This from a comment by Dee Johnston on my post about Tilikum’s state of mind:
With regard to the Education of Seaworld: I found on a message board that someone had contacted Seaworld and asked “Is Tillikum transient or resident?” and Seaworld replied:“Thank you for contacting the SeaWorld Parks and Entertainment Family of Parks. We appreciate your questions as they are invaluable in helping us provide you with world class service.
Tillicum lives at our Orlando facility full time.
Thank you again for your interest!

That is definitely a different definition of “resident.”
In my research I also pursued this question. And the best answer I could come up with is that the orca population off eastern Iceland, where Tilikum came from, shows resident characteristics. Another key point is that the Icelandic orcas were caught either by following the herring fleets, or by dumping herring into the water ahead of a pod. So Tilikum almost certainly came from a fish-eating population, which reinforces the notion that he is more likely resident than transient.
One other very interesting question raised for me by orca biologists is whether transient killer whales that are taken into captivity–used to eating and hunting large mammals–are more likely to be involved in trainer incidents. There probably are not that many transients kept at marine parks since most of the killer whales taken into captivity were taken from the Pacific Northwest and Iceland, from resident populations. But it is an interesting idea.
Anyone have insights into this transient versus resident question?
