    In the Fan-tailed Warbler population, males were found to have significantly longer wings than females. There was no overlap, except two adult males with the shortest wings and one female with the longest ones, contrary to the observations of Gauci & Sultana (1981). The same was also true for juveniles, there was no overlap. There were also significant differences in body weight and bill length between adult males and females, however, these measurements were not used for sexing because of overlapping. In juveniles, body weight and bill lenght did not differ significantly between the sexes.
