Article
Dominika Winiarska, Auteur ; Paweł Szymański, Auteur ; Tomasz S. Osiejuk, AuteurPassive acoustic monitoring (PAM) efforts have recently been accelerated by the development of automated detection tools, enabling quick and reliable analysis of recordings. However, automated methods are still susceptible to errors, and human p[...]
Article
Mathieu Mahamoud-Issa, Auteur ; Bożena Sikora, Auteur ; Katarzyna Łosak, Auteur ; Tomasz S. Osiejuk, AuteurThe Yellow-breasted Barbet (Trachyphonus margaritatus) is a group-living and chorusing bird species. However, its vocal repertoire remains poorly described. In this study, we measured the acoustic features of four distinct vocalisations as well [...]
Article
Mathieu Mahamoud Issa, Auteur ; Bożena Sikora, Auteur ; Stanisław Rusiecki, Auteur ; Tomasz S. Osiejuk, AuteurCooperative behaviour is a prominent feature among many group-living species and continues to pose challenges to our understanding about the evolution of social relationships and task coordination between members of the same social group. Indivi[...]
Article
Michał Budka, Auteur ; Anna Skierczyńska, Auteur ; Marcin Antczak, Auteur ; Tomasz S. Osiejuk, AuteurMost bird species are active by day. However, even typically diurnal species have been observed to sing by night, although the functions and mechanisms of this behaviour are not well understood. In our study, we focused on nocturnal singing by d[...]
Article
Aleksandra Jakubowska, Auteur ; Tomasz S. Osiejuk, AuteurAnimals from many taxa produce low amplitude acoustic signals. In some birds such soft signals were found to be uttered in aggressive context and were the best predictor of subsequent physical attack. This phenomenon is poorly understood and sev[...]
Article
Paweł Szymański, Auteur ; Krzysztof Deoniziak, Auteur ; Katarzyna Łosak, Auteur ; Tomasz S. Osiejuk, AuteurDans Ibis (159(4) 2017)The rapid development of wind energy may have negative effects on bird populations, including collisions with turbines, displacement due to disturbance or habitat loss, indirect effects of reduced breeding success and barrier effects. This chall[...]
Article
Michał Budka, Auteur ; Tomasz S. Osiejuk, AuteurMicrogeographic variation in bird song has been studied in many species. However, it remains to be more fully described in birds that do not learn song and that thus have largely innate vocalisations. In this study, we focused on microgeographic[...]
Article
Michał Budka, Auteur ; Lucyna Wojas, Auteur ; Tomasz S. Osiejuk, AuteurAcoustically identifying individuals may be a helpful technique when it is necessary to monitor animal populations over space and time. Previous studies have largely focused on the theoretical exploitation of vocal individuality or have looked a[...]
Article
Gunvar Mikkelsen, Auteur ; Svein Dale, Auteur ; Thorstein Holtskog, Auteur ; Michal Budka, Auteur ; Tomasz S. Osiejuk, AuteurMovements of animals at large spatial scales are important in ecology and conservation biology, but current methods for monitoring long-distance movements (e.g. ringing or telemetry) are resource demanding and limit sample sizes. Many birds have[...]
Article
Tomasz S. Osiejuk, Auteur ; Katarzyna Losak, Auteur ; Svein Dale, AuteurSeveral studies demonstrated that bird song functions as a first line of territorial defence. The efficiency of deterring rivals depends strongly on the strategy of singing used (e.g. alternating/overlapping singing, singing with low/high rate, [...]

Article
Ewa Węgrzyn, Auteur ; Konrad Leniowski, Auteur ; Tomasz S. Osiejuk, AuteurWe analyzed a set of frequency and temporal characteristics of the introductory syllables in the song of the Great Reed Warbler (Acrocephalus arundinaceus) to assess their potential for individual recognition. We also tested if the initial sylla[...]
Article
Michal Budka, Auteur ; Gunvar Mikkelsen, Auteur ; Lucia Turčoková, Auteur ; Yoan Fourcade, Auteur ; Svein Dale, Auteur ; Tomasz S. Osiejuk, AuteurThis study was conducted to characterise macrogeographic variation in the vocalisation of the corncrake Crex crex, a bird species with a non-learned and highly stereotyped call. We also examined: 1) whether call characteristics remained stable a[...]
Article
Michal Budka, Auteur ; Tomasz S. Osiejuk, AuteurThe acoustic signals of birds are commonly used for individual recognition. Calls or songs allow discrimination between parent and offspring, between mates and between territorial neighbours and strangers. In this study, we investigated vocal ne[...]
Article
Michal Skierczynski, Auteur ; Kamila M. Czarnecka, Auteur ; Tomasz S. Osiejuk, AuteurNeighbour-stranger discrimination has been demonstrated in many species, but the mechanisms employed in discrimination vary. We tested whether an oscine bird with small repertoire size, the ortolan bunting Emberiza hortulana, discriminated betwe[...]
Article
The song of the Cinnamon-breasted Bunting, Emberiza tahapisi, in the Bamenda Highlands (NW Cameroon)
In this study, I describe the song of the Cinnamon-breasted Bunting (Emberiza tahapisi)-a common and widespread species in sub-Saharan Africa. Several aspects of song behaviour were addressed based on recordings of 58 males in the Bamenda Highla[...]
Article
Lucia Turčoková, Auteur ; Tomasz S. Osiejuk, Auteur ; Václav Pavel, Auteur ; Jakub Glapan, Auteur ; Tereza Petrusková, AuteurAs birds adapt to changing biotic and abiotic environmental conditions, parameters of their acoustic signals are modified by selective pressure for efficient communication. Such changes in song features may result in acoustic divergence among po[...]
