Offshore refuges support higher densities and show slower population declines of wintering Ruddy Turnstones Arenaria interpres: a comment on the log-transformation of bird densities

Log transformations of density values in the form log(count)/log(area), as used in a recent paper in this journal, do not preserve the rank order of the untransformed density values and are dependent on the units used for area. The appropriate log transformation of density is log(count/area).
