Washington, DC–(ENEWSPF)–September 18, 2013. DDT, a pesticide banned in 1972, is behind the mystery surrounding the reproductive problems of dozens of endangered condors. This is according to a peer-reviewed paper written by 10 condor experts, including biologists from the Los Angeles and Santa Barbara zoos and the U.S. Fish and Wildlife Service. The researchers, who spent six years studying the reproductive problems, including eggshell thinning, in California condors have “established a strong link” to DDT in the birds’ food source.
