Every bald eagle found dead in the U.S., between 1961-1977 (266 birds) was analyzed by U.S. Fish and Wildlife Service biologists who reported no adverse effects caused by DDT or its residues.

After 15 years of heavy and widespread usage of DDT, Audubon Society ornithologists counted 25 percent more eagles per observer in 1960 than during the pre-DDT 1941 bird census.

Many experiments on caged-birds demonstrate that DDT and its metabolites (DDD and DDE) do not cause serious egg shell thinning, even at levels many hundreds of times greater than wild birds would ever accumulate.

No significant correlation between DDE residues and shell thickness was reported in a large series of bald eagle eggs.

In congressional testimony, Charles Wurster, a biologist for the Environmental Defense Fund, noted the abundance of birds during the DDT years, referring to "increasing numbers of pheasants, quail, doves, turkeys and other game species."

Now how about disputing the relevant parallel between the DDT scare and AGW hoax  ?
