Evolution and functional significance of sexual displays in bowerbirds (Ptilonorhynchidae)
TLDR
Examination of display evolution including co-evolution of visual spectral sensitivity and color displays in the context of sensory drive theory, interspecific learning of behavioral displays and hybridization, and the significance of collected objects used in display reveal that bowerbirds are sensitive to relatively short wavelength ultraviolet light which suggests that they may use this waveband in sexual communication.
Do male Great Bowerbirds (Ptilonorhynchus nuchalis) minimise the costs of acquiring bower decorations by reusing decorations acquired in previous breeding seasons?
TLDR
Data collected during a 5-year field study of the Great Bowerbird suggest there are costs associated with acquiring decorations, and males reuse decorations to minimise costs.

TLDR
It is shown that if males compete for resources used in sexual displays, intense female preference for high–quality displays can lead to poorer prospects for efficient choice by females, and the evolution of female choice may have a self–limiting nature when it poses a selection pressure on male resource acquisition.
Multiple sexual ornaments in satin bowerbirds: ultraviolet plumage and bowers signal different aspects of male quality
TLDR
The findings support the multiple messages hypothesis of multicomponent signals: Female satin bowerbirds should assess both male and bower features to choose the highest quality mates.
Fidelity to Bowers, Adult Plumage Acquisition, Longevity and Survival in Male Golden Bowerbirds Prionodura newtoniana
TLDR
Male Golden Bowerbirds Prionodura newtoniana were studied over 20 consecutive seasons in rainforest on Paluma Range, north Queensland, indicating a mean expectancy of further life after initial capture of 10.9 years.
Archbold's Bowerbird Archboldia papuensis (Ptilonorhynchidae) Uses Plumes from King of Saxony Bird of Paradise Pteridophora alberti (Paradisaeidae) as Bower Decoration
TLDR
Predation by Micronesian Starlings during human related disturbances may have contributed to losses of Black Noddy breeding success in conjunction with human disturbance.
Plumage based classification of the bowerbird genus Sericulus evaluated using a multi-gene, multi-genome analysis.
An Attempt to Explain Visual Aesthetic Appreciation.
We suggest an evolutionary based explanation for why humans are preoccupied with aesthetic aspects of visual input. Briefly, humans evolved to be swayed by positive and negative feelings in the form…
