In a new study led by University of British Columbia Ph.D. student Hannah Griebling, raccoons (Procyon lotor)<\/a> continued manipulating complex puzzle boxes long after retrieving the only marshmallow reward, suggesting the animals seek information for its own sake \u2014 a behavior that may underpin their urban success.<\/strong><\/p>\n

In the study, Griebling and her colleagues used a custom multiaccess puzzle box with mechanisms such as latches, sliding doors or knobs. The box had nine entry points, grouped as easy, medium and hard.<\/p>\n

In each 20-minute trial the puzzle box contained a single marshmallow, yet raccoons often continued opening new mechanisms after eating it, a clear sign of information-seeking.<\/p>\n

\u201cWe weren\u2019t expecting them to open all three solutions in a single trial,\u201d Griebling said.<\/p>\n

\u201cThey kept problem solving even when there was no marshmallow at the end.\u201d<\/p>\n

When solutions were easy, raccoons explored broadly, trying multiple openings and varying their order.<\/p>\n

As task difficulty increased, they favored a dependable solution \u2014 but still explored multiple solutions even at the hardest level, showing flexible problem-solving<\/a>.<\/p>\n

\u201cThe pattern reflects a classic tradeoff between curiosity and effort or potential risk,\u201d Griebling explained.<\/p>\n

Raccoons adjusted strategy based on perceived cost and risk, mirroring decision-making frameworks in other animals and humans.<\/p>\n

\u201cIt\u2019s a pattern familiar to anyone ordering at a restaurant,\u201d Griebling said.<\/p>\n

\u201cDo you order your favorite dish or try something new? If the risk is high \u2014 an expensive meal you might not like \u2014 you choose the safe option.<\/p>\n

\u201cRaccoons explore when the cost is low and quickly decide to play it safe when the stakes are higher.\u201d<\/p>\n

The findings help explain why raccoons thrive in urban centers. Their success could be attributed to the cognitive and physical traits that suit urban life.<\/p>\n

Their forepaws, rich with sensory nerves for foraging in streams, are well suited to manipulating latches and handles \u2014 often the same kinds used by humans.<\/p>\n

Solving problems for information, not just food, may give them an advantage in complex environments, helping them access garbage bins or other food sources.<\/p>\n

\u201cUnderstanding the cognitive traits that help raccoons thrive can guide management of species that struggle, and inform strategies for other species, like bears, that use problem-solving to access human-made resources,\u201d Griebling said.<\/p>\n

Although the experiment involved captive animals at a research facility in Colorado, previous research suggests wild raccoons show similar problem-solving abilities, though researchers caution the behaviors may not be identical.<\/p>\n

\u201cRaccoon intelligence has long featured in folklore, yet scientific research on their cognition remains limited,\u201d said Dr. Sarah Benson-Amram, also from the University of British Columbia.<\/p>\n

\u201cStudies like this provide empirical evidence to support that reputation.\u201d<\/p>\n

The team\u2019s results<\/a> were published February 27, 2026 in the journal Animal Behaviour.<\/p>\n
