The Whale Diaries.

In an epic 12,000-mile journey south, the Pacific gray whale (Eschrichtius robustus) flees the chilling winter waters of the Artic to the warm and fertile bays of Baja California. Along the way, the whales must endure the fatigue of travel, foraging for amphipods, and the risk of predation.

Ravens mated another species into oblivion, their twisted family tree shows.

Common ravens in California look like other ravens. But their mitochondria contain a genetic jumble. Mitochondria, the tiny power-plant organs within animal cells, carry their own sets of DNA. Animals — humans and ravens included — inherit mitochondrial DNA from mothers. The mitochondrial DNA in ravens revealed a “deep genetic divergence between two different lineages,” Omland said.

Wind Energy vs. Golden Eagles.

The sudden move is important, environmentalists say, because hundreds of birds die at the Altamont each year after getting hit by wind turbine blades, colliding with windmills, or becoming trapped inside them.

Elusive Sierra Nevada Red Fox Captured in Tehama County.

A Sierra Nevada red fox was captured in Tehama County last month by California Department of Fish and Wildlife (CDFW) biologists researching this rare sub-species of red fox.

The 10-pound male fox was captured on national forest land just outside of Lassen Volcanic National Park, near the town of Mineral. The fox was collared and released at the capture location, and CDFW biologists have been impressed by the distances it has regularly been covering despite rough terrain and high elevation.

A Win in Court for California Sea Otters.

PASADENA, Calf. – A big win for southern sea otters, as a federal judge on the 9th Circuit in Pasadena ruled Thursday that the feds do not have to reinstate a failed policy of "No Otter Zones" that had been put in place to protect commercial fishing interests.

Backyard Birder: Birds are beneficial to the garden.

"The ultimate goal of a native garden is to create a place where nature is in balance and the health of each creature in it is supported,” Cook said. “Ideally, we’d like to create robust places that stay healthy with minimal interventions from us.”
