"These types of killer whales(transcients)....."

I'm curious, do we (the Orca research people) think the transcients hunt mammals because they're predisposed to do so (incapable or less adept at the methods used to hunt salmon), or because they just LIKE to?

On the flip side, I know that the local Orca researchers are wishing strongly that the resident whales (salmon hunters, unfortunately) would develop a liking for sea lion meat. It would solve everyone's problems, at least for a while.

I don't know what we'd do with an overabundance of anadromous fish around here.
