One tenth of bird species flying under the conservation radar, according to BirdLife International’s recent assessment of globally threatened birds. More than 350 newly recognised bird species have been assessed by BirdLife International for the first time on behalf of The IUCN Red List of Threatened Species™. Worryingly, more than 25% of these newly recognised birds have been listed as threatened on The IUCN Red List – compared with 13% of all birds – making them urgent priorities for conservation action.
The first of a two-part comprehensive taxonomic review has focussed on non-passerine birds – such as birds of prey, seabirds, waterbirds and owls – and has led to the recognition of 361 new species, that were previously treated as ‘races’ of other forms. The new total of 4,472 non-passerines implies that previous classifications have undersold avian diversity at the species level by more than 10%.
“Put another way, one tenth of the world’s bird species have been flying below the conservation radar”, said Dr Stuart Butchart, BirdLife’s Head of Science.
Species such as Belem Curassow Crax pinima from Brazil and Desertas Petrel Pterodroma deserta from Madeira have been listed as Globally Threatened. In the case of the Blue-bearded Helmetcrest Oxypogon cyanolaemus, a beautiful hummingbird from Colombia, it may already be too late, as the species has not been seen for nearly 70 years.
The new criteria for determining which taxa qualify as species have created a level playing field, by which all bird species can be assessed equally. They also bring an added precision to help us shine a light on the places most important for birds, nature and people – the areas of the planet that we need to urgently protect and save.
