Last Field Excursion

Calving Glacier

Our last field trip of the year to collect oceanographic samples proved to be glorious with plenty of sunshine and few animals willing to show us their stuff. We saw seals, sea otters, orcas, and a myriad of birds. And we pulled up a couple of jellies on our equipment unintentionally - they made a mess. Luckily, one of our interns & one of our volunteers were around to tag along and see what the place they've been staring at through the glacier cam all summer looks like up and personal.

Guided Mis-Information

I was hiking at a local national park the other day. I had to hike past some groups of people bundled around the entrance trail to get to more reclusive paths. As I was passing a group I heard "There's two types of killer whales: meat eaters and vegetarians".

Wha? What?? Did I hear that right? I did. Not only that but the information was coming from a park interpretive ranger guiding the group. A park ranger who lives in a town where significant killer whale research goes on. Where he has access and has talked to biologists who study killer whales. Ack!

For those of you who don't know: There are two types of killer whales. In that the ranger was correct. Now I recently finished completing a lot of work on this orca ID Catalogue for Eastern Kamchatka, Russia. I'm not a main author but I am acknowledged and let's face it, I put in a lot of work on it. So I know a little bit about the subject. I know 500 plus Russian killer whales by name.

The two types of killer whales are the Residents & the Transients. These labels are totally mis-leading and are based on previous assumptions about orcas but somehow they've stuck. Resident Orcas are fish eating orcas and they tend to not to travel very far. Transient Orcas are mammal eaters and they have to travel farther for food. But both groups tend to be loyal to a certain territory. The interesting thing as that these two groups are distinct genetically, where ever you find orcas. That means that while the orcas here at the north pole are genetically distinct from the orcas at the south pole the fish eaters and the mammal eaters in both places are still distinct from each other. So this is not necessarily a learned behavior but an inherited one. (Can you hear it now though? Orca prejudices - daddy will never speak to you again little fish eater if you marry that mammal eater!).

I can only guess that the ranger has been exposed to the saying "I'm a vegetarian but I eat fish" too often. But come on, who is he fooling? These are predators? Have you ever taken a look at those teeth? There should be a park sign that says "Please don't feed the tourists mis-information".
