Moms and Babies Remain
Single whales are leaving the nursery lagoons, but moms and babies remain. See Posts 2 and 3 for the latest counts.

Whales Passing California
"An incredible northbound whale parade!" reports scientist Alisa Schulman-Janiger at Post 6. "March 18 and 19 were our largest northbound count dates this season." Moms and babies should be coming soon. In 6 of 10 years they have arrived at Post #6 by this time.

Several days of thick fog kept many whales out of sight at Post 7 last week, but March 10 brought 25 sightings. "We usually have lots of whales going by as we hit the first days of spring," says Director Michael Smith.

Leaders in the North
"The Gray Whales continue to move north past our shores," reports Kati from Post 15 in British Columbia. "There is real 'migration energy' as they power on, rarely veering from their northward course."

A few grays are hanging out to forage in Saratoga Passage, just south at Post 13 near Seattle. The same whales do this every spring, delighting locals who wait for them.

Looking Ahead
We've seen the turnaround period; now watch for:

  • First cow/calf pair
  • Peak migration of northbound non-cow/calf pairs
  • First sightings from Alaska
