Abstract
The principal metabolite of DDT, p,p''-DDE, is responsible for thinning and other structural changes in California condor eggshells. The presence of DDE in thin eggs is verified, and the contribution of the DDT syndrome to lowered nesting success is suggested. Comparisons are made to the changes induced by the experimental feeding of DDE to the structure of eggshells of another falconiform species, the American Kestrel (Falco sparverius). Scanning electron microscopic evidence is presented.This publication has 1 reference indexed in Scilit:
