Birdsong differs from other sexual traits in that the acquisition process involves learning. Especially in close-ended learning species like the Bengalese finch, conditions experienced during the critical song-learning period can have a profound influence on song quality. Therefore, to understand song evolution from a life-history perspective, we investigated early ontogenetic effects on song quality. In particular, we focused on maternal effects and sibling competition. In asynchronously… 

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

It is suggested that high learning fidelity of song material, i.e., song structure and note characteristics, could allow novel variants to be preserved and accumulate over generations, with implications for evolution and conservation.

Differential allocation in relation to mate song quality in the Bengalese finch

It is found that clutch size and egg mass were highly repeatable within individual females while sex ratio was not, and females mated to better mates adjusted their reproductive investment by producing heavier eggs and possibly offspring of the more costly sex.

Oviposition drives hatching order and developmental disparities with brood mates

It is discovered that the experimental elevation of oviposition—which controlled for egg composition—delayed hatching, inhibited growth and widened bill gape, thus confirming the mechanism for hatching order and revealing a potential role for Oviposition in reproductive success.

Phylogeography, song divergence and reproductive isolation in two species of songbird

For two species of songbird, the American Redstart and the Black-throated Blue Warbler, it is found that the causes of the divergence between populations may include sexual selection, as songs in the northern population have faster trills, and sexual selection favors fast trills in this population.

Early life and transgenerational stressors impact secondary sexual traits and fitness

Male zebra finches were colony-reared on highor low-quality diets; as adults, they reproduced competitively on an intermediate diet, and findings suggest that the sexes respond differently to early life conditions, which may influence subsequent sex allocation patterns.

Singing the Popular Songs? Nightingales Share More Song Types with Their Breeding Population in Their Second Season than in Their First

Nightingales adjusted their singing towards the songs popular in the breeding grounds by keeping song types that were common and frequently sung by other individuals in their breeding area and by disposing of infrequently performed ones, which resulted in increased similarity with the population’s repertoire from the first to the second year.

Are commonly used metrics of bird song complexity concordant?

Results indicated that none of the metrics positively correlated with any others, suggesting that bird songs are not under general selective pressures favoring increased complexity across multiple features, and care should be taken when designing analyses and comparing results.



Early Rearing Conditions Affect the Development of Body Size and Song in Bengalese Finches

These findings are the first to show that developmental condition affects not only the number of note types but also the syntactical complexity of the song and support the developmental stress hypothesis.

Early condition, song learning, and the volume of song brain nuclei in the zebra finch (Taeniopygia guttata).

The results provide no evidence for song learning to be limited by nestling condition during the period of nutritional dependence from the parents in the zebra finch.

Developmental stress impairs song complexity but not learning accuracy in non-domesticated zebra finches (Taeniopygia guttata)

It is found that song complexity when measured by a linear combination of six variables was reduced in food-restricted birds, with syllable rate and maximum syllable frequency as the principal variables affected, demonstrating that early nutrition may differentially affect the development of neural processes that influence learning accuracy and song complexity.

Sex-specific maternal effect on egg mass, laying order, and sibling competition in the Bengalese finch (Lonchura striata var. domestica)

Overall patterns of maternal investment favored the disadvantageous sectors of sibling competition, i.e., eggs of later laying order and sons over those of early laying orderand daughters, and the effect of laying order on adult body size and sex differences in growth patterns was examined.

Song Learning, Early Nutrition and Sexual Selection in Songbirds

A new hypothesis is presented for the adaptive significance of song learning in songbirds, suggesting that this specialized form of vocal development provides an indicator mechanism by which females can accurately assess the quality of potential mates.

Developmental stress, social rank and song complexity in the European starling (Sturnus vulgaris)

Investigating the effects of food restriction and social status during development on song complexity in the European starling provides novel evidence that social as well as nutritional history may be important in shaping the song signal in this species.

Developmental stress selectively affects the song control nucleus HVC in the zebra finch

The results explain how the complex song repertoires of songbirds can evolve as honest indicators of male quality and show that both environmental and genetic factors affect the development of several brain nuclei, highlighting the developmental plasticity of the songbird brain.

Early nutritional stress impairs development of a song-control brain region in both male and female juvenile song sparrows (Melospiza melodia) at the onset of song learning

This study examined the effect of food restriction on song-control brain regions in fledgling (both sexes, 23–26 days old) song sparrows (Melospiza melodia) and found that food restriction selectively reduced HVC volume in both sexes.

Parasites affect song complexity and neural development in a songbird

It is shown that adult male canaries, infected with malaria as juveniles, develop simpler songs as adults compared to uninfected individuals, and exhibit reduced development of the high vocal centre (HVC) song nucleus in the brain.
