Raccoons may solve puzzles out of curiosity rather than simply in search of food, according to new research examining their behaviour. The animals are well known for their ability to access rubbish bins and compost containers, often overcoming relatively secure latches. Scientists suggest this adaptability may be linked not only to hunger but also to an intrinsic motivation to explore.

Researchers from the University of British Columbia carried out experiments using a specially designed puzzle box with nine possible entry points of varying difficulty. The device contained a single marshmallow reward and included mechanisms such as latches, sliding doors and knobs. During 20-minute trials, raccoons frequently continued opening additional mechanisms even after retrieving the food.
The behaviour indicates that the animals were seeking information rather than simply a reward. Observations showed that raccoons often explored multiple solutions and varied the order in which they attempted them. When puzzles became more difficult, the animals tended to rely on a familiar method while still occasionally exploring other options.

Researchers say this flexible approach may help explain why raccoons adapt so successfully to urban environments. Their problem-solving ability, combined with highly sensitive forepaws used to manipulate objects, allows them to access a variety of human-made food sources. Scientists believe understanding these cognitive traits could also help inform strategies for managing wildlife that interact with urban areas.
