Researchers are puzzling over a widespread vitamin B shortage that appears to be killing wildlife.

During spring and summer, busy colonies of a duck called the common eider (Somateria mollissima) and other wild birds are usually seen breeding on the rocky coasts around the Baltic Sea. Thousands of eager new parents vie for the best spots to build nests and catch food for their demanding young broods.

But Lennart Balk, an environmental biochemist at Stockholm University, witnessed a dramatically different scene when he visited Swedish coastal colonies during a 5-year period starting in 2004. Many birds couldn’t fly. Others were completely paralyzed. Birds also weren’t eating and had difficulty breathing. Thousands of birds were suffering and dying from this paralytic disease, says Balk. “We went into the bird colonies, and we were shocked. You could see something was really wrong. It was a scary situation for this time of year,” he says.
