Whale Watching: News From Observation Posts >> 

Hopeful whale watchers are flocking to the Mexican lagoons and the Pacific Coast from far and wide to see the whales. We've heard from our official observers at points marked by yellow arrows on this globe. Observers at the lagoons (#2 and #3) are seeing fewer whales than last year. Is that also true at the Los Angeles observation post (#5)? See the answer at a glance on this line graph.

The big question is: Where are the gray whales? Have more whales stayed in and around the Bering Sea, taking advantage of the smaller-than-usual ice pack to spend more time feeding? Is the migration running late? Gray whales are still swimming south, but changes are afoot. What stories came from the observation posts? Here's the news! >>
