The last post of 2011

On December 23rd I got to see something that I have been wanting to see for years. It was at the top of my "to see" list. I saw an attack on gray whales by a pod of orcas. There were 4 orcas (and one was a calf) and 2 adult gray whales. The numbers were certainly in favor of the grays and they did win the battle.

I was working at the North end of our study range at Sea Lion Cove and waiting for a sleeping otter to show me her flipper tags. She was dead asleep and I figured I would be there a while so I pulled my camera out to take some hummingbird photos. (previous posts have photos of hummingbirds from this very spot!) While looking offshore I was thinking to myself, this feels like and orca kind of day. The ocean was flat and you could see for miles. About 5 minutes after I thought about the orcas I saw some splashing close to shore. I looked down and saw 2 gray whales on their backs. I thought maybe they were mating. Although most grey whale mating behavior happens far south of us in Baja Mexico, I have seen mating along their travel route a few times.
I started taking some photos of them and then realized there was a dolphin dorsal fin right by the gray's head. I looked a little closer and saw the white saddle patch (a telling characteristic of orcas). I kept taking photos, but was so excited that I was jumping up and down and actually for once, hoping that tourists would stop and I could tell them what was going on. The encounter only lasted about 7 minutes and the orca pod started swimming south and offshore. The grays were underwater for a long time and appeared to 'wrangle up' some more whales that were on their way south. Soon there were 5 grays all swimming together within 200 meters of shore- often through the kelp. Just south of their current location is a deep canyon and this is where it would be easiest for orcas to attack. Often when the mothers and calves are traveling north there are attacks in the deep canyons off Monterey and Carmel.

After the orcas swam offshore, I believe they got a sea lion (a little easier breakfast option that a 40 foot long gray whale) and I took some photos but at this point they were about a mile offshore so the quality is not as good.

After the attack the grays started back south but were swimming very close to one another and close to shore.
