Gibraltar's Barbary macaques, the island's iconic residents, are reportedly supplementing their diets with soil, a behaviour scientists tentatively link to a detox from human-provided junk food. A recent informal observation, details of which are scant, suggests these primates have been seen ingesting the earth, particularly around areas frequented by tourists.
The macaques, accustomed to scavenging discarded human food, may be turning to geophagy—the practice of eating earth—as a way to absorb toxins or excess acidity from a diet high in processed snacks. This isn't the first time animal behaviour has been studied in relation to human influence on Gibraltar.
Historical Context and Natural Habitat
Gibraltar, a British Overseas Territory, is renowned for its dramatic geological formations and unique wildlife. The Upper Rock Nature Reserve is the primary habitat for the Barbary macaque population, a species also found in the Atlas Mountains of North Africa. Historically, these primates have coexisted with humans, though their reliance on readily available human food sources has become a point of concern for conservationists and observers alike. The 'Welcome To Gibraltar' portal lists various attractions and points of interest, including the Upper Rock Nature Reserve and mentions Gibraltar Monkeys as a key feature of the landscape.

Other notable landmarks and attractions include Nelson's Anchorage, The 100 Ton Gun, the Alameda Wildlife Conservation Park, Grand Casemates Square, the Lighthouse at Europa Point, O'Hara's Battery, A City Under Siege Exhibition, the Moorish Castle, and Saint Michael's Cave. The site also indicates property listings, highlighting residential aspects of the territory. However, the specifics of the soil-eating study remain unelaborated, with the exact methodology and findings not publicly detailed in the provided context.
