It started with a single female. In the summer of 1987, a member of the Southern Resident killer whale population—specifically from the K-Pod—was spotted swimming near the Puget Sound with a dead Pacific salmon balanced perfectly on her head. It looked ridiculous. It looked like a hat. Honestly, if you saw a photo of it today without context, you’d probably assume it was some weird AI-generated meme or a very specific Photoshop job. But it was real. And then, it spread.
Within a few weeks, the orca wearing salmon hat phenomenon wasn't just a one-off fluke. It became a full-blown cultural craze among the local pods. By the time the "fashion season" peaked, whales from L-Pod were doing it too. Imagine these massive, apex predators—creatures capable of taking down sharks—patrolling the cold Pacific waters while essentially wearing their lunch as a fascinator. It’s one of the most bizarre documented cases of non-human "fads" in the natural world.
Researchers were baffled. Was it a game? Was it a display of status? Was it just because one influential whale did it and the others thought she looked cool? The "salmon hat" incident remains a pillar of cetacean behavioral studies because it proves something we often hate to admit: animals can be just as trendy and nonsensical as humans.
How the Salmon Hat Craze Actually Happened
We like to think of animal behavior as strictly functional. Evolution usually dictates that if an animal spends energy on something, it’s for food, mating, or survival. But the orca wearing salmon hat trend defied all that logic.
The timeline is pretty tight. After the first sighting in July 1987, the behavior rippled through the community. Biologist Ken Balcomb, who founded the Center for Whale Research, was one of the primary observers during this era. He saw these whales carrying dead, rotting salmon for hours, sometimes days. They weren't eating them. They were just... wearing them.

By August and September, sightings were everywhere. You’d have multiple whales in a pod all sporting the same "accessory." It wasn't just a quick balance act, either. These whales were surfacing, diving, and traveling long distances without letting the fish slip off. Then, as quickly as it started, the trend died. By the following summer, the salmon hats were gone. Aside from a very brief, half-hearted resurgence a few years later, the "style" never truly came back. It was a 1987 exclusive.
The Science of Cetacean Social Learning
Why do they do it? Basically, it comes down to social learning and cultural transmission. Orcas are incredibly intelligent, with brains that possess a highly developed paralimbic system. This part of the brain handles emotions and social bonding.
When an orca wearing salmon hat becomes a common sight, it’s because orcas are "cultural" animals. They have dialects. They have specific hunting techniques passed down through generations. And, apparently, they have temporary fads. Scientists like Dr. Luke Rendell and Hal Whitehead have written extensively about this. They categorize the salmon hat as a "temporary cultural variant."
Think about it like the "Ice Bucket Challenge" or wearing your hat backward. There is no biological advantage to it. In fact, it might even be a slight disadvantage—dragging a dead fish around creates extra drag and smells terrible as it decomposes. But if the "cool" whales are doing it, the younger whales are going to copy it. It’s a way to reinforce social bonds. It’s "playing" in a way that shows they are part of the group.

Why the Southern Residents Are Different
It is vital to recognize that not all orcas are the same. You have Transients (Biggs), Offshores, and Residents. The Southern Residents, who live in the waters of British Columbia and Washington State, are specialized salmon eaters. They are picky. They almost exclusively hunt Chinook salmon.
Because their survival is so tied to this one specific prey, their relationship with salmon is complex. To them, a salmon isn't just a calorie source; it’s the center of their entire universe. Does that explain the orca wearing salmon hat? Sorta. It’s possible that during a year of relative abundance, the whales had enough "leisure time" to mess around with their food. When salmon numbers are low, you don't play with your dinner; you eat it.
Other Weird Orca Fads You Should Know
The salmon hat isn't the only time orcas have acted like bored teenagers.
- The Boat Rudder "Attacks": More recently, near the Iberian Peninsula, orcas have been targeting sailboats. They aren't trying to eat the people. They are breaking the rudders. Some scientists believe this is just another fad—a high-stakes game of "break the toy" that has spread through the local population.
- Kelping: Many pods engage in "kelping," where they wrap themselves in giant kelp fronds and swim around. This seems to be a sensory experience, perhaps feeling like a massage or a spa day.
- Harassing Porpoises: Southern Residents have been seen "playing" with harbor porpoises to the point of killing them, but they never eat them. It's a dark, disturbing version of a "fad" that researchers are still trying to understand.
What This Tells Us About Animal Intelligence
Honestly, the orca wearing salmon hat story is a humbling reminder that we don't know as much as we think we do. We try to categorize every animal movement into "mating," "foraging," or "defending." But orcas have massive amounts of gray matter dedicated to social complexity.

They get bored. They play. They have "in-jokes" that we will never understand because we don't speak their language or experience their acoustic world. The salmon hat was a visual joke or a social signal that made sense to them for exactly one season.
There’s a nuance here that often gets lost in clickbait articles. People want to believe the whales were "honoring" the salmon or doing a ritual. There’s zero evidence for that. It’s much more likely that it was just fun. The salmon’s body has a certain weight and texture that probably felt interesting when balanced on the rostrum or near the blowhole. Once the novelty wore off, they moved on to the next thing.
Looking Forward: Will the Hats Return?
We haven't seen a major "salmon hat" season in decades. Part of the reason might be depressing. The Southern Resident orcas are currently endangered. Their population is struggling due to noise pollution, toxins, and a massive decline in Chinook salmon stocks.
It’s hard to have a "fashion season" when you’re starving. Most of their energy now goes into simply finding enough fish to survive the winter. The 1987 orca wearing salmon hat phenomenon might have been a luxury of a healthier ecosystem—a time when there was enough food that a whale could afford to wear a fish instead of swallowing it.
Actionable Insights for Ocean Enthusiasts
If you're fascinated by this behavior and want to help ensure orcas have the "leisure time" to be weird again, there are specific things you can do that actually matter.
- Support Salmon Recovery: The Southern Residents live and die by the Chinook. Supporting dam removal projects on the Snake River or supporting sustainable fishing practices is the most direct way to help.
- Be a Responsible Whale Watcher: If you're on the water, follow "Be Whale Wise" guidelines. Give them space. Noise from boat engines interferes with their echolocation, making it harder for them to hunt (and play).
- Report Unusual Sightings: If you are a boater or a coastal resident, use apps like WhaleReport to log sightings. Scientists rely on this "citizen science" to track new behaviors or potential new fads before they disappear.
- Watch for the "Iberian Trend": If you travel to Europe, stay updated on the rudder-breaking behavior. It is the modern equivalent of the salmon hat, albeit much more destructive to human property.
The orca wearing salmon hat story is more than just a funny bit of trivia. It’s a window into the cultural lives of one of the planet’s most sophisticated minds. It reminds us that the ocean is full of individuals with personalities, preferences, and, occasionally, a very questionable sense of style.
