Aerial displaying is a flamboyant part of the sexual behaviour of several volant animal groups, including birds. Nevertheless, little attention has been focused on identifying correlates of large-scale diversity in this trait. In this study, we scored the presence and absence of aerial displays in males of 1732 species of passerine birds (Passeriformes) and employed Bayesian phylogenetically informed mixed models to test for associations between aerial displays and a set of life-history and…

Habitat structure drives the evolution of aerial displays in birds

A continent-wide phylogenetic comparative analysis found that aerial displays are seven times more likely to evolve in open habitats than in forests, likely as a result of physical properties that allow aerial displays to transmit more broadly inopen habitats.

Conspicuous sexual signals in a socially monogamous passerine: the case of neotropical Blue-black Grassquits

The data suggest that females have an active role in obtaining extrapair fertilizations, but appear to be indiscriminate in their choice of extrapair males, and hypothesize that small male size may be driven by female choice for male motor performance, leading to better performance by small males in intrasexual interactions involving flight within confined spaces.


It is suggested that sexual selection has had a major influence on sexual size dimorphism in Charadrii, whereas divergence in the use of feeding resources while breeding was not supported by analyses.

The importance of white on black: unmelanized plumage proportion predicts display complexity in birds

It is hypothesized that, given that the efficacy of visual displays basically depends on conspicuousness and level of performance, species with low levels of conspicuousness may be forced to perform more complex varieties of a given display to get the same signal efficiency than other more conspicuous species.

Habitat structure drives the evolution of aerial displays in birds.

The influence of habitat structure on the evolution of aerial sexual displays attests to the importance of sensory drive as a deterministic evolutionary force within sexual selection, as opposed to models that assume a purely arbitrary direction of sexual trait evolution.

The results suggest that RSD in hawks, falcons and owls evolved due to natural-selection pressures rather than sexual-selection pressure, consistent with the small-male hypothesis.

The effects of life history and sexual selection on male and female plumage colouration

A new method is used to quantify plumage colour of all ~6,000 species of passerine birds to determine the main evolutionary drivers of ornamental colouration in both sexes, and finds that conspecific male and female colour elaboration are strongly correlated.

Avian body sizes in relation to fecundity, mating system, display behavior, and resource sharing

A comprehensive data set on avian body sizes that would be useful for future comparative studies of avian biology and will function to point out species where baseline data on body size and relevant information on reproduction and behavior are currently lacking or of poor quality, thus stimulating the publication of such data.

Intraspecific sexual selection on a speciation trait, male coloration, in the Lake Victoria cichlid Pundamilia nyererei

It is reported that a male colour trait, which has previously been shown to be important for behavioural reproductive isolation between this species and a close relative, is under directional sexual selection by female mate choice within this species, consistent with the hypothesis that female choice has driven the divergence in male coloration between the two species.
