FIGURE 1: Movements of two groups of transient killer whales (labeled CA20 and CA122) tagged in Monterey Bay, CA in April 2010. Pod CA122 (shown in red) traveled the coastline between the Columbia River in the north and the Channel Islands in the south - a linear distance of more than 1300 km, and this range was covered twice in one month. Pod CA20 (shown in blue) covered a shorter range more frequently.
