Sex determination of individuals is often required for ecological and behavioural studies but
is difficult to carry out in the field for species that are only slightly dimorphic. To address this …

ABSTRACT A field technique to identify sex is critical for facilitating conservation of species
where declines are potentially unequal between the sexes. Although morphometrics are …

Morphometric data on 99 adult and 13 juvenile Yellow-faced Honeyeaters Lichenostomus
chrysops that were independently sexed using molecular techniques were analysed to …

The article focuses on the ecological data of sexual dimorphism in the crescent honeyeater
bird, Phylidonyris pyrrhoptera, at the Cromer Conservation Park and Parndana in South …

Male and female birds often tend to differ with respect to one or more morphological
measure ments (eg Rooke 1976; McFarland 1986; Rogers et al. 1986; Pyke and Armstrong …

Sexual dimorphism in birds may express itself as differences in body size, plumage, color
and/or behavior. Many species are monomorphic in color, which makes sex determination …

In many species of bird, the sexes look similar but one sex is larger than the other. When a
series of measurements is available from unsexed samples of such species, a situation that …

Many petrels show no obvious sex-linked dimorphism in plumage or size and consequently
many researchers fail to sex the living individuals they study. Several methods of sex …

Abstract· Sexual size dimorphism is a widespread pattern among birds, but has remained
untested for many Neotropical species. Here we examine sexual differences in a relatively …

Whilst the sexes of adult hihi (Notiomystis cincta) are easily distinguished by their dim orphic
plumage, male and female nestling and juvenile hihi appear very similar. Hihi is a …
