Song and brain structure are compared amongst 41 species of oscine birds by using the method of independent evolutionary contrasts. We find a significant correlation between the relative volume of the song control centre, the high vocal centre (HVC), and the number of song types typically found in the repertoire. Relative HVC volume is not correlated with the number of different syllable types per song bout. The relative volume of a second song nucleus, area X, is not significantly correlated… 

Figures and Tables from this paper

Evolutionary changes in a song control area of the brain (HVC) are associated with evolutionary changes in song repertoire among European warblers (Sylviidae)

TLDR
Investigation of covariation between singing behaviour and the neuroanatomy in eight species of sylviid warblers from the closely related Acrocephalus and Locustella genera finds a significant positive correlation between repertoire size and the volume of the higher vocal centre.

Individual variation in neuron number predicts differences in the propensity for avian vocal imitation.

TLDR
It is found that individual differences in HVc volume and neuron number correlated positively with differences in the number of tutor syllables accurately copied, and it is possible that naturally occurring variation in neuron number constrains how much song material can be copied or reproduced.

Sexually size dimorphic brains and song complexity in passerine birds

TLDR
No role is suggested for the evolution of extended neural space, as reflected by total brain size, owing to song complexity, but factors associated with sexual selection mirrored by sex differences in song complexity were related to sexual dimorphism in overall brain size.

Comparative Analyses of Song Complexity and Song-Control Nuclei in Fourteen Oscine Species

TLDR
The results indicated that the relationship between song behavior and its neural structures varied among song nuclei, suggesting that each song control nucleus may play a different role in song behavior.

Comparative approaches to the avian song system.

TLDR
Whether the vocal control systems of parrots and songbirds were inherited from a common ancestor or independently evolved, and at what stage in the phylogeny of songbirds the hormone-sensitive forebrain circuit found in modern birds first evolved are considered.

Variation in the volume of zebra finch song control nuclei is heritable: developmental and evolutionary implications

TLDR
Evidence that the size of the HVC and other song production nuclei are heritable across individual males within a species is provided, and it is found that heritabilities of other nuclei in a song-learning pathway are lower, suggesting that variation in the sizes of these structures is more closely tied to developmental and environmental differences between individuals.

Neural Constraints on the Complexity of Avian Song

TLDR
Evidence that females may do so because male song can be an honest indicator of attributes of a male’s brain that could contribute to his fitness or that of his young is reviewed.

Neural correlates of singing behavior in male zebra finches (Taeniopygia guttata).

TLDR
It is indicated that the evidence for a general relationship among songbirds between HVC volume and song complexity is equivocal and there are clear species differences in this brain-behavior correlation.

Sexual Selection for Song Complexity and Modifications of Brain Structures in Songbirds

TLDR
To study further the relationship between brain evolution and sexual selection in birdsong, methods for measuring song complexity need to be refined and other anatomical indexes besides volumetric methods should be examined.

Song-related brain regions in the red-winged blackbird are affected by sex and season but not repertoire size.

TLDR
Seasonal change in song system structures in male redwings is consistent with there being a relation between adult plasticity in anatomy and in behavior; the large seasonal change in these structures in females suggests large seasonal changes in the function of these nuclei.

TLDR
This review of some of the characteristics of avian vocal learning as derived from behavioural studies indicates lacunae in the authors' knowledge about the ethology of song learning, and suggests how the comparative study of vocal development can pave the way for new insights into the underlying neurobiology.

Song learning in birds: the relation between perception and production.

TLDR
The vocal control system of oscine songbirds has some perplexing properties that are not predicted by common views of how vocal learning takes place and the relation between the direct pathway for the control of learned song and the recursive pathway necessary for song learning is not understood.

Seasonal changes in avian song nuclei without seasonal changes in song repertoire

TLDR
Seasonal variation in the size of song nuclei in the brains of male songbirds may be related to the ability to learn to sing new songs as adults, and synaptic plasticity provided by such seasonal variation may enable song learning by adult birds.

TLDR
It is concluded that Area X and LMAN contribute differently to song acquisition: the song variability that is typical of vocal development persists following early deafness or lesions of Area X but ends abruptly following removal of LMAN.

A brain for all seasons: cyclical anatomical changes in song control nuclei of the canary brain.

TLDR
Male canaries that have reached sexual maturity can, in subsequent years, learn new song repertoires and two telencephalic song control nuclei are hypothesized to reflect an increase and then reduction in numbers of synapses and are related to the yearly ability to acquire new motor coordinations.

Song Types in a Population of Great Tits (Parus Major): Their Distribution, Abundance and Acquisition By Individuals

TLDR
This 6-year study of song acquisition in a marked population of great tits suggests that songs are learned both before and after dispersal, songs are not learned from fathers and size of repertoire is not related to male age.

Complex organization of the warbling song in the European starling Sturnus vulgaris

TLDR
The present study describes the structure and the organization of warbling song in individuals from varied geographical origins, showing warbling to be an extremely complex song in which there is much contrast.
