Trash on the Menu:Patterns of Animal Visitation and Foraging Behaviour at Garbage Dumps
Summary
Researchers monitored 32 bird and mammal species visiting garbage dumps near a forested area in India, documenting plastic consumption behavior and the risk of injury or toxin exposure. The study shows that wildlife near human settlements routinely encounter and ingest plastic waste.
Garbage accumulation around terrestrial nature reserves poses a risk to many species. We monitored animal visitation patterns and foraging behaviour at garbage dumps near a forested area in Uttarakhand Himalaya, India, to examine plastic consumption by animals. We recorded 32 species of birds and mammals visiting garbage dumps and classified them as 'peckers', 'handlers' and 'gulpers' based on their foraging behaviour. Gulpers (carnivores and ruminants) were observed feeding more frequently and spent longer durations (3.8 0.2 min) at garbage dumps. Our results highlight the importance of at-source segregation of waste to prevent wild and domestic animals from ingesting hazardous wastes, including plastics at garbage dumps.
