Most new species are actually the result of 'splits', when a singular species is separated into two or more distinct taxa thanks (usually) to DNA evidence and vocalizations. This was the case with the Red Crossbill population found in the isolated hills of southern Idaho. Now considered a new species, this group of sedentary Red Crossbills has been reproductively isolated from the rest of it's usually nomadic brethren.

Recently a new species was also discovered in southwest Africa. The olive-backed forest robin was given it's scientific name, Stiphrornis pyrrholaemus, by Smithsonian naturalist Brian Schmidt. In Greek, the name literally translates to "stout bird that bears a flame-colored throat". Pretty creative, huh?
