WEB DESK: Ever wondered if birds have ‘mental time travel’ powers like humans? New research suggests they might.
Study on Episodic Memory in Birds
Episodic memory is the ability to recall specific past events with incidental details. Humans might share this ability with Eurasian jays, according to a study led by James Davies from the University of Cambridge’s Comparative Cognition Lab.
Findings from the Study
Published on May 15 in the journal PLOS One, the study distinguishes episodic memory from semantic memory, which deals with factual information without personal context.
Challenges in Proving Episodic Memory
Proving episodic memory in nonhuman animals is challenging due to their inability to express thoughts. Researchers have long explored this topic, especially with corvids known for their intelligence. A previous study by Dr. Nicola Clayton revealed that scrub jays could remember the types of food they had hidden and when.

Experiment with Eurasian Jays
In the recent study, Davies and colleagues devised an experiment involving Eurasian jays. The birds were trained to find food under cups based on their positions. Later, they relied on visual cues like stickers and strings to locate the hidden treats after a 10-minute break. Remarkably, the jays successfully recalled these incidental details, suggesting a form of episodic memory.
Implications for Human Memory Research
Dr. Jonathon Crystal from the University of Indiana Bloomington praised the study’s findings, noting their significance in understanding human memory, especially Alzheimer’s disease. Insights into animal memory could aid in developing treatments for Alzheimer’s, where preserving episodic memory is crucial.
New Pathways in Memory Research
This research opens new pathways for exploring memory in animals and underscores its relevance to human memory research. It offers promising prospects for unlocking the mysteries of the avian mind.
