After 37 years, orcas in the Pacific Northwest are once again donning dead salmon as headwear. The orcas were last seen doing this in 1987. This behavior has researchers scrambling to understand them, wondering if this is playful mimicry, a cultural revival, or something entirely new.
A Glimpse Into Orca Culture
This behavior isn’t just random—it highlights the social lives of orcas and that they are anything but known to us. These marine mammals share and learn behaviors in much the same way humans do. The return of the “salmon hat” suggests deep cultural roots within their pods.
Why Salmon Hats
Researchers theorize that an abundance of chum salmon in the region might explain this trend. When food is plentiful, playful or experimental behaviors often emerge. They may also be storing the salmon for later.
A Display of Intelligence
Orcas are known for their intelligence and playful nature. Naomi Rose from the Animal Welfare Institute believes the salmon hats may serve no purpose other than amusement—a perfect showing of the orcas’ creativity and social behavior.
A Historical Fad
First observed in the 1980s, the salmon hat trend seemed to start with a few “trendsetter” orcas before spreading to their pod mates. Much like human fads, the behavior disappeared after a few years, only to come back decades later. Others suggest that these orcas could even have been the same ones that started the fad in the 1980s.
How It’s Being Studied Today
Researchers are trying their best to unravel the mystery. Modern technology could hold the answer. Drones allow scientists to monitor orca behavior more closely than ever, capturing intricate details that weren’t possible during the 1980s.
Beyond Salmon Hats: Other Orca Quirks
Orcas display a wide range of behaviors across their pods, from rolling in kelp to playful interactions with boats. These activities, while seemingly frivolous, can help scientists to understand more about how the orcas go about their day-to-day lives.
Social Learning at Play
Orcas are capable of teaching their offspring behaviors. Orca peers in groups are also capable of learning things from each other. The salmon hat may have been revived by older orcas sharing it with younger generations.
Fun or Functional?
Some scientists speculate the hats could serve a practical purpose, such as storing or marking surplus food. However, most agree that the behavior appears purely recreational—a rare and fascinating trait in the animal kingdom.
Pods vs. Trends
Interestingly, not all orca populations exhibit this behavior. The salmon hats appear limited to specific pods, hinting at unique behaviors within the orca community, much like humans. Time will tell if this trend spreads to more pods.
Abundance Fuels Creativity
The South Puget Sound is currently experiencing a boom in chum salmon populations. With an abundance of food, the orcas could be experimenting or expressing themselves with the revival of the salmon hat.
What Makes Orcas So Unique?
Orcas are some of the only animals that display behaviors that resemble human trends or fads. They seem to almost have a culture that shows off their intelligence. Every move must be made to protect the orcas and their habitats if we’re going to study them long-term.
What’s Next for the Salmon Hat?
Whether the salmon hat becomes a permanent fixture or fades like a fleeting trend, it highlights the playful, social nature of orcas. Researchers will continue to monitor their behavior, and they will be ready to see how their behavior changes in the following years.
