"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.

The amount of water entering and leaving the lakes each year is less than one percent of the total in the lakes. Authors included University at Buffalo chemists Diana Aga and Steven Travis, and SUNY Buffalo State biologist Alicia Pérez-Fuentetaja. the Science X network is one of the largest online communities for science-minded people. The findings illustrate how household and industrial chemicals have become ubiquitous in the environment, where they can endure for many years, posing risks to wildlife. For example, many raptor species, such as broad-winged hawks and red-tailed hawks, typically concentrate along narrow corridors that follow the shoreline. The new study shows how long-banned chemicals continue to jeopardize the health of Great Lakes ecosystems. And use of DDT, an insecticide, has been prohibited in the U.S. for almost half a century, since 1972.

Thousands of raptors, waterfowl, and wetland birds rely on the Great Lakes systems for safe nesting grounds. 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. Included within the ACEC is the 2900-acre Parker River National Wildlife Refuge, known as an important site on the Atlantic Fly-way Migration route. Despite their great size, the Great Lakes are actually very vulnerable to pollution. These substances can alter development and neurological processes and could cause deformities, cancers and impaired behavior.". Hawk Ridge Bird Observatory P.O. The levels of PCBs and PBDEs in the birds were high enough to potentially harm the birds' health and affect population recovery, the authors write in their paper. 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.
