Effect of Darkness on Intrinsic Motivation for Undirected Singing in Bengalese Finch (Lonchura striata Domestica): A Comparative Study With Zebra Finch (Taeniopygia guttata) [PDF]
Frontiers in Physiology, 2022 The zebra finch (ZF) and the Bengalese finch (BF) are animal models that have been commonly used for neurobiological studies on vocal learning. Although they largely share the brain structure for vocal learning and production, BFs produce more complex ...

Auditory and sexual preferences for a father’s song can co-emerge in female Bengalese finches [PDF]
PLoS ONE, 2022 Birdsong is an important communication signal used in mate choice. In some songbird species, only the males produce songs. While the females of those species do not sing, they are sensitive to inter- and intra-species song variations, and the song ...

Vocal learning promotes patterned inhibitory connectivity [PDF]
Nature Communications, 2017 Complex motor behaviors such as birdsong are learned through practice and are thought to depend on specific excitatory connectivity in premotor circuits.

High-throughput assessment of vocal modulation following chemogenetic inhibition in songbirds [PDF]
iScienceSummary: Chemogenetic tools that enable reversible manipulation of neuronal activity are essential for studying the neural bases of behavior, yet their application in songbirds remains limited.

Occurrence and vertical transmission of avian polyomavirus and circovirus in captive and wild Passeriformes in Poland [PDF]
BMC Veterinary ResearchBackground Diseases caused by polyomaviruses and circoviruses in parrots were first described in the 1980s. Then they began to be diagnosed in other orders of birds, including Passeriformes, such as Atlantic canaries (Serinus canaria) and estrildid and ...

Timing matters: age-dependent impacts of the social environment and host selection on the avian gut microbiota [PDF]
Microbiome, 2022 Background The establishment of the gut microbiota in early life is a critical process that influences the development and fitness of vertebrates. However, the relative influence of transmission from the early social environment and host selection ...

Lesions in a songbird vocal circuit increase variability in song syntax [PDF]
eLifeComplex skills like speech and dance are composed of ordered sequences of simpler elements, but the neuronal basis for the syntactic ordering of actions is poorly understood.

A compact statistical model of the song syntax in Bengalese finch. [PDF]
PLoS Computational Biology, 2011 Songs of many songbird species consist of variable sequences of a finite number of syllables. A common approach for characterizing the syntax of these complex syllable sequences is to use transition probabilities between the syllables. This is equivalent

Automated annotation of birdsong with a neural network that segments spectrograms [PDF]
eLife, 2022 Songbirds provide a powerful model system for studying sensory-motor learning. However, many analyses of birdsong require time-consuming, manual annotation of its elements, called syllables.

Cooperation of deterministic dynamics and random noise in production of complex syntactical avian song sequences: a neural network model [PDF]
Frontiers in Computational Neuroscience, 2011 How the brain learns and generates temporal sequences is a fundamental issue in neuroscience. The production of birdsongs, a process which involves complex learned sequences, provides researchers with an excellent biological model for this topic.
