[Sweden] Genetic tests of North American birds show what may be 15 new species including ravens and owls — look alikes that do not interbreed and have wrongly had the same name for centuries, scientists said on Sunday. If the findings from a study of birds’ DNA genetic “barcodes” in the United States and Canada hold true around the world, there might be more than 1,000 new species of birds on top of 10,000 identified so far, they said. A parallel study of South American bats in Guyana also showed six new species among 87 surveyed, hinting that human studies of the defining characteristics of species may have been too superficial to tell almost identical types apart.
