The March issue of Birding features the work of Kevin Omland, an associate professor of biology.
The author, Paul Hess writes that, Omland and his colleagues, “take an opposite view from several papers that recommend splitting the Common Raven into two species.”
The new study demonstrates a need for multiple criteria — not only genetic, but also morphological, behavioral and ecological to judge whether a population deserves full-species status.
