Dominant females have brighter ornamentation in a sexually dimorphic lekking species
Males often exhibit elaborate ornamentation that contributes to their fitness. Similarly,
females can also exhibit elaborate ornamentation, but we have a relatively limited …

Circulating testosterone and feather-gene expression of receptors and metabolic enzymes in relation to melanin-based colouration in the barn owl
Abstract Knowledge of how and why secondary sexual characters are associated with sex
hormones is important to understand their signalling function. Such a link can occur if i) …

Blood parasite infection differentially relates to carotenoid‐based plumage and bill color in the American goldfinch
Male and female American goldfinches (Spinus tristis) express condition‐dependent
carotenoid‐based plumage and bill coloration. Plumage color is relatively static, as …

Intraspecific variation and directional casque asymmetry in adult southern cassowaries (Casuarius casuarius)
The cranial casques of modern cassowaries (Casuarius) have long intrigued researchers;
however, in‐depth studies regarding their morphological variation are scarce. Through …

Biomechanics of the peafowl's crest reveals frequencies tuned to social displays
Feathers act as vibrotactile sensors that can detect mechanical stimuli during avian flight
and tactile navigation, suggesting that they may also detect stimuli during social displays. In …

Condition-dependent mate assessment and choice by peahens: implications for sexual selection
Condition-dependent mate choice is thought to affect the strength and direction of sexual
selection. Although there is ample evidence of this from studies that experimentally …

It isn't always sexy when both are bright and shiny: considering alternatives to sexual selection in elaborate monomorphic species
KA Tarvin, TG Murphy - Ibis, 2012 - digitalcommons.trinity.edu
Since the dawn of abstract thinking, humans have wondered about the seemingly
unnecessary elaborate ornamentations of birds. Gaudy colours, cumbersome tails, complex …

Odor is linked to adrenocortical function and male ornament size in a colonial seabird
HD Douglas III, AS Kitaysky, EV Kitaiskaia - Behavioral Ecology, 2018 - academic.oup.com
Crested auklets (Aethia cristatella), colonial seabirds of Alaska and Siberia, emit a citrus-like
odorant from wick-like feathers. We examined whether the odorant emission is linked to …

Multi‐functional crest display in hoopoes Upupa epops
Animals can engage in visual displays, which may target conspecifics, heterospecifics or
both. Here we studied the function of the flamboyant crest‐raising display of hoopoes Upupa …

Peafowl antipredator calls encode information about signalers
JL Yorzinski - The Journal of the Acoustical Society of America, 2014 - pubs.aip.org
Animals emit vocalizations that convey information about external events. Many of these
vocalizations, including those emitted in response to predators, also encode information …
