<p><span>Reproductive performance was measured for 126 days in twelve pairs of ring doves (</span><i>Streptopelia risoria</i><span>) fed a diet containing 40 ppm of p,p'-DDE and in twelve other pairs given untreated food.

Hatchability was also lower but not significantly so. Control birds nested forty-nine times during the study, laying two eggs in each clutch. DDE-treated birds nested only thirty-three times, laying an average of 1·7 eggs/clutch. The combined effects of DDE on reproduction resulted in only ten young being successfully raised by DDE-treated pairs versus thirty-five being raised by controls.</span></p>
