400 New Species Globally

First-ever illustrated global bird classification reveals 400 new species

Researchers spent four years gathering live footage and studying specimens in captivity around the planet.  They assigned scores to five characteristics:  measurements, songs, plumage, behaviors, and geographical relationships with one another. The scores on these characteristics led the researchers to believe that 462 species that were subspecies are actually new species.  Apparently with this new classification, the scientists believe that over one-quarter of the new species are threatened.
