Sexual selection in many animal species favors the evolution of elaborate courtship traits. Such traits might help signalers convey, and receivers discern, information about signaler quality; or they might be favored by perceptual or aesthetic preferences for elaborateness or beauty [1-3]. Under either scenario we expect sexual trait elaboration to be countered by proximate constraints rooted in animals' morphology, physiology and phylogenetic history [3,4]. During expeditions to a montane… Expand
Song amplitude and population density in two sympatric warblers, Phylloscopus schwarzi and P. fuscatus
TLDR
The analysis of video-recordings revealed the larger extension of the neck region (‘throat sac’) in Radde’s Warbler than in Dusky Warbler, which was hypothesised to be responsible for the louder song of Raddes Warbler. Expand
Female signal jamming in a socially monogamous brood parasite
https://doi.org/10.1016/j.anbehav.2020.10.011 0003-3472/© 2020 The Association for the Study of A Acoustic signalling is vital to courtship in many animals, yet the role of female vocalizations isExpand
Echolocation at high intensity imposes metabolic costs on flying bats
TLDR
It is demonstrated that above 130 dB sound pressure level (SPL, at a reference distance of 10 cm), the costs of sound production become exorbitantly expensive for small bats, placing a limitation on the intensity at which they can call. Expand
Genomic heritability of song and condition in wild singing mice
TLDR
The estimate of genomic heritability of advertisement song and body condition in a wild population of singing mice suggests a comparable genetic correlation that merits further study, and illustrates how advances in genomics and quantitative genetics can be integrated in free-living species to address longstanding challenges in behavior and evolution.

How Loud Can you go? Physical and Physiological Constraints to Producing High Sound Pressures in Animal Vocalizations
Sound is vital for communication and navigation across the animal kingdom and sound communication is unrivaled in accuracy and information richness over long distances both in air and water. TheExpand
Vestibular suppression of normal bodily sounds
TLDR
Chewing is known to cause a stapedius reflex which suppresses internal sounds to optimize audition of external sounds, while at the same time suppressing Vestibular stimulation, which serves to optimize the sensitivity of the vestibular system, in order that it may respond precisely to a threat.

Rock Sparrow Song Reflects Male Age and Reproductive Success
TLDR
It is shown that song performance reflects age and reproductive success in the rock sparrow (Petronia petronia), and high-amplitude songs correlated with paternity loss in the own nest, suggesting that in this species song amplitude is not an indicator of male quality but high-intensity songs may be rather a response to unfaithful social mates.

Physiological constraint on acrobatic courtship behavior underlies rapid sympatric speciation in bearded manakins
TLDR
It is shown how muscle specialization played an instrumental role in the sympatric speciation of a manakin genus, illustrating that muscle specializations fostered divergence in courtship display speed, which may generate assortative mating. Expand
Vocal Performance and Sensorimotor Learning in Songbirds
Since the pioneering studies of William Thorpe and Peter Marler, songbirds and their songs have served continuously as an inspirational muse to behavioral biologists (Catchpole and Slater, 2008;Expand
Female mate choice based upon male motor performance
Our goal in this essay is to review the hypothesis that females choose mates by the evaluation of male motor performance. We define motor performance as vigour, the ability to perform energeticallyExpand
Chapter 1 Environmental Acoustics and the Evolution of Bird Song
TLDR
This chapter argues that the combination of environmental constraints on signal transmission, noise levels, and the use of signal degradation as a distance cue need mutual consideration to gain a more thorough understanding of the astounding variety of avian song and the many different ways in which birds use it. Expand
Songbirds tune their vocal tract to the fundamental frequency of their song.
TLDR
Through x-ray cinematography of singing birds, it is shown that birdsong is accompanied by cyclical movements of the hyoid skeleton and changes in the diameter of the cranial end of the esophagus that maintain an inverse relationship between the volume of the oropharyngeal cavity and esophagi and the song's fundamental frequency. Expand
Vocal tract resonances in oscine bird sound production: evidence from birdsongs in a helium atmosphere
TLDR
Not only does the songbird's vocal tract act as an acoustic filter, but its filter characteristics are actively coordinated with the output of the syrinx, suggesting that birdsong and human phonation are more analogous than previously thought. Expand
Chapter 5 Vocal Performance and Sensorimotor Learning in Songbirds
Abstract This chapter addresses the interplay of vocal performance, sensorimotor learning, and vocal evolution in songbirds. Vocal performance is increasingly recognized as an influential factor inExpand
