Summary:
A study of DNA from the threatened California gnatcatcher and the abundant Baja (Mexico) gnatcatcher has shown no differences that would place the two birds in different subspecies. Therefore, destroying the California bird's habitat through development will not threaten the species, or any subspecies, as a whole, said University of Minnesota evolutionary biologist Robert Zink, who headed the study. But, said Zink, the finding points up the risk of trying to preserve habitat based on the status of only one species.
