"In the past 13 days, we have spotted 98 northbound gray whales (including 36 calves): the highest calf numbers to date since 2006," reports Director Alisa Schulman-Janiger at ACS/LA (#6). (Calf counts at this post generally peak around April 25.) Many of the whales passed so close that observers could hear them blow, and bottlenose dolphin and sea lions leaped playfully among the whales. Wouldn't you love to be there?

At Post #7, Michael Smith's Counters have had one great day after another (see data). Yesterday,(April 26, "it was almost non-stop whales" from the opening. They added seven more calves in an altogether fantastic day," reported Director Michael H. Smith. But boat traffic on April 19 kept them on edge as they watched the cow/calf parade.

Great news also comes from Wayne Perryman's scientific study site at Pt. Piedras Blancas Lighthouse Station (Post #8). The northbound pulse of gray whale calves is now in full swing, with 19 c/c pairs spotted April 26. Mr. Perryman now has hopes of beating last year's low total of 71 calves. Find out something that has make him think, question and wonder.

Farther north, happy whalewatching cruisers at Post #15 (Vancouver, CA) reported their first mom/calf pairs, and the whales have been streaming past Kodiak Island, Alaska (#16) as they enter the home stretch of their over-5,000-mile migration.
