When 12-year-old Figaro the cockatoo first saw the screen flash, he didn’t know it would mark the end of a reward—but he learned fast. At the Messerli Research Institute in Vienna, a group of Goffin’s cockatoos, including Figaro, demonstrated an astonishing cognitive leap: they learned that a once-reliable touchscreen button had stopped working after a flashing signal, and crucially, they applied that knowledge to entirely new situations. This ability to recognize when a system no longer functions—and to generalize that understanding—touches on a foundational piece of what scientists call the “minimal concept of death”: the awareness that expected behaviors or functions have permanently ceased.
For humans, death is layered with emotion, ritual, and language. But at its most basic, recognizing death may simply mean understanding that something that once responded, moved, or rewarded no longer does—and won’t again. That’s the idea behind the minimal concept of death, a framework developed within comparative thanatology. The new study, published in Scientific Reports, tests whether animals can grasp this core idea through a controlled, non-emotional task. Led by philosopher Dr. Susana Monsó and cognitive biologists Dr. Antonio J. Osuna-Mascaró and Dr. Alice Auersperg, the research zeroes in on one key component: the recognition of persistent nonfunction.
The cockatoos first learned that touching a round button on a touchscreen delivered a food reward. Then came the twist: when the button appeared on certain backgrounds, a sudden flash signaled the end of rewards in that context. The same button still worked elsewhere, but not after the flash. Over time, the birds learned to skip the now-useless backgrounds—without abandoning the button entirely. Some, like Figaro, adapted quickly, while others took more trials. Crucially, when introduced to new backgrounds that flashed, the cockatoos anticipated failure, avoiding the button even in unfamiliar settings. This showed they weren’t just memorizing patterns—they were applying a rule: flash equals nonfunction.
Individual differences were clear. Some birds vocalized or raised their crests at the flash, suggesting emotional or attentional engagement. But all demonstrated a flexible understanding of context-dependent failure. This kind of cognitive flexibility is rare in the animal kingdom and has typically been associated with primates. That cockatoos can learn and generalize such abstract rules challenges assumptions about avian intelligence.
The implications stretch beyond touchscreens. If birds can learn that a function is permanently lost in one context and expect the same in others, it suggests they possess a foundational awareness that could underpin more complex responses to death in the wild. As Dr. Monsó puts it, understanding death may not require language or ritual—just the ability to notice when something that should work, no longer does. And in Vienna, a handful of cockatoos have shown they’re already ahead of the curve.
