Parental influence on begging call structure in zebra finches (Taeniopygia guttata): evidence of early vocal plasticity [PDF]
Begging calls are signals of need used by young birds to elicit care from adults. Different theoretical frameworks have been proposed to understand this parent–offspring communication. But relationships between parental response and begging intensity, or

Genomic and neural analysis of the estradiol-synthetic pathway in the zebra finch
Background Steroids are small molecule hormones derived from cholesterol. Steroids affect many tissues, including the brain. In the zebra finch, estrogenic steroids are particularly interesting because they masculinize the neural circuit that controls ...

Maternal gut microbes shape the early-life assembly of gut microbiota in passerine chicks via nests
Background Knowledge is growing on how gut microbiota are established, but the effects of maternal symbiotic microbes throughout early microbial successions in birds remain elusive.

Neural circuit for social authentication in song learning
Human and bird infants acquire vocal patterns from live, not mimetic, tutors. Here, the authors identified the neuronal circuits to authenticate social information in zebra finch song learning, suggesting a brain developmental mechanism via social ...

A daily oscillation in the fundamental frequency and amplitude of harmonic syllables of zebra finch song. [PDF]
Complex motor skills are more difficult to perform at certain points in the day (for example, shortly after waking), but the daily trajectory of motor-skill error is more difficult to predict.

Auditory processing in the zebra finch midbrain: single unit responses and effect of rearing experience [PDF]
In birds the auditory system plays a key role in providing the sensory input used to discriminate between conspecific and heterospecific vocal signals. In those species that are known to learn their vocalizations, for example, songbirds, it is generally ...

A fast and accurate zebra finch syllable detector. [PDF]
The song of the adult male zebra finch is strikingly stereotyped. Efforts to understand motor output, pattern generation, and learning have taken advantage of this consistency by investigating the bird's ability to modify specific parts of song under ...

Female Zebra Finches Smell Their Eggs
Parental investment in unrelated offspring seems maladaptive from an evolutionary perspective, due to the costs of energy and resources that cannot be invested in related offspring at the same time. Therefore selection should favour mechanisms to discriminate between own and foreign offspring.

The potential role of Arhgef33 RhoGEF in foveal development in the zebra finch retina
The fovea is a pit formed in the center of the retina that enables high-acuity vision in certain vertebrate species. While formation of the fovea fascinates many researchers, the molecular mechanisms underlying foveal development are poorly understood ...

Increases in the scale and complexity of behavioral data pose an increasing challenge for data analysis. A common strategy involves replacing entire behaviors with small numbers of handpicked, domain-specific features, but this approach suffers from ...
