Bald Eagle Watch Month: How litter can endanger birds

There is nothing quite like catching a glimpse of a bald eagle soaring over the trees. Unfortunately, habitat destruction and degradation, illegal shooting, litter and contamination of its food source all led to the decline in population of our national symbol roughly 40 years ago. The once endangered species has made a remarkable comeback due to strong conservation efforts, protective legislation and increased awareness. Arkansas is home to a large number of the species, making the sport of watching them increasingly popular across The Natural State. While conservation efforts are widespread across the country, it is important for us to understand what we can do to ensure the bald eagle’s safe future. Here are some contributing factors that led to the bald eagle’s decline, and ways that we can ensure the bald eagle’s safety for years to come:

BIG, BAD Balloons

Despite the innocence and beauty of balloons, they have unintended dangerous consequences for birds and other wildlife. The natural latex used is biodegradable and environmentally safe, yet the balloons are treated with multiple preservatives and chemicals to safeguard against bacterial decomposition. Aside from the chemical dangers, balloons can also cause starvation and tangling among the bird populations. Through inadvertent ingestion, birds mistake the balloon for food and consequently cannot digest the latex. Therefore, the bird is unable to take in enough nutrition to survive, thus starving. If the balloons released have ribbon or string attached, tangling is a huge threat as well. Tangle injuries can include malformed nestling growth, open wounds from chafing as the tangle tightens or mobility restriction of the legs, wings or bill, all making the bird more vulnerable to predators and infections.

Perilous Plastic

In many areas around the globe, birds inadvertently feed on plastic floating on the water mistaking it for food, which can directly lead to death and even the death of their young. Large plastic debris, such as bottles, has major effects on bird populations as it can strangle them and can also transport alien species to new waters. Millimeter-sized plastic pellets (what is used in most plastic production) soak up toxic chemicals from water, poisoning the creatures that swallow them. Because these plastic pellets are magnets for toxic chemicals they effectively become poison pills. Japanese researchers found that concentrations of these chemicals were as much as a million times higher than in the water. Seeing that the bald eagle’s primary food source consists of water prey, they are incredibly susceptible to the dangers of plastic litter.

What You Can Do
Knowing what we do about the decline of the bald eagle population in America and the factors contributing to it, we must all make the conscious effort to be proactive in the conservation of our national symbol. By simply reducing our use of disposable plastic products, being mindful and reminding others of the dangers of plastic and litter debris, and opting out of celebratory balloon releases, we can continue to lead the way in the conservation of the bald eagle. If you must use plastic, please remember to dispose of your plastic products – particularly bottles – properly, by either recycling responsibly or placing then into waste receptacles. Taking these actions will provide us with an abundance of opportunities to participate in Bald Eagle Watch Month’s to come.
