Nature is usually pretty predictable. Predators hunt, prey runs, and everyone tries to stay alive long enough to pass on their genes. But in the summer of 1987, something went sideways in the waters of the Pacific Northwest. Specifically, within the southern resident killer whale population of the Salish Sea. It wasn't a change in migration or a new hunting technique. It was a hat. A dead fish hat.
The orca salmon hat 1987 phenomenon is one of the most cited examples of non-adaptive social learning in non-human animals. It basically started with one female from K-Pod. She decided, for reasons known only to her, that carrying a dead Pacific salmon on her nose was the "it" look for the season.
It sounds like a joke. It wasn't. For several weeks, this bizarre behavior spread like wildfire through the community. If you were a cool orca in 1987, you weren't just eating your salmon; you were wearing it.
How a Dead Fish Became High Fashion
Whales are smart. Really smart. We know they have complex dialects and intricate social structures. But the 1987 salmon hat craze showed us they also have a sense of... style? Or maybe just a collective sense of humor.
The trend began in the Puget Sound area. A female orca from K-Pod was first spotted balancing a dead chinook salmon on her snout. She wasn't eating it. She was just swimming around with it. Within a few weeks, the behavior jumped pods. Soon, orcas in L-Pod were doing it too. Researchers from the Center for Whale Research were baffled. They watched as dozens of apex predators spent their afternoons carefully balancing fish carcasses on their heads like they were walking a runway in Paris.
Why did they do it? Honestly, nobody knows for sure.

Biologists like Ken Balcomb, who spent decades studying these specific pods, observed that the behavior served no obvious biological purpose. It didn't help them hunt. it didn't help them attract mates in a traditional sense. It was a fad. Pure and simple. Just like humans wearing neon leg warmers or mullets in that same decade, the orcas were doing something simply because they saw someone else doing it.
The Viral Spread of K-Pod Culture
Social learning is a hallmark of high intelligence. Most of the time, we see it used for survival. For example, some orcas in the Antarctic have learned to create waves to wash seals off ice floes. That makes sense. It's a tool for dinner.
The orca salmon hat 1987 trend was different. It was what scientists call a "cultural transmission of a non-utilitarian behavior." In plain English: it was a meme.
It spread because orcas are incredibly social creatures. They spend their entire lives in close-knit family groups. They watch each other. They mimic each other. When the trend reached its peak that summer, you could see multiple whales in a single group all "wearing" their fish. It wasn't just a fleeting moment, either. This lasted for a solid five or six weeks.
Then, just as quickly as it started, it stopped.

By the time the 1988 season rolled around, the salmon hats were gone. A few whales tried to bring it back briefly a couple of years later, but it never regained its former glory. The "cool kids" had moved on. The fish was out; being a regular whale was back in. It’s a fascinating look at how "culture" isn't just a human construct. It exists in the deep blue, too, complete with embarrassing phases.
What This Tells Us About Animal Intelligence
We often try to categorize animal behavior into boxes like "instinct" or "survival." The 1987 incident breaks those boxes. It suggests that orcas have enough "leisure time" and cognitive surplus to engage in activities that are purely for play or social bonding.
Some researchers have theorized that the salmon hats were a way of signaling status or simply a form of play that got out of hand. Think about how a group of teenagers might all start using a specific slang word. It doesn't help them find food or shelter, but it reinforces their connection to the group.
- Social Cohesion: Mimicry strengthens the bonds between pod members.
- Play Behavior: Young orcas are notoriously playful, and many "fads" start with the juveniles.
- Cognitive Mapping: Learning to balance a heavy, slippery fish while swimming at high speeds actually requires significant motor control.
There’s also the possibility that it was a way to "scent" themselves or play with their food in a way that provided sensory feedback. But the most widely accepted theory remains that it was a social fad. It proves that orcas have a "cultural life" that is independent of their biological needs. They have trends. They have "in" groups. They have moments of collective weirdness.
The Legacy of the Salmon Hat
While the 1987 event is the most famous, it’s not the only time we’ve seen orcas do strange things. In recent years, we’ve seen orcas in the Strait of Gibraltar "attacking" sailboats. While some call it an uprising, many researchers suspect it might be another fad—a game that spread from one whale to the rest of the group.

The orca salmon hat 1987 serves as a reminder that we are sharing the planet with minds that are, in some ways, very similar to our own. They get bored. They experiment. They follow the crowd.
When we look at the Southern Resident orcas today, they are struggling. Chinook salmon populations—the very fish they used for hats—are dwindling. Lack of food, boat noise, and pollution are pushing these pods to the brink. Looking back at 1987 feels like looking at a "golden age" of whale culture, where the biggest concern was whether your fish hat was sitting straight.
Actionable Insights for Whale Enthusiasts
If you're fascinated by orca behavior and want to help ensure they stay around long enough to start their next weird trend, there are a few things you can actually do:
- Support Salmon Restoration: The Southern Residents almost exclusively eat Chinook salmon. Supporting organizations like the Long Live the Kings or the Save Our Wild Salmon coalition helps restore the habitat these whales need to survive.
- Practice Responsible Whale Watching: If you're on the water, follow the "Be Whale Wise" guidelines. Stay at least 300-400 yards away. Noise from boat engines interferes with their ability to hunt and communicate.
- Reduce Chemical Runoff: Orcas are apex predators, meaning they accumulate toxins (like PCBs) from every fish they eat. Using eco-friendly household products helps keep these chemicals out of the Puget Sound.
- Stay Informed via Real Research: Follow the Center for Whale Research. They are the ones who originally documented the 1987 fad and continue to track the health of J, K, and L pods.
The story of the salmon hat is more than just a quirky trivia fact. It’s a window into the complex, social, and sometimes nonsensical inner lives of one of Earth's most intelligent species. It reminds us that nature isn't just a series of cold, calculated survival moves. Sometimes, it's just a whale with a fish on its head, enjoying the summer.
