George Divoky is a scientist in Seattle, at least most of the year. But don’t expect to find him around here during the summertime. He’ll be on a small, flat little island in the Arctic Ocean, off the Alaska coast, called Cooper Island. Back in 1975, Divoky was doing survey work there, when he came across a colony of arctic birds called Mandt’s Black Guillemots. They’re little pigeon-sized birds with bright red legs, and they’re one of the few seabird species that depend year-round on sea ice.
