Sexual signals are often elaborate as a result of sexual selection for signals of individual quality. Contrary to expectation, however, the elaboration of signals such as birdsong is not related to the strength of sexual selection across species. With a comparative study across wood warblers (family Parulidae), we show a compromise between advertising the performance of trills (syllable repetitions) and song complexity, which can result in the evolution of simple, rather than elaborate, song… 
Elaborate visual and acoustic signals evolve independently in a large, phenotypically diverse radiation of songbirds
TLDR
It is found that elaborate visual and vocal sexual signals evolve independently among tanagers, although the relationship between song and plumage complexity varies among subfamilies.
Sexual Selection and the Evolution of Vocal Mating Signals: Lessons from Neotropical Songbirds
TLDR
It is concluded that sexual selection on songs of neotropical birds acts in a manner consistent with present theory, although its study is greatly extending the boundaries of what the authors know about song in fascinating directions.
Multiple signaling functions of song in a polymorphic species with alternative reproductive strategies
TLDR
The results support a multiple messages model for white‐throated sparrow song, in which different song traits communicate discrete information about the vocalizing individual, including fitness, species identity, individual identity, and morph.
Song performance and elaboration as potential indicators of male quality in Java sparrows
TLDR
Contrary to the tradeoffs predicted by previous studies based on other passerine species, trill performance and song complexity, i.e., note repertoire, were positively correlated: males in better condition can sing songs with larger note repertoires and higher trills, which may explain how trills and non-trill notes are both maintained and have co-evolved by sexual selection in Java sparrow songs.
Can simple songs express useful signals for mate choice?
TLDR
This study finds that male wing and tail lengths were positively correlated with early clutch initiation as were songs characterized by short duration and rapid rise to maximum amplitude, which supports the hypothesis that females may judge male quality from quite subtle differences.
Sexual Selection In House Wrens
Signals that require a high degree of skill to produce are expected to honestly indicate signaler quality. In trilled bird song, two parameters that likely reflect performance difficulty are vocal
Song evolution in Maluridae: influences of natural and sexual selection on acoustic structure
TLDR
Variation in song structure across the Maluridae appears to reflect a complex interaction between natural and sexual selection, and the lowest frequencies of song were strongly predicted by body-size, indicating that morphological constraints have also likely influenced acoustic phenotypes.
CORRELATED EVOLUTION OF BEAK MORPHOLOGY AND SONG IN THE NEOTROPICAL WOODCREEPER RADIATION
TLDR
Evidence of a trade‐off between the rate of repetition of song syllables and frequency bandwidths is found, suggesting that ecological selection on beak morphology influences the diversification of woodcreeper songs and indicates a broader role for ecology in avian diversification.
The intensity of male-male interactions declines in highland songbird populations
TLDR
This study illustrates the decline of some trait associated with aggressive territorial behaviours during male-male conflicts along elevation, and points to the allocation in sexual signalling and motor constraints to signal production, as potential mechanisms underlying it.
Song complexity and its evolutionary correlates across a continent-wide radiation of songbirds
TLDR
The largest comparative study on bird song to date is undertaken by exhaustively sampling audio recordings within a large radiation of Neotropical oscines known as tanagers, finding that song and plumage complexity are uncorrelated across all tanagers and also uncor related within eight of eleven subfamilies.

TARGETS OF SEXUAL SELECTION: SONG AND PLUMAGE OF WOOD WARBLERS
TLDR
Overall, males of more dimorphic species sang shorter songs more often, but did not have more complex songs, while when monomorphic species were excluded from the analysis, it was found that the total time spent singing and repertoire size increased with plumage dimorphism.
Extrapair paternity and the evolution of bird song
TLDR
The absence of both intra- and interspecific relationships between measures of song variability and extrapair paternity suggests that factors other than postmating sexual selection have been the important evolutionary forces shaping differences in song.
A novel song parameter correlates with extra-pair paternity and reflects male longevity
TLDR
This new measure of singing performance was correlated with male longevity and with extra–pair paternity, indicating that females who copulated with better singers obtained ‘good gene’ for their offspring.

TLDR
Changes in acoustic features of song are found consistent with the hypothesis that coastal males are less able to meet the physical demands of song production because of the constraints of having larger bills and suggest a mechanism by which feeding ecology can influence signal evolution.
The evolution of bird song : comparative analyses
TLDR
The ecological and behavioural correlates of within- song complexity differ from those of between-song complexity, suggesting that they are not alternative solutions to the same selective pressures.
Uncorrelated evolution between vocal and plumage coloration traits in the trogons: a comparative study
TLDR
It was found that interspecific variation in male plumage coloration was not significantly predicted by song traits (reduced by PCA) or altitude, suggesting that sexual selection on male carotenoid‐derived coloration may be stronger than on melanin‐ or structurally based coloration, or than on acoustic traits.
Correlated evolution of morphology and vocal signal structure in Darwin's finches
TLDR
It is shown, in Darwin's finches of the Galápagos Islands, that diversification of beak morphology and body size has shaped patterns of vocal signal evolution, such that birds with large beaks and body sizes have evolved songs with comparatively low rates of syllable repetition and narrow frequency bandwidths.
Syllable type consistency is related to age, social status and reproductive success in the tropical mockingbird
TLDR
Evidence is presented that tropical mockingbirds decrease the variation between renditions of each syllable type as they grow older and that more consistent males in this species tend to have higher dominance status and reproductive success and it is hypothesized that syllabletype consistency may also be an indicator of the integrity of brain function in birds analogous to the tests used for neuropsychological assessment in humans.
Reproductive skew and selection on female ornamentation in social species
TLDR
The socially diverse African starlings (Sturnidae) are used to demonstrate that the degree of sexual dimorphism in plumage and body size is reduced in cooperatively breeding species as a result of increased selection on females for traits that increase access to reproductive opportunities, other resources, or higher social status.
Trill consistency is an age-related assessment signal in banded wrens
TLDR
It is shown that banded wrens reproduce the trill notes in their songs with less variability between them when they grow older, and it is argued that consistency in trill note reproduction may be achieved through practice.
