Animal Vocal Communication and Behavior

This study investigates how demographic factors influence cultural evolution in bird song using a multi-generational dataset of Great Tits.

This study finds that female mice produce low rates of ultrasonic vocalizations during courtship and that these rates are not influenced by estrous state when interacting with muted males.

This study examines how internal and external context affect male mice vocal responses to female squeaks, finding that unfamiliar competitor odors reduce vocal production and complexity regardless of dominance status.

This study shows that deafened songbirds can maintain song stability using visual cues, as demonstrated by a new metric and behavioral task.

The paper observes and analyzes the mating behavior of Great Tinamous in their natural habitat, revealing that the female performs most courtship displays and songs, challenging previous assumptions about male courtship roles.

The paper investigates anatomical connections between the crow's NCL and its song system nuclei, finding dense projections to key song system nuclei and parallel pathways from MAN to NCL and HVC.

baRulho quantifies acoustic signal degradation in animal sounds through transmission experiments, showing higher degradation in closed habitats and for high-frequency sounds.

The paper examines the relationship between morphological and acoustic traits in mixed-species bird flocks, finding that species are more similar in body mass than expected but not in acoustic traits.

This study shows that perineuronal nets (PNNs) in motor circuits of songbirds are causally linked to the performance of learned vocalizations, with PNN degradation impairing song consistency.

This study shows prairie voles can recognize individual vocalizations of their mates, with acoustic variation across individuals allowing identification above chance.

This study finds that social isolation in a familiar environment does not suppress singing in zebra finches, unlike isolation in an unfamiliar environment.

This study uses statistical tests to infer partially observable Markov models of syllable transitions in Bengalese finch songs, showing that auditory feedback is crucial for context-dependent transitions.

The paper examines how early auditory and adult mating experiences influence neural responses to song in female zebra finches, revealing distinct patterns of neural activity based on rearing conditions.

This study shows that exposure to a complex acoustical environment during development improves auditory perception and coding efficiency in zebra finches.

The paper identifies a new type of aversive ultrasonic vocalization in male rats during prolonged fear conditioning and describes its characteristics and behavioral associations.

This study shows testosterone induces extensive transcriptional changes in the female canary's HVC, with 9,913 genes differentially expressed over two weeks, linked to neuronal and cellular processes.

This study shows that little auk social calls retain individual information over long distances, with negligible information loss down to the hearing threshold.

This study examines SETBP1 expression and regulation in zebra finch brain regions associated with singing, finding higher expression in solo singing and a regulatory role on FoxP2.

This study shows that female song in Alston's singing mice increases vocal display effort in both sexes, highlighting the social context of song in communication.

This paper conducts a meta-analysis of 371 effect sizes from 75 studies on acoustic adaptation hypothesis, finding no consistent support for vegetation structure affecting acoustic signaling across terrestrial vertebrates.

The paper shows different marmoset vocalizations activate distinct neural networks in the brain, suggesting specific processing for each call type.

This paper presents a computational model of songbird vocal learning that combines reinforcement learning and Hebbian plasticity to simulate song acquisition and weight transfer in neural circuits.

This study examines how urban sensory conditions affect rival interactions and mate choice in urban and forest tungara frogs, showing origin-dependent effects on sexual communication.

The paper examines if alpaca hums encode individual identity through acoustic features and finds spectro-temporal features provide more accurate classification than MFCC.

The paper analyzes neural activity in marmoset frontal cortex during natural vocal behaviors using a GLM model, finding distributed functional organization rather than distinct subfield specialization.

This study shows marmoset monkeys use active sampling in vocal interactions to gain information about their social environment, outperforming a vocal accommodation model.

This study examines the daily vocalization patterns of Saipan Reed Warblers, finding they sing throughout daylight without dawn or evening choruses.

This study investigates the role of auditory feedback in vocal production learning in Egyptian fruit-bats by deafening pups and analyzing adult vocalizations.

This study shows that reducing inhibition in a premotor area of adult zebra finches can restore vocal plasticity and allow new syllables to be added to their song after the critical period.

This study examines the ontogeny of sound production in Danionella cerebrum, finding that click production begins in the second month of life and increases in abundance and structure over the next one to two months.
