Chemicals that haven't been manufactured in the U.S. for years or even decades are still turning up in the bodies of migratory terns in the Great Lakes region, a new study finds. For all these birds, coastal areas are vital. } }); Your opinions are important to us. Thousands of raptors, waterfowl, and wetland birds rely on the Great Lakes systems for safe nesting grounds. The piping plover (Charadrius melodus), a sparrow-sized, coastal dwelling bird, is a true North American treasure.Found only along the Atlantic coast, surrounding the Great Lakes, and on the alkalai flats of the northern Great Plains, the piping plover derives its name from the bell-like whistled peeps it uses for communication. if(currentURL.toLowerCase().indexOf("secoast") != -1) { They are good divers, but usually feed by dabbling or tipping rather than submerging. He notes that the smallest chicks the team studied harbored higher concentrations of the chemicals than older birds and adults, indicating that the compounds are being passed from parent to progeny. They also found the same pollutants in emerald shiners, the birds’ main food source in the Great Lakes, indicating that the migratory birds were getting at least some of their chemical load in the Great Lakes region and not picking it up elsewhere. "We can't say that all the chemicals we're seeing in the birds are coming from the Great Lakes, as the birds migrate and could be accumulating these compounds in other places along their migration route, too," Travis says. Scientists discovered all three kinds of chemicals in the organs of over two dozen common terns in breeding grounds along the Niagara River and the shore of Lake Erie. © Copright 2018 The Nature Conservancy. “We can’t say that all the chemicals we’re seeing in the birds are coming from the Great Lakes, as the birds migrate and could be accumulating these compounds in other places along their migration route, too,” Travis says.

That one of the best ways to do this is by supporting the Western Great Lakes Bird and Bat Observatory ", More information: ", He adds, however, that, "One positive outcome of the study is that we only see the metabolite of DDT, called 'DDE,' in the fish. Though a 2020 study published in Environment International focuses on common tern chicks, juveniles and adults, University at Buffalo and SUNY Buffalo State scientists have begun work on a study examining the levels of pollutants in common terns and other wild aquatic birds’ eggs. Chemicals that haven't been manufactured in the U.S. for years or even decades are still turning up in the bodies of migratory terns in the Great Lakes region, a new study finds.

The research highlights the risks associated with legacy contaminants, as well as the urgency of protecting the environment as new issues surrounding other classes of persistent chemicals, such as per- and polyfluoroalkyl substances (PFAS), emerge. The steady improvement in the water quality of the Great Lakes represents one of the real environmental success stories of recent decades. $('#nav li').hover( Your email address is used only to let the recipient know who sent the email. A key component of the Great Lakes initiative is the improvement of stopover habitat for migratory birds. } Millions of migratory birds depend on coastal habitats along the Great Lakes for shelter, rest, and nourishment for their long journeys. The research focused on three types of compounds: polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyls (PCBs), and the breakdown products, called metabolites, of dichlorodiphenyltrichloroethane (DDT). Our Migratory Birds Program includes a team of biologists, permits specialists, and the Upper Mississippi River and Great Lakes Region Habitat Joint Venture staff who work to sustain healthy populations as well as suitable habitat for birds throughout the Midwest Region and to migration … The Joppa Flats Education Center established its Bird Banding Station on Plum Island, part of the Parker River National Wildlife Refuge, in May 1998. "These chemicals are still there. The study was published online in the journal Environment International and will appear in its November issue. Legacy pollutants found in migratory terns in Great Lakes region. But the researchers say it’s highly likely other migrating shorebirds throughout the Great Lakes are also polluted by the trio of chemicals. Note: Environment International, Provided by Hawk Ridge Bird Observatory is a 501 (c) 3 nonprofit organization. Migration is a spectacle so big that it shows up on weather radars throughout the month of May, but undetected by most in their everyday lives. The juxtaposition of the two flyways, paired with our Great Lakes habitat, makes Michigan an outstanding place to observe a variety of migratory birds, from waterfowl to hawks to shorebirds to neo-tropical migrants. Production of PCBs, once widely used as a coolant or insulating fluid in electrical transformers and capacitators, ended in the country in 1979. These substances can alter development and neurological processes and could cause deformities, cancers and impaired behavior.". Fish & Wildlife … The population in the Great Lakes went from a few thousand birds in the 1970s to a peak of 115,000 nesting pairs around 2000.

Yet, while we know Great Lakes coasts are important, quantifying and identifying priority habitats used during migration, so that we can better protect them, is a major challenge. "But the specific types of PCBs and PBDEs we're seeing in the emerald shiners is similar to what we're seeing in the birds. The steady improvement in the water quality of the Great Lakes represents one of the real environmental success stories of recent decades. Sales of PBDEs, a class of flame retardants used in car seats, carpet padding, mattresses and many other household products, were phased out in the U.S. in 2013. More than 60 bird species breed here, including the rare seaside sparrow and the least tern. But the giant inland seas’ ecosystem now faces a new threat, this one coming from advocates of renewable energy. The Great Lakes in general are hugely important for migratory birds because they act as a funnel for birds that are migrating through our area."

Given the ecological, economic, and cultural importance of Great Lakes migratory birds, combined with potential negative impacts of land use change, including wind energy and other commercial development, it is essential that we work to address this challenge. The amount of water entering and leaving the lakes each year is less than one percent of the total in the lakes. lands and waters for nature and people. Other birds, many of which migrate on broader routes, also congregate in large numbers near the coast due to the relatively abundant food sources, including aquatic insects. Millions of waterfowl, shorebirds, water birds, and raptors utilize the region’s diverse habitats on their journeys, including open waters, agricultural fields, mudflats, shrublands, marshes, coastal wetlands, grasslands, and forests. } To find out more, read our Privacy Policy. $('ul', this).slideUp(100); Despite their great size, the Great Lakes are actually very vulnerable to pollution.

The source of toxic pollutants includes decades of industrial waste, raw sewage overflows, runoff from cities, and mining operations. "They tax the terns' livers as they have to try and get rid of these pollutants, but the bioaccumulative nature of PCBs, PBDEs and DDEs means that the birds will not be able to fully detoxify themselves, and that they will pass part of their body-load to the next generation. Holding 20% of the world’s fresh water within more than 10,000 miles of shoreline, the Great Lakes are a globally significant ecosystem. if(currentURL.toLowerCase().indexOf("lowerms") != -1) { These migration rest stops, also known as “stopover sites”, provide shelter and nourishment to hundreds of different bird species, helping to ensure the success of these migrations, which contribute to the region’s biodiversity, and boost economies and recreational opportunities via hunting and bird watching. With PCBs, for example, they haven't been produced in the U.S. for a long time now, but you can still find them in the environment, in sediments and in water. Dabbling ducks are typically birds of fresh, shallow marshes and rivers rather than of large lakes and bays. Decades ago the Cat Island chain in Lake Michigan’s Green Bay was a bird haven.
