Abstract:

The Painted Button-quail Turnix varius is a widespread and frequently encountered ground-dwelling bird endemic to Australia. Despite being regularly recorded throughout its distribution, our understanding of this species’ vocalisations is poor. Published accounts are limited to brief descriptions without quantitative analyses in a standardised format. This presents challenges in separating the vocalisations of this species from other similar species, particularly as vocalising button-quail are seldom observed. We recorded the vocalisations of Painted Button-quail from North Queensland. These v

Abstract:

The call characteristics and distribution of blue whales in the North Pacific were examined by use of acoustic surveys. Two distinct vocalisation types have been previously attributed to blue whales from limited regions in the North Pacific (cf. Thompson and Friedl, 1982; Rivers, 1997). Hydrophone data from sixteen sites in the North Pacific were examined for these blue whale vocalisations. There were distinct geographic and seasonal differences between the occurrence of the two vocalisation types. The hydrophones that were more westerly recorded the ‘northwestern’ Pacific vocalisation, those

Abstract:

Recordings were made from a group of Risso's dolphins (Grampus griseus) off the coast of Newcastle, Australia, between 30 Hz and 22 kHz. Risso's dolphins exhibited seven separate vocalisation types: broadband clicks, barks, buzzes, grunts, chirps, whistles, and simultaneous whistle + burst-pulse sounds. Broadband clicks were highly variable in duration, with a frequency range of 6 to >22 kHz. Bark vocalisations consisted of highly variable burst pulses, with durations ranging from 0.2 to 7.4 s and a frequency range of 2-20 kHz. Buzz vocalisations were clearly stereotyped, consisting of a sh

Abstract:

Ultrasonic vocalisation is a broadly used proxy to evaluate social communication in mouse models of neuropsychiatric disorders. The efficacy and robustness of testing these models suffer from limited knowledge of the structure and functions of these vocalisations as well as of the way to analyse the data. We created mouseTube, an open database with a web interface, to facilitate sharing and comparison of ultrasonic vocalisations data and metadata attached to a recording file. Metadata describe 1) the acquisition procedure, e.g., hardware, software, sampling frequency, bit depth; 2) the biologi

AbstractPrevious studies have shown that the analysis of high frequency stress calls in pigs can serve as a reliable tool in welfare research. Our study focuses on the classification of three different classes of piglet vocalisation: grunting, squealing and screaming. In a castration experiment (Experiment 1), 3,285 vocalisations from 42 piglets were analysed for 21 different vocal characteristics. A first discriminant function for the three vocal types was derived from recordings made under laboratory-like conditions. A second discriminant function was derived from non-calibrated measurements

Abstract:

Button-quail (Turnicidae) are a greatly understudied family of birds; their cryptic habits make studying them in the wild challenging. They are known to be quite vocal which could assist with detectability, and so it follows that survey results will be more reliable as knowledge about button-quail vocal repertoire increases. Until recently, there were no published vocal recordings of the Chestnut-backed Button-quail Turnix castanotus, and descriptions and accounts of this species’ vocalisations were limited.

Abstract:

The social context in which a salient human vocalisation is heard shapes the affective information it conveys. However, few studies have investigated how visual contextual cues lead to differential processing of such vocalisations. The prefrontal cortex (PFC) is implicated in processing of contextual information and evaluation of saliency of vocalisations. Using functional Near-Infrared Spectroscopy (fNIRS), we investigated PFC responses of young adults (N = 18) to emotive infant and adult vocalisations while they passively viewed the scenes of two categories of environmental contexts: a domes

Abstract:

Heat stress is one of the most important environmental stressors facing poultry production and welfare worldwide. The detrimental effects of heat stress on poultry range from reduced growth and egg production to impaired health. Animal vocalisations are associated with different animal responses and can be used as useful indicators of the state of animal welfare. It is already known that specific chicken vocalisations such as alarm, squawk, and gakel calls are correlated with stressful events, and therefore, could be used as stress indicators in poultry monitoring systems.

Abstract:

Seabirds are highly vocal on land where acoustic communication plays a crucial role in reproduction. Yet, seabirds spend most of their life at sea. They have developed a number of morphological, physiological and behavioural adaptations to forage in the marine environment. The use of acoustic signals at sea could potentially enhance seabirds’ foraging success, but remains largely unexplored. Penguins emit vocalisations from the sea surface when commuting, a behaviour possibly associated with group formation at sea. Still, they are unique in their exceptional diving abilities and feed entirely

Abstract:

The study of non-human animals’ communication systems generally relies on the transcription of vocal sequences using a finite set of discrete units. This set is referred to as a vocal repertoire, which is specific to a species or a sub-group of a species. When conducted by human experts, the formal description of vocal repertoires can be laborious and/or biased. This motivates computerised assistance for this procedure, for which machine learning algorithms represent a good opportunity.

Here, we compared noise levels and activity, as well as calling activity and richness of aurally-identified species, between two sites; one near and one far from a road.

Abstract:

Long-term monitoring is needed to understand the statuses and trends of wildlife communities in montane forests, such as those in Yushan National Park (YSNP), Taiwan. Integrating passive acoustic monitoring (PAM) with an automated sound identifier, a long-term biodiversity monitoring project containing six PAM stations, was launched in YSNP in January 2020 and is currently ongoing. SILIC, an automated wildlife sound identification model, was used to extract sounds and species information from the recordings collected. Animal vocal activity can reflect their breeding status, behaviour, populati

Abstract:

Underwater vocalisations of grey seals (Halichoerus grypus) were recorded by static acoustic monitoring (SM2M, Wildlife Acoustics) in the vicinity of a colony located at White Strand beach on Great Blasket Island, southwest Ireland during the pre-breeding and breeding seasons. Grey seal vocalisations were first classified across nine different categories based on aural and visual characteristics of the spectrograms, providing an acoustic repertoire for grey seals. This classification was further investigated by applying a classification tree analysis, resulting in five of the initial nine grou

Abstract:

There have been few studies on the temporal patterns of social behaviours and how they relate to timing of life history stages in nocturnal colonial bird species. This study focuses on the threatened Westland petrel (Procellaria westlandica; Procellariidae), to investigate temporal patterns in colonial interactions, including vocalisations and social behaviours, in the context of petrel sociality. We conducted extensive behavioural observations on the colony at different time-scales (throughout single nights, between seasons, and across years) to characterise the temporal dynamics of at-colony

Context Polygynous deer rut vocalisations have been found to be highly conspicuous, typical of the species and important in sexual selection. Information about vocalisations is not available for Neotropical species (subfamily Odocoileinae). Aims The objective was to record courtship vocalisations from all Neotropical deer available, looking for differences among species useful for taxonomic identification, characterise the vocalisations according to acoustic parameters and to try to determine functions.

Abstract:

The intention of this article is to explore, challenge and expand our understandings of children's improvised vocalisations, a fundamentally human form of expression. Based on selected examples from observation and recording in non-institutional settings, the article outlines how this phenomenon can be understood as learning and as communication. This is supplemented by suggesting a third possible approach which places these vocal forms within the frame of understanding implied by Foucault's term ‘technology of the self’. This theoretical perspective entails recognising improvised vocalisation

Abstract:

The Omura’s whale (Balaenoptera omurai) is one of the most recently described species of baleen whale. Initially known only from stranding and whaling specimens, it has now been identified in all ocean basins excluding the central and eastern Pacific. Unlike most baleen whales that migrate between the poles and the equator seasonally, the Omura’s whale is known to inhabit tropical to sub-tropical waters year-round. In Australian waters, there remain fewer than 30 confirmed visual sightings over the past decade. However, based on acoustic records, the Omura’s whale has been detected off areas o

Abstract:

This paper combines perspectives from evolutionary biology and linguistics to discuss the early evolution of laughter and the possible role of laughter-like vocalisation as a bonding mechanism in hominins and early human species. From the perspective of evolutionary biology, we here emphasise several things: the role of exaptation, the typically very slow pace of evolutionary change, and the danger of projecting backwards from the current utilities of laughter to infer its earlier function, hundreds of thousands, or even millions, of years ago. From the perspective of linguistics, we examine b

The present study provided basic data regarding cattle farming on the basis of animal welfare, by using Hanwoo cattle (Bos taurus coreanae) vocalisations. We collected and analysed cattle-vocalisation data during situations that commonly occur during cattle farming (steer handling call, n = 130; heifer handling call, n = 418; heifer oestrus call, n = 454; heifer feed-anticipation call, n = 124; calf introduction call, n = 212) at a Hanwoo cattle farm and investigated differences in vocalisation parameters (call duration, call intensity, fundamental frequency, first formant, second formant, thi

Abstract:

The distribution and relative abundance of groups of striped dolphins (Stenella coeruleoalba) in the Ligurian Sea cetacean sanctuary, based on acoustic surveys carried out in the summers of 1994-1996, is presented. Abundance indices based on acoustic detections were adjusted for covariates likely to influence the detectability of dolphin vocalisations, such as wind speed, background noise and sea state. Dolphin vocalisation rates were shown to vary diurnally, being higher at night, and this effect was also modelled and removed. Results showed that dolphin groups were fairly evenly distributed

Abstract:

Sur Sarovar Bird Sanctuary is a Ramsar site which is located within the Agra region of Uttar Pradesh, India. The Red Wattled Lapwing is a resident of South Asia and has distinct vocalisations and ground nesting habits. Field observations were conducted over a six-month period and data related to certain behaviours including feeding habits, courtship rituals and interaction with other species were collected. A finding suggests that Red Wattled Lapwing exhibits strong territorial behaviour with males actively defending nesting sites. The role of vocalisation is not just important in communicatio

Abstract:

Cross-sensory correspondences automatically intrude on performance in elaborate laboratory tasks (see Spence 2011 Attention, Perception, & Psychophysics73 971–995, for a review). Outside such tasks, might they be responsible for some popular misconceptions about natural phenomena? Four simple demonstrations reveal how the correspondences between surface-lightness and weight, and between surface-lightness and auditory pitch, generate misconceptions about the weight and movement of objects and the vocalisations of animals. Specifically, people expect darker objects to be heavier than lighter

Abstract:

Vocal individuality could be used to estimate numbers of individuals in species otherwise difficult to monitor. However, the usefulness of this technique in providing conservation information is little studied. The vocalisations of the Corncrake show a high level of individual distinctiveness. This fact was used to examine current counting methods and estimate movement patterns within one breeding season. Information on individual identity gained from vocalisations increased census estimates by 20–30% and showed that male Corncrakes called less frequently than previous studies had suggested. M
