安大略西北部秃鹰的繁殖量从1966年每个繁殖区1.26只秃鹰幼崽下降到1974年的0.46只，然后增加到1981年的1.12只。DDE在变质蛋中的残留量呈显著的负相关，证实了该毒物在种群水平上对秃鹰繁殖的影响以及禁用DDT的有效性。秃鹰从DDE污染中恢复的速度似乎比预期的要快得多。
Reproduction of bald eagles in northwestern Ontario declined from 1.26 young per breeding area in 1966 to a low of 0.46 in 1974 and then increased to 1.12 in 1981. Residues of DDE in addled eggs showed a significant inverse relation, confirming the effects of this toxicant on bald eagle reproduction at the population level and the effectiveness of the ban on DDT. The recovery from DDE contamination in bald eagles appears to be occurring much more rapidly than predicted.
