Killer Whales Offer Fish to Humans Like Cats Bring Mice todayheadline

Wild orcas around the world are deliberately sharing their freshly caught prey with humans, offering everything from fish and seals to stingrays in what researchers describe as genuine attempts at interspecies communication.

A comprehensive study documenting 34 such encounters across two decades suggests these intelligent marine mammals may be trying to build relationships with us—much like a house cat dropping a dead bird at your feet.

The research, published in the Journal of Comparative Psychology, analyzed incidents from four oceans where killer whales approached people on boats, in the water, or even on shore to offer food. In nearly every case, the whales waited patiently to see what humans would do with their gifts before retrieving them or swimming away.

Global Pattern Suggests Intentional Behavior

“Orcas often share food with each other—it’s a prosocial activity and a way that they build relationships with each other,” explained lead author Jared Towers of Bay Cetology in British Columbia. “That they also share with humans may show their interest in relating to us as well.”

The documented encounters span impressive geographic and temporal ranges:

• 34 incidents recorded between 2004 and 2024
• Six different orca populations from California to Norway to New Zealand
• 18 different species offered, including fish, mammals, birds, and invertebrates
• 97% of cases where whales waited for human responses before acting

The offerings weren’t random scraps. Whales presented whole prey in half the cases, suggesting they were sharing valuable meals rather than disposing of leftovers. When humans ignored the gifts—which happened 88% of the time—the orcas typically retrieved their food and either left or shared it with other whales nearby.

Unprecedented Insights Into Wild Animal Behavior

While domesticated animals like cats and dogs sometimes offer food to their human companions, this study marks some of the first detailed documentation of similar behavior in completely wild animals. The researchers established strict criteria for inclusion, ensuring the whales approached humans voluntarily and dropped items directly in front of them.

The most intriguing aspect may be the whales’ apparent expectation of reciprocity. In seven cases, orcas made multiple attempts to offer food after initial rejections. When humans occasionally accepted and returned items, some whales immediately offered them back again, suggesting a form of back-and-forth communication.

“Offering items to humans could simultaneously include opportunities for killer whales to practice learned cultural behavior, explore or play and in so doing learn about, manipulate or develop relationships with us,” the researchers wrote.

Not Just Playful Youngsters

Contrary to expectations, the behavior wasn’t limited to curious juveniles. All age classes participated, from calves to fully grown adults, with roughly equal representation by sex and age that mirrors healthy orca populations. This broad participation suggests food sharing with humans represents learned cultural behavior rather than mere youthful experimentation.

The pattern also revealed population-level differences. Only orcas from groups that hunt marine mammals and large prey near the surface offered food to humans. Populations that primarily eat fish using echolocation at depth showed no such behavior, despite extensive human contact in some areas.

This distinction hints at underlying cognitive differences. The sharing populations live in visually rich environments where they cooperatively hunt large, warm-blooded prey—circumstances that may favor exploratory intelligence and social flexibility.

Evolutionary Parallels With Human Behavior

The researchers draw fascinating parallels between orca and human societies. Both species evolved as apex predators—orcas in marine environments, humans on land—with minimal competitive overlap. This unique relationship may reduce the costs of interaction while potentially offering benefits through mutual curiosity and learning.

The study also noted that only certain orca lineages engage in human provisioning, with some individuals documented making multiple offerings. This suggests the behavior may be culturally transmitted within family groups, similar to other orca traditions like hunting techniques and communication patterns.

However, the researchers caution against romanticizing these encounters. Captive orcas have been known to use prey as bait to attract and sometimes harm other animals, and the species’ intelligence enables complex manipulative behaviors.

As human activities increasingly overlap with orca habitats, such encounters may become more common. While the whales’ apparent interest in communication represents remarkable interspecies behavior, the researchers strongly recommend against encouraging these interactions due to unpredictable risks for both species.
