The distribution of masses of Lesser Honeyguides in the Western Cape. between the means for the sexes would produce roughly the same probability of misclassification. The percentage of females in the sample of Lesser Honeyguides caught in mist-nets was estimated to be 73% (Table 1). The Lesser Honeyguides were a by-catch, not a target species, and no attempts were made to attract them to the mist-netting sites by providing wax. It therefore seems likely that female Lesser Honeyguides are more mobile than males, and more likely to get caught in randomly (for them) positioned mist-nets. This is consistent with the biology of the species; male Lesser Honeyguides spend long periods of time stationary at "call-sites", the traditional singing perches where mating takes place (Ranger 1955), while females move extensively while searching for the nests of their hosts (Payne 1992). The distribution of mass showed no bimodality (Fig. 3), and had a mean of g and standard deviation g (n = 69). Maclean (1993) reported a mean mass of g.
