Rare Orca Trio Surprises Whidbey Island Residents with Unexpected Visit

Whidbey wildlife photographer Cindi Rausch was watching from East Point when three orcas she had never seen before moved through Saratoga Passage in mid-March. Photographer Sarah Geist, who also captured images of the trio, told the News-Times she was ecstatic to see them. Neither had cause to recognize the animals: Bay Cetology reports that over 99.5% of orcas photographed in the Salish Sea are well-known individuals. These three were not.

Bay Cetology, a Pacific Northwest nonprofit that tracks local whale populations, assigned the group provisional catalog names T419, T420, and T421, designating them as the 419th, 420th, and 421st known transient orcas not descended from a known female. T419 is an adult female with a jagged cut on the inside edge of her dorsal fin; T420 is a juvenile male; T421 is a calf.

The trio traveled up Possession Sound and through Saratoga Passage as part of a multi-day journey from Vancouver Harbour in British Columbia down to Olympia, Washington. On March 11, T420 was photographed surfacing after swimming under the Des Moines Marina pier. Three days later, T419 and T420 spent the day in Admiralty Inlet alongside some of the region's well-known resident whale groups. As of March 24, the Orca Conservancy reported all three had returned to Puget Sound.

The whales' bodies told part of their story. Multiple researchers noted circular scars consistent with cookie-cutter shark bites, described as "about the size of a large chocolate-chip cookie." Gary Sutton of the Vancouver-based nonprofit Ocean Wise cited those scars as indicators of offshore origins, and Howard Garrett, board president and co-founder of the Orca Network, noted they suggest time in tropical or sub-tropical waters. Scientists believe the animals may have originated from the Gulf of Alaska, the Aleutian Islands, or the Bering Sea.

The trio was first documented near Anchorage, Alaska in March 2025 and had never been observed in Canada before surfacing in Vancouver's Burrard Inlet in early March 2026. Bay Cetology researcher Jared Towers called the Vancouver sighting a significant discovery: it marked the first time any Bigg's killer whale population other than West Coast transients had been observed in the Salish Sea in more than 50 years of documented B.C. whale research.

A California-based organization, the Oceanic Research Alliance, assigned competing names: OCX085, OCX086, and OCX087. The Orca Conservancy entered the whales into FinWave, an AI-powered database that identifies orcas from photo submissions, and the analysis supported the Alaskan Transient hypothesis. Shari Tarantino, the Orca Conservancy's executive director, noted the Alaskan transients "appear unexpectedly friendly" with orcas in the West Coast transient population. Garrett described the visitors as "certainly culturally distinct" from the West Coast transients regularly sighted from Whidbey, while acknowledging that genetic and acoustic distinctiveness remains undetermined.

The sightings arrived against a stark conservation backdrop. The endangered Southern Resident killer whale population has declined to approximately 73 to 74 animals, a 30-year low tracked by the Center for Whale Research in annual census work dating to 1976. Roughly 500 Bigg's orcas, the mammal-eating type the mystery trio appears to be, exist by comparison. The three animals' monthlong transit from British Columbia to Olympia, documented by Whidbey photographers and AI tools in near-real-time, is a reminder of how much about orca movement remains unknown even in one of the world's most closely monitored marine ecosystems.
