摘要翻译:
爱德华兹等人。[Nature 449,1044-1048(2007)]回顾了关于游荡信天翁飞行持续时间频率分布的幂律的著名研究,并得出结论,没有一个L\'evy过程能够以更高的分辨率模拟最近的观测结果。在这里,我们表明这种重新分析遭受了概念上的误解,新的信天翁数据仍然与生物飞行一致。

英文摘要:
Edwards et al. [Nature 449, 1044-1048 (2007)] revisited well-known studies reporting power-laws in the frequency distribution of flight duration of wandering albatrosses, and concluded that no L\'evy process could model recent observations with higher resolution. Here we show that this re-analysis suffers from a conceptual misunderstanding, and that the new albatross data remain consistent with a biological L\'evy flight.
