Sexual selection for both diversity and repetition in birdsong

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: June 16, 2023

From fiddler crabs to humans, animals perform repetitive displays showing neuromotor skill and vigour. Consistent repetition of identical notes (vocal consistency) facilitates the assessment skills is important in communication birds. Most birdsong research has focused on song diversity as a signal individual quality, which seems contradictory extremely common most species. Here we show that consistent within songs positively correlated with reproductive success male blue tits (Cyanistes caeruleus). A playback experiment shows females are sexually aroused by high levels vocal consistency, also peaks seasonally during fertile period female, supporting role consistency mate choice. Male increases subsequent repetitions same type (a warm-up effect) conflicts fact habituate repeated song, decreased arousal. Importantly, find switching types elicits significant dishabituation playback, habituation hypothesis an evolutionary mechanism driving An optimal balance between may explain singing style many bird species other animals.

An analysis of avian vocal performance at the note and song levels

Bioacoustics, Journal Year: 2019, Volume and Issue: 29(6), P. 709 - 730

Published: Oct. 16, 2019

Sexual displays that require extreme feats of physiological performance have the potential to reliably indicate signaller's skill or motivation. We tested for evidence constraints in Adelaide's warblers (Setophaga adelaidae) songs. At note level, we identified three trade-offs with well-defined limits. song two trade-offs, but their limits were less than note-level Trade-offs at both levels suggest structure is constrained by speed frequency modulation (while vocalising and between notes) respiration. Performance metrics derived from observed varied moderately among individuals strongly types. Note-level positively skewed, as predicted hypothesis constrained. conclude on respiration constrain male warblers. Further work needed determine whether receivers respond natural variation performance, correlates singer quality

Vocal performance increases rapidly during the dawn chorus in Adelaide’s warbler (Setophaga adelaidae)

Behavioral Ecology, Journal Year: 2023, Volume and Issue: 34(4), P. 621 - 630

Published: April 24, 2023

Abstract Many songbirds sing intensely during the early morning, resulting in a phenomenon known as dawn chorus. We tested hypothesis that male Adelaide’s warblers (Setophaga adelaidae) warm up their voices If warming voice is one of functions chorus, we predicted vocal performance would increase more rapidly chorus compared to rest morning and high song rates period contribute performance. The metrics recovery time, voiced frequency modulation, unvoiced modulation were low when birds first began singing, increased then leveled off or gradually diminished after dawn. These changes are attributable increasing within types.

Like Father Like Son: Cultural and Genetic Contributions to Song Inheritance in an Estrildid Finch

Frontiers in Psychology, Journal Year: 2021, Volume and Issue: 12

Social learning of vocalizations is integral to song inheritance in oscine passerines. However, other factors, such as genetic and the developmental environment, can also influence phenotype. The relative contributions these factors have a strong on evolution may affect important evolutionary processes speciation. are well-described only for few species likely vary with taxonomy. Using archived data, we examined patterns domestic population Java sparrows ( Lonchura oryzivora ), some which had been cross-fostered. Six-hundred seventy-six songs from 73 birds were segmented classified into notes note subtypes N = 22,972), range acoustic features measured.

Sound properties affect measurement of vocal consistency in birdsong: Validation of the spectrogram cross correlation method (SPCC)

The Journal of the Acoustical Society of America, Journal Year: 2023, Volume and Issue: 154(2), P. 699 - 708

Published: Aug. 1, 2023

In songbirds, singing with precision (vocal consistency) has been proposed to reflect whole-organism performance. Vocal consistency is measured using spectrogram cross correlation (SPCC) assess the acoustic similarity between subsequent renditions of same note. To quantify how SPCC sensitive discrepancies found in birdsong, we created a set 40 000 synthetic sounds that were designed based on songs 345 species. This included 10 reference and 30 inexact variants quantified differences frequency, bandwidth, or duration respect sounds. We within natural range vocal consistency, supporting use this method as tool songbirds. Importantly, sensitivity was significantly affected by bandwidth The predictions derived from analysis then validated 954 song recordings species (20 families). Based psychoacoustic studies birds humans, propose mirrors perceptual bias sound discrimination. Nevertheless, suggest be used care, since varies considerably styles therefore, scores may not comparable.
