News: Cows and Calves are Coming! | ||||||||||||||||||||
North to Alaska! The first report from Kodiak (Post #16) was 15-20 gray whales spotted from the cliffs of Narrow Cape on Monday, April 2nd. Woo hoo! Just in time for Whale Fest Kodiak, the annual celebration of the whales' return.
Last time Kati from Post #15 in Vancouver, Canada, predicted moms and babies off Tofino about three weeks after the first sighting (March 20/21) at Post #6 (ACS/LA). "And sure enough," reports Kati, "on Saturday of the Easter Holiday weekend we encountered our first Gray Whale mother & calf pair off Tofino!" Counting the Whales Passing California What's the news at Post #6 on the migration route? ACS/LA Gray Whale Census and Behavior Project Director Alisa Schulman-Janiger reports: "Our cow/calf migration phase has begun. We have spotted 8 of our 11 northbound calves since March 26." They saw a gray whale breach seven time in a row! But boat traffic mixed with whale traffic here, too: A calf on April 9 was traveling a distance from the mom, even swimming in front of her. "Then a small motor boat came fairly close to them; the next time they surfaced, the calf was right next to the mom, riding back toward her dorsal ridge in classic cow/calf formation." They saw zero grays but lots of orcas on April 7; do you think there's a connection? Read the field notes to see why March 29 was so exciting at Post #6! Official Calf Count: Scientific Research Site Next?
Alisa Schulman-Janiger predicts: "Calf counts [in California] should continue to increase in number over the next few weeks, and will probably peak near the end of April." Read Field Notes |

Gray whale babies migrate more than 5,000 miles when just a few months old. No wonder observers all along the route are eager to see them pass by with their mothers. But how easy is it to see a baby whale on migration? Join some observers that saw cow-and-calf pairs along the California coast in this slideshow: | ||||||||||||||||||||

Tracking the Migration: Using Daily Data |

"Each day we talk about now being in the calf phase of what is actually two separate migrations: the general population and the cow/calf pairs," comments Michael Smith at Observation Post #7. What migration story do the data tell this week? What was the largest day for whale sightings at both point-count posts? This week, summarize what the data show about the migration phase. What do you think will happen next?
