Vocal individuality has been used as a monitoring tool, and two criteria are a prerequisite: high variation among individuals and low variation within individuals, and vocal consistency within and across seasons. We examined individual variation in the territorial hoot calls of the tawny owl ( Strix aluco ) to discriminate between males and to assess a possible conservation technique that would allow for monitoring individuals within a study area. The territorial calls were recorded from five males in the Naejang Mountain National Park in South Korea during the breeding season in 2015 and 2016 and analyzed both quantitatively and qualitatively to determine the amount of variation within and between individuals. Our results showed that the territorial calls were specific to individuals within a population and that the acoustic distances between males living in the same territory during the two years were the smallest for the four nesting sites. Our results suggest that territorial calls of the tawny owls are individually identifiable over two years and that this acoustic technique can be useful for monitoring individual site fidelity.

“…Acoustics within the biological field regards the science knows as Bioacoustics, which aims at studying the production, dispersion, and reception of sound by/to animals (Lubis et al, 2016) whose cognitive and social skills are much revealed by the development level of their acoustic communication behavior (Ladich & Winkler, 2017). These capabilities are displayed by most vertebrate groups (Ladich & Winkler, 2017) and continuously constitute the focus of many studies that describe and classify emitted calls into vocal repertoires (Garcia & Favaro, 2017).…”

“…Notwithstanding, explaining them can be even a more difficult task when dealing with animals that do not commonly emit sounds in the field since, besides the lack of sound records, it is difficult to match communication with behavior. Extensive research has attempted to link sound production by a species with the context in which the species produced this sound (acoustic signals with their function) and the associated behavioral response triggered by this sound, as well as to understand the mechanisms involved in the vocal communication (Garcia & Favaro, 2017).…”

Acoustic analysis of vocalization and the behavioral response associated to sound production of the nine banded armadillo Dasypus novemcinctus (Mammalia, Cingulata, Dasypodidae) in an agonistic context

et al. 2022

Although communication capabilities are displayed by many vertebrate groups, some repertoires are poorly known, such as the case of xenarthrans, particularly armadillos, for which vocalization as a source of communicating to others remains poorly understood and relies on punctual reports of sounds. Here we provide the first description of a behavioral response associated with sound emission of two subjects of Dasypus novemcinctus. Both audio and visual registration was performed to subsequent analyses of expressed behaviors and emitted calls, which accounted for 76 vocalizations from a total of eight video recordings randomly collected from 2017 to 2019. Sound is acoustically characterized by both inhale and exhale phases composed of two vocal units, and no harmonic structure was observed. Once the subjects have always produced these vocalizations while cornered and exhibiting defensive behavior against another subject/human disturbance, these vocalizations were termed as distress. Subjects produced a hiss-purr-like sound while trying to avoid contact with another by bowing or lowering their bodies, humping, or even moving elsewhere when sound production ceased. This shows that the sound repertoire of armadillos is still to be unveiled and seems to be much more complex than previously thought.

“…to inform predators that they have been spotted or to alert sympatric species of danger; SABOL et al, 2022). While the study of animal sounds is a long established method for obtaining information on the ecology and status of species (BRADBURY et al, 1998;GARCIA and FAVARO, 2017), lower acquisition and operational costs of autonomous sound recording units (ARUs) and increased computational power of personal computers have led to a rapid increase in the number of researchers using passive acoustic monitoring (PAM) (SUGAI et al, 2019).…”

Passive acoustic monitoring is a wildlife monitoring method used especially for the study of vocally active species which are difficult to observe directly. The tawny owl (Strix aluco, Linnaeus 1758) is such a species, and has not been previously studied in Greece. The aim of the study was to provide a first insight into the species’ acoustic ecology in the Rhodope Mountains by describing its calling activity at four sites over a period of 3–6 months, and to examine possible correlation with natural and climatic parameters. Based on 24,937 calls, we report a significant increase in the number of calls per night (18:00 pm to 9:00 am) as the length of the night increased, as well as a negative relation with wind speed. We did not observe a relationship between calling frequency and the phase of the moon.
