Abstract

In a recent publication, Mayberry et al. (2017) presented a method for estimating western grey kangaroo age from the weights of dried eye lenses. The drying conditions are inadequate and may lead to erroneous age estimates. It is suggested that well documented methods in general use be used for future studies.

Additional keywords: lens dry weight.
