Unformatted text preview: Endangered Cranes Killed in Fla. Storms February 3, 2007 MILWAUKEE (AP) -- All 18 endangered young whooping cranes that were led south from Wisconsin last fall as part of a project to create a second migratory flock of the birds were killed in storms in Florida, a spokesman said. The cranes were being kept in an enclosure at the Chassahowitzka National Wildlife Refuge near Crystal River, Fla., when violent storms moved in Thursday night, said Joe Duff, co-founder of Operation Migration, the organization coordinating the project. ''The birds were checked in late afternoon the day before, and they were fine,'' he said Friday. The area of the enclosure was unreachable by workers at night, and all the birds were found dead, Duff said. He speculated that a strong storm surge drew the tide in and overwhelmed the birds. The official cause of the deaths was not immediately known, but he said it may have been drowning. For the past six years, whooping cranes hatched in captivity have been raised at the Necedah National Wildlife Refuge in central Wisconsin by workers who wear crane-like costumes to keep the birds wary of humans. Ultralight aircraft are used to teach new groups of young cranes the migration route to Florida. From then on, the birds migrate north in the spring and south in the fall on their own. Duff described the loss as an ''unavoidable disaster'' for the whooping cranes project that ironically followed a milestone. For the first time in six years, an entire group of young birds reared at the Necedah refuge had made it to the Florida refuge without the loss of a single crane. The flock grew to 81 birds with the latest arrivals, but the loss of the young cranes drops the total back to 63. Common Themes in Mass Extinctions ? Polar Bears' Plight Raised In Drill Bids For Oil, Gas By Steven Mufson, Washington Post Staff Writer Thursday, February 7, 2008; Page D01 The Interior Department yesterday announced $2.6 billion in winning bids from companies seeking to drill for oil and gas in Alaska's Chukchi Sea despite protests from environmental groups and members of Congress that oil and gas exploration would endanger polar bears. Companies made 667 bids for 448 tracts in the 29 million-acre area north of Point Barrow. The winning bids included a record- breaking $105.3 million offer by Shell Oil for one three-by- three-mile leasehold, almost twice as much as the previous high bid for a single offshore U.S. tract. Environmental groups said, however, that they doubted the area, home to about one-tenth of the world's polar bears, could be explored without high risks of a spill and damage to the habitat of the bears and other wildlife, such as walruses and bowhead whales....
