ABSTRACT:
A recent publication[1] revisited well-known studies reporting power-laws in the frequency distribution of flight duration of wandering albatrosses and concluded that no Lévy process could model recent observations with higher resolution. Here we show that this re-analysis1 suffers from a conceptual misunderstanding, and that the new albatross data remain consistent with a biological Lévy flight.
