Antibiotic resistant bacteria found in Southern Residents (Nov 2008). Could be true for more killer whale populations and cetaceans in general.
Vancouver Aquarium’s Wild Killer Whale Adoption Programme – good natural history
Center for Whale Research’s amazing photos of an attack of transient killer whales on a harbour seal and a Dall's porpoise.
National Geographic movie (53 minutes) on killer whales - residents and transients. Addresses the threats of reduced food supply and bioaccumulation. Realize that this may be a different transient killer whale population than that found in BC.

Voices of the Sea very cool website where you can hear the sounds of cetaceans, see the spectrogram of their sounds, see video clips and learn cool facts from experts! If you click on the orca and and "sound of the orca", Dr. John Ford will tell you about residents and transients from our area (Northern Vancouver Island).
