Mismatch of research effort and threat in avian conservation biology

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.
