodiversity, conflict over the legality, morality, and value of collecting scientific specimens is counterproductive. Modern bird specimens contain a variety of data, summarized briefly herein, that are applied to numerous questions concerning the biology of birds, many of which have direct and often critical relevance to conservation. In particular, continued collecting of specimens has been shown to be critical in determining species-level classification in birds; unless species limits are established correctly, conservation priorities cannot be established reliably. Objections to collecting specimens are summarized and discussed. Calculations are presented to show that the effect of collecting specimens on most bird populations is insignificant. Moral objections t o collecting specimens seem to reflect a lack of awareness of the extent and causes of natural mortality, as well as a failure to recognize the magnitude of unintentional mortality inflicted on bird populations by routine human activities. The reason why more specimens are needed than currently exist in museum collections is that most existing specimens lack the data needed for most kinds of modern analyses, and even common species are represented by inadequate samples for research. Reasons are given for why equivalent data cannot be obtained solely from living birds that are subsequently released. Objecting to collecting specimens because it sets a bad example for developing countries trying to establish an environmental ethic is counterproductive in that it draws attention away from the fundamental units of concern for conservation biology: the population, and the habitat that supports it. Biological specimens differ from some other scientific specimens (e.g. archaeological) in that they are renewable resources whose removal does not deplete a country's national heritage. Misconceptions about museum scientists and their motives are discussed. Regarding collecting permits, recommendations are presented concerning (1) numbers of specimens, (2) percentage of specimens left in the host country, (3) species composition, (4) deposition of specimens, and (5) processing permit applications. Regulating agencies are often overly enthusiastic i n restricting scientific collecting, which is the only kind of mortality that is so highly controlled and yet from which bird species might derive benefit, whereas the same or sister agencies often permit and even encourage activities that are responsible for massive mortality in bird populations. Given that (1) the goal of scientists, conservation agencies, and governments is protection of populations, not individual birds; (2) scientific collecting has no measurable impact on the vast majority of bird populations; (3) scientific specimens represent an important source of information on bird biology and conservation; and (4) existing scientific collections are largely inadequate for answering many questions that could be answered with greater numerical, seasonal, or geographic representation, then it follows that continued scientific collecting will benefit ornithology and conservation and should, therefore, be encouraged by conservation and government agencies.
