A house finch (Haemorhous mexicanus) spleen transcriptome reveals intra- and interspecific patterns of gene expression, alternative splicing and genetic diversity in passerines [PDF]
, 2014 Background: With its plumage color dimorphism and unique history in North America, including a recent population expansion and an epizootic of Mycoplasma gallisepticum (MG), the house finch (Haemorhous mexicanus) is a model species for studying sexual ...

Maternal gut microbes shape the early-life assembly of gut microbiota in passerine chicks via nests
Microbiome, 2020 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
Nature Communications, 2022 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]
PLoS ONE, 2013 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]
PeerJ, 2020 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 low-cost hyperspectral scanner for natural imaging and the study of animal colour vision above and under water [PDF]
, 2019 Hyperspectral imaging is a widely used technology for industrial and scientific purposes, but the high cost and large size of commercial setups have made them impractical for most basic research.

A fast and accurate zebra finch syllable detector. [PDF]
PLoS ONE, 2017 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 ...

Automatic Construction of Predictive Neuron Models through Large Scale Assimilation of Electrophysiological Data. [PDF]
, 2016 We report on the construction of neuron models by assimilating electrophysiological data with large-scale constrained nonlinear optimization. The method implements interior point line parameter search to determine parameters from the responses to ...
