Are bird song complexity and song sharing shaped by habitat structure? An information theory and statistical approach.
In songbirds, song complexity and song sharing are features of prime importance for territorial defence and mate attraction. These aspects of song may be strongly influenced by changes in social… Expand

Nonpasserine bird produces soft calls and pays retaliation cost
Low-amplitude vocalizations produced during aggressive encounters, courtship, or both (quiet/soft songs) have been described for many species of song-learning passerines; however, such signals have… Expand

How do birds search for breeding areas at the landscape level? Interpatch movements of male ortolan buntings
Animal movements at large spatial scales are of great importance in population ecology, yet little is known due to practical problems following individuals across landscapes. We studied the whole… Expand

A Framework for Bioacoustic Vocalization Analysis Using Hidden Markov Models
TLDR
We apply Hidden Markov Models (HMMs) as a recognition framework for automatic classification of animal vocalizations using generalized spectral features that can be easily adjusted across species and HMM network topologies suited to each task. Expand

Frequency shift in homologue syllables of the Ortolan Bunting Emberiza hortulana
Results of this study indicate that in the Ortolan Bunting Emberiza hortulana, syllables of the same shape on sonograms (i.e. homologue syllables) often significantly differ between males in… Expand
