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.
安大略省西北部白头海雕的繁殖数量从1966年每个繁殖区域1.26只幼鸟下降到1974年的低点0.46只，然后在1981年增加到1.12只。腐坏卵中的滴滴滴残留量呈现出显著的负相关关系，证实了这种有毒物质在种群水平上对白头海雕繁殖的影响以及禁止使用滴滴涕的有效性。白头海雕从滴滴滴污染中的恢复速度似乎比预期快得多。
