New bird, bat species revealed by extensive DNA barcode studies
...ournal Molecular Ecology Notes, they report having assembled a genetic portrait of birdlife in the U.S. and Canada, and announce the startling discovery of 15 new genetically distinct species, nearly indistinguishable to human eyes and ears and consequently overlooked in centuries of bird studies.
