A vast mountainous region glimpsed by generations of Californians mainly through bug-pocked windshields on Interstate 5 was preserved Thursday in what conservationists say is the largest, most ecologically crucial acquisition of public land in state history. The deal saves from development more than 240,000 acres of the Tejon Ranch - a ruggedly diverse stretch of grassland, forest and oak woodland just north of Los Angeles. It is, in reality, a unique ecosystem eight times the size of San Francisco. |

Experts identify molecule that reacts to magnetic field
Rick Weiss, Washington Post
Flying with a chemical compass? Four decades after scientists showed that migratory birds use Earth's magnetic field to orient themselves during their seasonal journeys, researchers have at last found a molecular mechanism that may explain how they do it. If the hypothesis is true, the planet's magnetic field lines - which arch around Earth from north to south - may be plainly visible to birds, like the dashed line in the middle of a road.

The Case of the American Kestrel Ernesto Ruelas Inzunza - The answer is a sound yes. Available data on kestrel populations comes from several different data sources: migration counts, the Breeding Bird Survey (BBS), Christmas Bird Count (CBC), and also from regional nest box programs. Because the American Kestrel is a partial migrant, a species whose winter range largely overlaps its breeding range and which also falls largely within the well-sampled area of southern Canada and the United States, using CBC data to support these statements has considerable value. |

Sacramento – An alliance of 16 leading environmental, agricultural and government agencies and organizations have finalized an agreement that charts a cooperative approach for restoring the rapidly declining Tricolored Blackbirds that are an important part of California’s native wildlife. The agreement, hammered out over 18 months, pledges diverse interests to work together as opposed to seeking additional regulatory protection for this species through the Endangered Species Act.
Among the parties to the agreement: Audubon California, California Farm Bureau, California Cattlemen’s Association, California Department of Fish and Game, Sustainable Conservation, University of California, and U.S. Fish and Wildlife Service. |

Associated Press According to the U.S. Fish & Wildlife Service, which tracks wildlife recreation, birdwatching is now a hobby of 47.8 million Americans, with "wildlife watching" up 8 percent from 2000 to 2006. The birdwatching trend comes as both hunting and fishing declined in popularity, by 4 percent and 12 percent, respectively, over the same period. |

A premier online birding program has been developed for you in California! Audubon California, PRBO Conservation Science, and Cornell Lab of Ornithology have partnered to create this eBird site specific to California, and your participation will help us learn more about bird distribution and abundance throughout the state. With your help, we can begin to complete the picture of how birds are distributed across the diverse California landscape and track what changes may be occurring in the future. Choose a California Important Bird Area or Birding Hot Spot and enter your data! Visit Audubon California's IBA Program Website for more information.

Sacramento, CA – Audubon California today applauded Gov. Schwarzenegger’s decision to sign AB 821, which will help the continued recovery of the California Condor by banning the use of lead ammunition from areas inhabited by the endangered species.
“This is a great day for the California Condor and the State of California,” said Glenn Olson, executive director of Audubon California. “I would like to commend Governor Schwarzenegger for signing the Ridley-Tree Condor Conservation Act and again putting our state at the forefront on wildlife protection.” |
