Mercury levels were determined in feathers from 83 birds belonging to 18 species (eight families), all collected from the northern region of Iran. Mercury levels were evaluated in relation to taxonomic affiliation and feeding strategies. Mercury levels in the feathers were between 0.05 ± 0.01 and 1.10 ± 0.15 μg g(-1) dry weight, and there was a significant effect of taxonomic groups (p < 0.05). The highest mercury levels were found in Accipitridae, and mercury was not detected in the family Upupidae. The pattern for mercury levels was Accipitridae > Pelecanidae > Sternidae > Ardeidae > Anatidae > Rallidae > Phasianidae (p < 0.05). Significant differences (p < 0.05) in the mean mercury levels were found among species as a function of feeding method and trophic level. Mercury levels were highest in the carnivorous species and lowest in the herbivorous species. Mercury levels in feathers of birds in this study were generally below the thresholds reported to affect reproduction.
对来自伊朗北部的83只分属于18个物种（8个科）的鸟类羽毛中的汞含量进行了测定。根据分类归属和取食策略对汞含量进行了评估。羽毛中的汞含量在0.05±0.01至1.10±0.15微克/克干重之间，分类群存在显著影响（p<0.05）。汞含量最高的是鹰科，戴胜科未检测到汞。汞含量模式为：鹰科>鹈鹕科>燕鸥科>鹭科>鸭科>秧鸡科>雉科（p<0.05）。根据取食方式和营养级，不同物种的平均汞含量存在显著差异（p<0.05）。肉食性物种的汞含量最高，草食性物种的汞含量最低。本研究中鸟类羽毛中的汞含量一般低于据报道会影响繁殖的阈值。
