How many SRKW are left?

As of December 31, 2020, the SRKW population totals 74 whales: J Pod=24, K Pod=17, L Pod=33. The size of all three Southern Resident pods was reduced in number from 1965-75 as a result of whale captures for marine park exhibition.

Where do southern resident orcas go in the winter?

Pacific Ocean
The Southern Resident killer whales spend much of the winter along the coast in the Pacific Ocean. This is because their main food source is salmon. Since the salmon numbers decrease in the Salish Sea during the winter, resident killer whales disperse and hunt for salmon in the open North Pacific.

What is the difference between resident and transient killer whales?

In the Pacific Northwest one group of killer whales feeds exclusively on salmon. These are referred to as “residents” because they remain in inland or nearby coastal waters. A second group, known as “transients,” feeds only on marine mammals. More information on offshore orcas can be found at Orca Network.

Why are the southern resident killer whales dying?

Current threats: There are three main reasons for the decline in Southern Resident Orcas: lack of food, noise pollution, and chemical pollution. Today, two-thirds of orca pregnancies fail due to nutritional stress. Their population decline is primarily due to a decline in Chinook salmon abundance.

Do transient orcas eat humans?

Transient orcas, which have a broader diet, have shown similar selective behavior, in one case killing a gray whale but eating only its tongue. There have reportedly been incidents where an orca attempted to hunt a human, but broke off the hunt immediately upon realizing it wasn’t a sea lion.

Why do orcas only eat chinook salmon?

Chinook salmon is the largest and fattiest of all the Pacific salmon and therefore supplies the most calories for the effort expended in catching it. The Southern Residents are extremely active with high energy needs, and this is most likely why they favor Chinook.

What happens to a dead orca?

Burial at sea When a whale dies at sea, its gas-filled and blubbery body usually stays afloat for a while. The floating time varies among individuals and species. Still, species with more blubber generally float longer.

Where do orcas live in the Puget Sound?

Read on to find out how you can help, and come visit us at the Puget Sound Orcas: Family Activity Center at the Seattle Aquarium to learn more.
