Story. Elusive wolves caught on camera. (bad link fixed) By Rebecca Morelle. Science reporter, BBC News.
This an interesting story about Arctic wolves on Ellesmere Island.
One sentence bothers me — “The team was also amazed by the wolves’ boldness.” When wolves don’t run but come and examine something new, they are often called “bold.” This is a completely anthropocentric view. We don’t if wolves they haven’t seen humans (or who have, but haven’t been harmed) are fighting an urge to flee or not.
