Abstract: Addled and viable Great Horned Owl eggs were compared in terms of pesticide levels egg and eggshell parameters. Addled eggs were generally larger in linear measurement and weight than viable eggs. Thickness index values for addled eggs were lower than those for viable eggs and for those previously reported by Osborne and Winters (1977) and Anderson and Hickey (1970). All egg samples analyzed for pesticide residues contained moderate amounts of DDE, PCB, dieldrin, heptochlor epoxide and oxychlordane, while some samples contained measurable amounts of HCB and TDE.
