Reindeer may have deliberately collected ball net in its antlers as animals adapt creatively to littering

A reindeer spotted in Vihti, southern Finland, was photographed with what appears to be a badminton net tangled in its antlers—a striking example of how wildlife interacts with human waste. The image, captured by nature photographer Pike Nuortila in mid-March, has sparked widespread discussion about animals’ adaptability to environmental pollution, reports Finnish broadcaster Yle.

The reindeer was seen among a small herd near a residential property, its antlers entangled with the net. Nuortila shared the photo in a Finnish nature photography group on Facebook, where it drew thousands of reactions. Some commenters noted the same deer had been seen with the net as early as last autumn, suggesting it may have deliberately kept the material.

The observation aligns with known reindeer behaviour during the autumn rutting season, when males intentionally gather objects—such as moss, grass, or even human-made debris—to enlarge their antlers and assert dominance. “It’s quite astonishing to think it might have spent the entire winter with that net,” Nuortila said.

The incident reflects broader concerns about wildlife adapting to human litter. A five-year study by the Finnish Environment Institute (Syke) found that 58 percent of cormorant nests on islands near Helsinki, Kotka, and Porvoo contained waste, 95 percent of which was plastic. Items included ropes, fishing gear, and construction debris.

Research professor Maiju Lehtiniemi noted that some cormorants appeared to deliberately decorate nests with brightly coloured waste, possibly to attract mates. “We wondered if males might be more successful if their nests are well-adorned,” she said.

While such adaptations offer glimpses of resilience, littering remains a severe threat. Discarded fishing nets, hooks, and broken glass can cause slow, painful deaths for birds and marine life. A recent Polish study also found some bird species use cigarette butts in nests, though such cases are rare.

The global scale of plastic pollution is staggering, with millions of tons entering oceans annually—equivalent to 400 Olympic-sized swimming pools. Cigarette butts alone account for an estimated 4.5 trillion pieces of litter each year.
