Satellite tracking has shown a polar bear swimming at least 46 miles in just one day, the first conclusive proof that the bears can cover such distances in the water. The collared bear entered the water from the east side of the Norwegian Arctic island of Spitsbergen early July 20, swam northeast and reemerged on Edgeoya island July 21, the Norwegian Polar Institute reported Friday.

A 195-pound sea lion was recovering Monday after swimming nearly five miles up the San Diego Creek channel, reaching the unlikely destination of the Irvine Civic Center before calling it a day. The mammal, a 3- or 4-year-old female dubbed Irvine, was expected to be released back into the ocean Wednesday after resting at the Pacific Marine Mammal Center in Laguna Beach.

University of California scientists have wired a forest in the San Jacinto Mountains with high-tech gadgets for a close-up study of nature. About two dozen remotely operated cameras -- including one slung from cables and operable via Internet connection -- zoom in on feeding sparrows, nesting bluebirds, grazing deer and other wildlife at the James Reserve near Idyllwild. The equipment enables scientists to study previously unobserved phenomena, such as animal behavior during weather changes.

A 12-year-old girl who was abducted and beaten by seven men trying to force her into a marriage was found being guarded by three lions who apparently chased off her captors, a policeman said. She was beaten repeatedly before she was found June 9 by police and relatives on the outskirts of Bita Genet, about 350 miles southwest of Addis Ababa, the capital. She had been guarded by the lions for about half a day, Sgt. Wondimu Wedajo said.

British researchers have shown that honeybees are able to read the directional signals conveyed by foragers in the famous figure-eight "waggle dance." Zoologist Karl von Frisch won the 1973 Nobel Prize in Medicine or Physiology for showing that the dance contained directions to food sources. Researchers at Rothamsted Research in Britain exposed bees to a forager's dance, then moved them to a different location before releasing them.

Mice forced to breathe hydrogen sulfide -- best known for its rotten egg smell -- go into a kind of suspended animation, U.S. researchers said Thursday. The finding may help save human lives. Although hydrogen sulfide gas is toxic in high doses, it may activate some of the mechanisms that cause some animals to go into hibernation, the researchers wrote in this week's issue of the journal Science.

An early wake-up call for grizzly bears in southwest Canada may have endangered sows and their cubs. Unseasonably warm weather turned dens soggy in January, prompting many female grizzlies to emerge months earlier than usual, says Jim Clark, a wildlife technician with the Alberta government. Wildlife officials fear that as the sows left their dens, they may have abandoned newborn cubs that are too young to forage for food.

There are one to three eggs in the nest with the posh Manhattan address, and newborn chicks are expected within the next two weeks, according to avid bird-watchers who monitor the nest daily and report the activity on the Internet. The nest is at 927 5th Ave. -- 12th floor, above the cornice -- and the residents are Pale Male and Lola, the red-tailed hawks whose highly publicized eviction in December sent feathers flying among urban naturalists.

The great white shark has left the building. After an eventful six months on display, a young female great white shark that set survival records in captivity while luring hordes of visitors to the Monterey Bay Aquarium was released Thursday in waters south of the facility. The shark, outfitted with an electronic data tag that will track her movements for the next month, wore out her welcome by following nature's course.
