Scientists may have found a new population of orcas off Southern Oregon coast

Think Out Loud

Scientists at the University of British Columbia may have identified a new population of orcas, also known as killer whales, feeding in the deep waters between Astoria and Southern California, according to a recently published study. The researchers reviewed photos, videos and descriptions made by fishermen, NOAA scientists and a whale-watching tour operator during multiple encounters with the marine mammals over a span of nearly 25 years. Their distinctive appearance and feeding behaviors - including a penchant for hunting sperm whales – are some of the ways they’re unlike other killer whales that forage off the West Coast of North America. Joining us to share more details about this mysterious pod of orcas is Andrew Trites, director of the Marine Mammal Research Unit and professor at the Institute for the Oceans and Fisheries at the University of British Columbia, and a co-author of the study.
