Penguins have been spotted periodically in the wild in the Northern Hemisphere during the last 50 years. Two biologists now conclude they probably got so far from home aboard fishing boats, not by swimming.
In the wake of the U.S. government's watershed decision to propose listing the polar bear as "Threatened" under the Endangered Species Act, the Wildlife Conservation Society (WCS) is launching a bold initiative to save the Earth's largest terrestrial predator, not by following the bears themselves, but the receding sea ice habitat that may drastically shrink as a result of global warming.
Mule deer are giving new meaning to watching out for other mothers' kids. An intriguing study of mule deer and whitetail deer conducted by the University of Alberta and the University of Lethbridge showed that both species responded to the recorded distress calls of fawns, but unlike whitetail deer, the mule deer mothers responded to both whitetail and mule deer calls, even when their own fawn stood next to them.
