Climate Change Compounds Threats to Birds

Each spring the red knot, a shorebird with a rust-colored belly, transects the globe, flying from the southern tip of South America to the northern reaches of the Arctic. Midway through this flight, the birds lay over at the Delaware Bay, where they refuel by gorging on tens of thousands of horseshoe crab eggs.

In the 1990s, this age-old migration ran into trouble when red knot populations began crashing. Evidence pointed largely to shellfish overharvesting, but recent observations by birders and researchers have revealed an additional threat from climate change: Warmer temperatures are prompting the horseshoe crabs to lay their eggs earlier in the year, meaning less food for the migratory birds when they arrive at the bay.

These findings and other research about the impact of climate change on birds are the focus of the 2010 State of the Birds report, issued by scientists from the Cornell Lab of Ornithology, The Nature Conservancy, federal agencies and other organizations. The group’s 2009 report found that roughly one-third of bird species in the United States are endangered or are in serious decline.

A few weeks ago, Fort Collins hosted the most critical moment in the history of the American cattle industry, at least according to one rancher advocacy organization.

I covered the proceedings for MatterDaily.org in an essay-ish news story, published September 10, 2010, “Down on the Farm.”
