[CINC] Gray whale migration changes - Perryman, Harvey; by Upton, NYT

[Marty Flam]

"...more calves born before they get all the way down to Mexico..."

"...begun feeding off the northern Californian coastline, pursuing different prey than is found in polar waters..."

"...the population appears to be relearning direct migration routes that were forgotten when many of the giant mammals were slaughtered by whalers.
The whales have learned to go west around the Channel Islands off Southern California, instead of hugging the coast..."
