Animal Vocal Communication and Behavior

The paper shows that dopamine transients at song motif onset are needed to maintain accurate adult zebra finch song, a naturally learned skilled behavior.

The study finds that song sparrows do not distinguish between current and historical songs despite detectable changes in song structure over 27-29 years.

The paper tests the causal role of the auditory forebrain and ERK/mTOR signaling in female sensory song learning in zebra finches, finding mTOR signaling is sex-specific.

This study shows that Western Australian magpies comprehend complex call sequences before they can produce them, suggesting rapid learning or innate understanding of sequence meaning.

The paper investigates whether vocal building blocks in magpies are innate or learned, finding no acoustic development over time and supporting innate elements underpinning call sequences.

The paper quantifies communication networks in wild zebra finches using song recordings and deep learning, revealing higher activity at social hotspots and dynamic, non-nested networks.

The paper develops a lightweight acoustic classifier for detecting rare vocalisations of the invasive small Indian mongoose using sparse data, but finds limited utility due to small training datasets.

This paper introduces Moove, a real-time system for segmenting and classifying Bengalese finch syllables, enabling effective operant conditioning experiments.

The paper shows Western Australian magpies use multi-level structured ordering rules in their call sequences, indicating learned syntactic structure.

The paper examines context-dependent vocal behavior in Emerald glass frogs, finding that males adjust call characteristics based on social context.

The paper compares acoustic space use in human and primate vocalizations, finding speech and song occupy less acoustic space than non-linguistic human vocalizations and are not distinct from non-human primates.

The paper reviews evidence for the acoustic space partitioning hypothesis, finding strong support but highlighting methodological gaps and alternative explanations for signal differentiation.

The paper examines volubility and vocal coordination in common marmosets under different experimental conditions, finding call-type-specific patterns of vocal contagion and recruitment.

This study optimizes CNNs for bird identification in urban tropical ecosystems and compares their performance to traditional methods, finding higher species richness estimates from CNNs.

The paper investigates how pair bonding in songbirds alters neural responses to familiar songs in specific auditory and integrative circuits, with a potential role for dopamine.

This study examines how urbanization and ecological factors influence song frequency traits in Spotted and Eastern towhees using geographic and environmental data.

This study shows that Mongolian gerbils coordinate their ultrasonic vocalizations with their partners' vocal timing, exhibiting turn-taking behavior and reduced overlap.

This study shows that Bengalese finches can learn to modify their songs by associating food rewards with auditory cues during singing.

This study quantifies the vocal repertoire of adult common terns by analyzing acoustic data from a breeding colony, identifying distinct call types and their acoustic parameters.

The paper shows neurons in bat auditory cortex encode vocalization class and temporal complexity before vocal onset.

The paper examines gene expression changes in song sparrows exposed to local vs. foreign songs, finding differential expression in genes related to song perception, anti-inflammatory responses, and energy metabolism.

The paper compares BirdNET, expert listening, and acoustic indices for monitoring avian diversity in an agricultural landscape, finding BirdNET detects more species but with potential reliability issues.

This paper presents a computational model of songbird vocal learning that uses a dual pathway architecture to achieve robust sensorimotor learning and outperforms standard reinforcement learning approaches.

This study uses Bayesian phylogenetic models to analyze song complexity in suboscine birds, finding that sexual selection reduces complexity while territoriality increases it, challenging the dominance of sexual selection as the primary driver.

This study shows that juvenile pigs process emotionally valenced vocalizations differently, activating distinct brain regions related to emotion and reward.

The paper investigates macro-scale cortical dynamics during marmoset vocal interactions, identifying traveling waves that integrate perception, response selection, and vocal production.

The paper shows that repeat numbers of distant phrases in Bengalese finch songs are correlated, suggesting a joint factor controls nonadjacent phrases, challenging existing Markov chain models of song syntax.

This study identifies specific cortico-basal ganglia synapses critical for rapid vocal learning in juvenile zebra finches and characterizes the timescale of consolidation.

The paper shows that higher bird species diversity increases public information about predation through mobbing and alarm calls, enhancing the quantity and quality of interspecific information flow.

This study shows that knocking down FOXP2 in the striatum of marmoset monkeys disrupts vocalization stability, revealing a role for FOXP2 in primate vocal production.
