Millions of birds migrate through California this time of year, but the waterways and wetlands they rely on for food and rest are largely dry due to the ongoing drought. So farmers are keeping their fields flooded to make temporary wetlands, providing a place for migrating birds to rest and eat.
Rice farmer Douglas Thomas is one of these farmers. On a recent morning some 3,000 snow geese float in his rice fields in California's Central Valley. He's watching a young bald eagle awkwardly dive at the flock.
"As soon as they start getting here, this is what I sit and do," he says. "I keep my binoculars in my truck."... Read more.
Plants and animals have a long history of acclimatizing to city living - think of raccoons and their expert pillaging of compost bins. But now biologists are beginning to see signs that something more fundamental is happening. They say wild things may be changing at a genetic level to survive cities and their polluting, habitat-fragmenting ways.
Fish in New York's chemically-laden Hudson River have evolved a genetic variation that gives them resistance to PCBs, for example. Birds nesting under highway overpasses in Nebraska have developed shorter, more agile wings, allowing them to quickly swerve from oncoming traffic... Read more.
With thick fur and snowshoe-like feet, wolverines are well-adapted to live in snow caves and run straight up mountains. Their high elevation lifestyles have helped them stay out of harm’s way in recent decades, and stage a slow comeback from the rampant carnivore persecution of the early 1900s. Though elusive and tenacious, they won’t be insulated from human impacts forever. They face a precarious future as climate change eats away at the snowpack they need.
That’s why the U.S. Fish and Wildlife Service is proposing to add them to the endangered species list, even as a handful of wide-ranging wolverines are venturing into states where they haven’t been seen for generations. The agency was slated to make a listing decision earlier this month as part of a legal settlement with environmental groups. But reputable wolverine biologists have criticized the scientific underpinnings of the agency’s proposed listing decision, especially the parts related to snowpack. Now, the FWS is delaying the decision for another six months so they can reconvene with scientists about wolverine habitat and climate impacts to it... Read more.
