Morphometric data on 99 adult and 13 juvenile Yellow-faced Honeyeaters
Lichenostomus chrysops that were
independently sexed using molecular techniques were analysed to investigate size dimorphism between the sexes.
Our results support previous studies that have demonstrated Yellow-faced Honeyeaters are sexu ally dimorphic
in size, with males being the larger sex. Discriminant analyses of morphometric data were used to develop a
simple method for sexing adult Yellow-faced Honeye aters in the hand. As five observers collected the
measurements our sexing criteria are conservative and should have wide application for field ornithologists working
on the species.
