Pylons of utility lines are commonly used by breeding birds as structures for supporting their nests. Nesting near power lines, however, exposes adult birds and their offspring to the electric and magnetic fields (EMFs) produced by the current. Therefore, we searched for possible relationships between the magnetic field (MF) magnitude experienced by wild kestrel (Falco tinnunculus) nestlings grown on pylons and different health-related variables: body condition, serum concentration of carotenoids, reactive oxygen metabolites (ROMs; marker of early oxidative damage), serum anti-oxidant capacity (OXY), and the ratio between ROMs and OXY (index of oxidative stress). No significant relationships were found between the MF magnitude or squared MFs and any of the variables considered. Comparisons with values recorded in nestlings from non-exposed nests seem to confirm the absence of any effect of exposure to MFs produced by power lines on the variables considered.
电线杆通常被繁殖鸟类用作支撑巢穴的结构。然而，在电线附近筑巢会使成年鸟类及其后代暴露于电流产生的电场和磁场（EMF）中。因此，我们研究了在电线杆上生长的野生红隼（Falco tinnunculus）雏鸟所经历的磁场（MF）强度与不同健康相关变量之间的可能关系：身体状况、血清类胡萝卜素浓度、活性氧代谢产物（ROMs；早期氧化损伤的标志物）、血清抗氧化能力（OXY）以及ROMs与OXY的比值（氧化应激指数）。未发现MF强度或MF平方与所考虑的任何变量之间存在显著关系。与未暴露巢穴雏鸟记录值的比较似乎证实，暴露于电线产生的MF对所考虑的变量没有任何影响。
