One small piece of litter may not seem like much, but even minor amounts of trash can be devastating to birds in several ways. Understanding how litter hurts birds can lead to more responsible trash disposal and other measures to keep the environment clean and suitable for birds and other wildlife.
Types of Litter That Hurts Birds
All types of litter can have detrimental effects on birds, though some of the most insidious trash is also some of the most common, including:
- Rotten, discarded food
- Lead-based items, such as bullet casings or fishing sinkers
- Fishing line, long ribbons, or kite string
- Discarded plastic of all shapes and sizes
- Abandoned or runaway balloons
- Oil-based liquid litter, such as spilled motor oil or kitchen grease
While these items may be the most dangerous, all litter has negative consequences for the birds.
How Litter Affects Birds
Depending on the specific type of litter, it can affect birds in several ways:
- Digestive Blockage: Plastic litter or bits of rubber balloons, especially small, brightly colored pieces, may look irresistible to foraging birds, but it cannot be digested. Instead, it will stay in the digestive tract, blocking the passage of food and eventually starving the bird because it will not be able to eat due to the amount of litter it has ingested.
- Injuries: Sharp shards of glass or plastic can injure birds that swallow them, cutting into the throat or intestines and causing hemorrhages. Fishing line or kite string can become wrapped around birds and cause cuts or amputations to the wings, legs, feet, or neck. These injuries can prove fatal. If these materials are used in nesting, hatchlings can be strangled or injured.
- Plumage Disruption: A bird’s plumage must be precisely aligned to provide proper insulation and easy flight, and even a small amount of oil or grease can harm a bird. Waterfowl, in particular, are susceptible to oiling that can lead to hypothermia. As birds preen to remove the oil, ingesting the toxin can also lead to poisoning.
- Habitat Loss: Heavily littered areas are unsuitable for nesting, feeding, or shelter, forcing birds to seek out less desirable areas with greater competition for necessary resources. Litter can also contaminate water sources, and the polluted ground is less likely to support insects or seed- or fruit-bearing plants for food sources.
- Attracting Predators: Discarded food that is left as litter can attract predators such as rats, feral cats, raccoons, and foxes that will also prey on birds or nests. Rotting litter can also give rise to bacteria that will cause illness in birds, or it may attract ticks or mites that can be detrimental pests.
How You Can Help
Thousands of birds die each year because of littering effects, but fortunately, even a few small steps can help protect birds. Easy ways anyone can help include:
- The Three Rs: Reduce, reuse, and recycle. The less litter is produced, the less there will be to affect the birds. This includes recycling at work, schools, and in the home as well as promoting community and retail programs to reduce waste materials.
- Pick Up Litter: When out for a walk, pick up litter you find or organize a litter clean-up event as a service project. This is especially critical in refuges, nature preserves, and other essential habitats, but is useful wherever litter is picked up.
- Dispose of Trash Properly: Discard trash in tightly closed bags that are less likely to break and scatter litter, and be sure trash cans are positioned so they will not tip or spill. At public events, always use available trash cans to get rid of litter and debris. Even small pieces of litter, such as discarded gum, should be disposed of properly.
- Be a Good Example: Share tips with family members, friends, co-workers, and neighbors about how to reduce litter and why doing so is important for all birds and wildlife. Give birthday or holiday gifts to help reduce litter, such as reusable bags or mugs, and always practice litter-reducing habits yourself.
By understanding how litter affects birds and how to take simple steps to reduce the problem, it is possible to protect birds and provide a beautiful, litter-free environment for both wildlife and humans to enjoy.
