>Ironically, their paper arrived only months after a study co-authored by Viswanathan, da Luz and Raposo showed a catastrophic error in Viswanathan’s original albatross study. The wet/dry sensors they had relied on weren’t dry only when the birds flew: They were also dry when the albatrosses sat on their nests. Some of the longest “flights” in the data set might have actually been protracted visits to the birds’ nests. The study also criticized certain analytical techniques and claimed that albatrosses don’t do Lévy walks after all, and that it was unclear whether many species did.
