Birdlife’s recent assessment of 350 newly recognised bird species, on behalf of the IUCN Red List, has found that 25 percent of these species are at risk of extinction. Around 13 percent of all known bird species are considered to be at risk, showing that the conservation of these newly recognised species needs to be prioritised.
This recent study focussed on non-passerine birds, such as birds of prey, owls, seabirds and waterbirds. There are 4,472 non-passerine birds known to science, of which 361 were found to be distinct species during this recent assessment. The identification of these new non-passerines shows that previous species counts have underestimated the true diversity of this avian group by around 10 percent.
One finding of the study was that an ostrich subspecies, the Somali ostrich, is in fact a distinct species and has now been classified as Vulnerable. Andy Symes, BirdLife’s Global Species Officer, said, “This species highlights both the need for improved knowledge of the world’s birds and the need for conservation action in some of the most challenging parts of the globe.” It is hoped that the early recognition of these threatened species will provoke action to ensure their future survival.
Various species have also been reassessed to determine whether their Red List classification is currently correct. The population size of many species has dramatically decreased, leading to reclassification. In some species, such as the lammergeier, it was found that the population is becoming larger in certain areas but is declining in others.
The importance of bird hotspots was also highlighted during the assessment, especially those that are home to many endemic species. These habitats, along with the bird species that live within them, are in desperate need of conservation action to ensure their future survival. Dr Stuart Butchart, BirdLife’s Head of Science, said, “The IUCN Red List is crucial not only for helping to identify those species needing targeted recovery efforts, but also for focussing the conservation agenda by identifying the key sites and habitats that need to be saved, including Important Bird and Biodiversity Areas.”
