    Abstract

    We applied discriminant analysis to morphometric data from Chinstrap Penguins (Pygoscelis antarctica) to obtain a function that can be used to predict sex. The function correctly classified 95% of 55 individuals. Bill depth was the most important discriminating variable, with males having deeper bills.
